Title: need choke instructions
Post by islandwahine on 08/23/07 at 00:15:04

Aloha,
I ran a search on choke problems, and I found one that sounded like my problem, but I lost it and can't seem to find it again. I'm not quit sure how to phrase my search to find what I need.
I can only ride my bike with the choke either all the way, or half pulled out. Even after an hour of riding (which in my eyes should have warmed it up enough) I still have to keep it pulled out. The one quote I found said something about filing of a little of the carb needle? It would be great if anyone could direct me to the topic that has the complete directions.

You can check out the carb adjustment threads in the Tech section. Or do a search on the word "choke".

You could also search on "enrich" or "richen" since it's truly an enrichener rather than a choke. Both make the mixture richer. The difference is that a choke reduces the air and an enrichener adds fuel. Anyway, my point is that some posts may use the more accurate terminology.

I did a search on choke, that's how I found the post about filing the needle off a bit. It hadn't entered my mind to search for carb. I guess that's my problem with the search; not knowing the correct terminology.

Before You start messing with different things, did You try to adjust the idle RPMs? Does Your bike run good once You take off and You push the choke IN ?
If everything is peachy exept the bike dieing when You let off the gas, You might have to raise the idle a little bit.
Otherwise You either have to adjust the idle mix. screw /the little brass screw in the right front side of the carb/, or if this doesn't help, You might have a plugged idle jet.
The spacer and the needle control the mixture above idle speed, so this is not what You should have to touch.

Yeah, I think just reading the stuff in the Carbs section of the Tech Ref TOC and then using Lancer's Straight & Simple Carb Tuning would be a great place to start... before thinking about cracking the carb. Then, if you decide to, I believe it's the white spacer you'd want to shave/file down - not the needle.

Actually it's the other way around. It idles just fine (I did adjust the little screw for a smoother idle), but it doesn't want to ride without the choke being pulled out some.

I hope you dont start filing on things before a lot of study goes into it.

Don't start filing on the needle or jets, that will throw off the adjustments when you do find the source of the problem.
It sounds to me like you have a clog in a passage somewhere. I would suggest pulling the carb off and taking it apart, soak it, then brush and blow out every little hole you can find. That is the only way to know for sure that all passageways are clean and clear.
A few hours work are well worth it.

Hey aloha girl,
Lancer is correct- You will have to dig in the carb and diagnose before doing anything elce. The thing is that even without any mod, the Savage is running OK. You should not have to do any mods to make it run. Everything said and done here is to give it something more than the adequate running. If You have to push or pull to make it running adquate- You are having a problem. Knowing that the needle is in the lowest position from the factory and You can not mess-up without changing it, I'd say-it is not the needle.
If somebody has been in the carburetor before and he or she has not replaced stock parts, the only thing that comes to my mind is a problem with the slider diaphragm. You might have it pinched, or punctured, or You might have kinked spring.
Did You buy the bike this way or ot happened one day when You went to start it, or it was happening gradually?

It just doesn't seem to get warmed up enough to do it. Even with 90 degree weather out here.

It seems, that somebody has been messing with the bike before You bought it.
There are couple of possible reasons to have Your problem,
but the most likely ones are : wrong or partually plugged pilot jet, and problem with the slider diaphragm.
You don't have to remove the carburetor. You can access the float bowl and the jets from bellow and You can remove the top cover and check the slider, the diaphragm, and the needle just by removing the seat and losening the 2 carb clamps..

Is the float bowl attached to the carburator?
I'll go punch float bowl into the search.

No luck on the search. I'll check the Clymers manual.
Thanks for the help!

Is it the stock exhaust?if not you may have to rejet for exhaust. :-/

Title: Re: need choke instructions

The float bowl is where the fuel is stored in the carb. It is the bottom part of the carburetor and it is attached to the main carb body with 4 small screws.
About rejetting for an aftermarket exhaust- even with an aftermarket exhaust, the bike will run without rejet, but usually You get a poor performance.

If I'm reading this right I need to take the top and the bottom of the carb? If the slider diaphragm and pilot needle are on the top of the carb why does the float need to be removed? I can see in Clymer's manual that the jets are in the float bowl. So I'm basically checking both jets, slider diaphragm and needle to see if there is anything wrong?

First thing- remove the gas tank and pull the small decompressor rellay /the black box just above the carb/ out of the way.
loosen the 2 carb clamps so You can slightly twist the carb left and right, and take off the 4 screws that hold the carb. cover
pull the cover off and chesk the spring, pull the slider and chesk the rubber diaphragh for tears. After that if You want You can do some needle adjustments.
Be very careful when installing back the diaphragm and the spring.
The jets are in the float bowl. You have pilot jet and main jet. Check both - are they the correct size, drive a very thin wire thru them and make sure they are clean.
