Title: 87 savage carb problems "Help"!!
Post by ALRICH on 09/09/07 at 16:17:06

Got my timing reset on my savage. So now it starts and runs but it will only run with the choke on. And when you get on the gas it wants to die. I dont get it?? Maybe either flooding or not enough gas. Anyone got any idea's??

How long has it been sitting?

Slide could be either stuck or diaphram bad so it is only geting air via the cold enrichment passage, it really isn't a choke like you might think. It is a parallel air/fuel mising device that bypasses the slide so it can run a little faster and richer when cold. Max

That's what I was thinking too.That's why I was asking how long it sat.

Post by ALRICH on 09/09/07 at 17:24:28

It hasn't been sitting long at all I just took the carb apart soak it and cleaned it. The slide is alittle slow to come down when you push it up.

Post by ALRICH on 09/09/07 at 17:25:42

another thing if it was the slide diafram where would I get one??

It's a stealership item I believe.Most everybody in here orders their parts from bike bandit or Ron Ayers.Don't fall over when you see the price.I would check yours first if you soaked carb take the diaphram out CAREFULLY clean it ,dry it ,check for cracks ,whatever.Make sure when you put it back together it goes the right way.There is a tab on the diaphram that goes in a notch on carb body.

Post by ALRICH on 09/09/07 at 17:52:36

I will check that tommorrow and see if it has any cracks in it. I am probly not going to like the price of one if I have to replace it. Does it sound like it is getting to much fuel though??

Title: Re: 87 savage carb problems "Help"!!
Post by demin on 09/09/07 at 17:56:18

No I don't think it's rich if you have to choke it.I'm with Max what he said above.

Title: Re: 87 savage carb problems "Help"!!
Post by ALRICH on 09/09/07 at 17:59:56

Alright thanks for the help I will check the slide and diafram tommorrow I hope it isnt that.

Title: Re: 87 savage carb problems "Help"!!
Post by demin on 09/09/07 at 18:03:56

If it ran before,I kinda doubt it.My bet it has some gunk making it stick.

Looks like another person who has the same problem I have. It really is a common Savage thing isn't it??

Good luck with getting it fixed!

Title: Re: 87 savage carb problems "Help"!!
Post by ALRICH on 09/10/07 at 03:57:10

I might end up rebuilding the entire carb but it will get fixed. Of cousre there is always the option of ebay to get an entire carb. Only problem with that is you might get a carb with worse problems.

Maybe check the pilot jet- mine was doing about the same thing and that jet was almost completely closed off with crud. Also, I'd say check the o-ring on the needle jet just in case...

Title: Re: 87 savage carb problems "Help"!!
Post by ALRICH on 09/10/07 at 05:27:09

will check that tis morning when I tear it apart thanks for the info

Title: Re: 87 savage carb problems "Help"!!
Post by ALRICH on 09/10/07 at 06:42:12

Alright pulled carb completely apart. And have found nothing that would make it stick. enrichment valve diaphram looked alittle questionable. I have an new one so I will go ahead and replace it. Needle jet wasnt clogged up at all. Diaphragm assemble in the top also look questionable. It does slide up and down when in the carb but is alittle slow to come back down. I was thinking maybe the spring isnt any good anymore??

Title: Re: 87 savage carb problems "Help"!!
Post by Reelthing on 09/10/07 at 08:11:02

that diaphram and silde need to be really clean - not even a fingerprint - as well as the slide bore - if your careful you can stretch out the spring a little to give more down force - you say the top of the diaphram looks questionable? as in some holes or cracks?

Title: Re: 87 savage carb problems "Help"!!
Post by ALRICH on 09/10/07 at 08:35:11

The diaphram just looks kind of winkled like it is old. Also the slide has a bunch of black stuff all over it I will try to clean it off the best I can. also the slide has some scoring marks all the way around it.

Title: Re: 87 savage carb problems "Help"!!
Post by verslagen1 on 09/10/07 at 08:47:27

There's your problem, get that black stuff off of there.

600 paper works great.

Title: Re: 87 savage carb problems "Help"!!
Post by ALRICH on 09/10/07 at 08:53:50

will go get some 600 grit this afternoon thanks for the help I hope it works. Do you have any idea what that black stuff is?? Maybe old gas??

Title: Re: 87 savage carb problems "Help"!!
Post by verslagen1 on 09/10/07 at 10:11:17

varnish and dirt.

When I 1st saw mine I thought it was dry lube it was so consistent I thought it was supposed to be there. After I cleaned it I gained 2-3 mpg. And maybe this is when I also started noticing clutch slip. So a little snappier responding throttle. ;D

Title: Re: 87 savage carb problems "Help"!!
Post by ALRICH on 09/10/07 at 12:40:22

Well I completly cleaned and dismantled carb put it back togather and it is still not wanting to run. When I first put the carb back on it it fired right up with the choke and ran like a new bike. But then it wouldnt stay running. After trying to start it a couple times with choke again it just would not start. Anyone think I should start looking at the coil or some other eletrical problem?? There is no way it could be the carb there isnt any dirt in it it is so clean I could eat off it.

Title: Re: 87 savage carb problems "Help"!!
Post by islandwahine on 09/10/07 at 12:45:09

I'm probably not much help, but did you take a peek at the petcork? Maybe the filter part is all clogged up? What's the spark plug looking like? You probably already checked those things, but in case you didn't I thought that those might be possible reasons.

Title: Re: 87 savage carb problems "Help"!!
Post by ALRICH on 09/10/07 at 13:45:55

I bought that pet thingy brand new and the tank had been cleaned out. It has really got me stumped.

Title: Re: 87 savage carb problems "Help"!!
Post by islandwahine on 09/10/07 at 15:35:22

I assume that the airfilter is new too?

Title: Re: 87 savage carb problems "Help"!!
Post by T-Mack1 on 09/10/07 at 19:43:57

Remember that the carb basically has three fuel circuits. Low speed, mid and high. For the low, the pilot jet and air mixture screw (pilot screw, low speed mixture screw ....pick one). Then for mid-range the needle comes into play. After that is the main jet.

So, if you can idle with the choke on but not without it, that means you need more fuel at low speed. I would adjust low speed mix screw in both directions to find out where the "too lean" and "too rich" points are. If you can't get to the too rich point, then either there is small amount of unseen dirt (Holes are small, doesn't take much) or the mod's done before you got the bike require more fuel (because it's getting more air now) and you need a bigger pilot jet.

Next, sounds like it bogs when you hit the throttle. Well, that is the hard one to diagnost. If it is just above idle then it's the needle circuit (diagphram/slide assembly thingy). IF you are bogging down due to too much fuel, the spark plug will be getting black. If you are bogging down from lack of fuel, spark plug will be clean(er). Lack of fuel would be a modification of the white spacer. Too much fuel I think is diagphram (never had to play with this so the forum may need step in here).

If you get the bike rolling but bogs when you hit the throttle to get into traffiic, then would be in main jet circuit. Puff's of black smoke when rev'ing are an indication of too rich. Too lean would manifest itself in multiple ways (blue'ing pipes, back firing (w/ no smoke). Spark plug again is your eyes as to what is going on inside the chamber.

Hope this helps you look at the correct circuit to concentrate on.

I would first get the bike to idle without the choke.

Isn`t that black stuff on the slide a teflon coating??????

Air filter is also new

Post by ALRICH on 09/11/07 at 02:30:13

I think I found my problem finally. Las night when I was trying to get it running. I decided to drain some gas out of the petcock to see if it smelled like bad gas or anything. Well I found there to be water in it. So I drained the tank and carb. Went got some more gas from the same station that I got the las gas from not even thinking about it.

When I filled it up the bike ran without the choke for about 2 minutes then starting bogging down again. Ass soon as I opened the float bowl again there was more water in the tank. So I will try some differnt gas today. But that has got to be it. Hell it cant run on water.

LOOKING FOR SUGGESTIONS ON CLEANING OUT A GAS TANK??

Title: Re: 87 savage carb problems "Help"!!
Post by T-Mack1 on 09/11/07 at 09:32:00

1) get a gas can.
2) take fuel hose off carb (left side of carb), and put in gas can. (May need soemthing to get can up to hose)
3) Turn petc0ck to PRI.
4) let drain all the way.

5) Optional: remove petc0ck to get last drops out.
6) Optional 2: also remove tank from bike and really really get out last drops.

STP fuel teatment helps disperse water but a product called DRI-Gas (or Dry-gas) works best. It for northern climates, where the water freezes in the bottom of car gas tanks in the winter.

You may want to check the gasket on the fuel cap for a good seal. Avoid spraying water directly on or around cap when washing bike.....

I have got some rust and other stuff in there I am trying to figure out how to get out?

Title: Re: 87 savage carb problems "Help"!!
Post by T-Mack1 on 09/11/07 at 09:42:04

They make a tank cleaner the chemically removes the rust but I can't remember the name. My friend uses it on his old Honda's. Stuff he uses is an overnight thing that gets mixed with water.

You probably should take tank off bike for close inspection. Rust can create pin holes after being cleaned.

Title: Re: 87 savage carb problems "Help"!!
Post by ALRICH on 09/11/07 at 11:17:31

I may try the tank cleaner I am not sure I dont want to end up with a hole in this tank. Bike runs like a champ since I got some good gas in it.

I want to thank everyone in here for there very helpful info. Without you guys I probly wouldnt have gotten it fixed. THANKS AGAIN!!!

Put an inline fuel filter on your fuel line - especially if you have rust in the tank.
