Looks like Maxtowers has not been here since Mar 31st, 2014...

So,... you won't be able to contact him from here...

29mm ? is that the float height?

max had a collapsed float, which threw off his float level.

If you have similar issues, check your float level.
easy way is to attach a clear line to the bottom of the carb drain and open it. with prime on, the gas level should rise to just under the gasket.

this is the situation

-black\rich spark plug
-bike run only 40\70km after this stop and don't start if i don't put in a new spark plug
-I never use start choke for start the engine when is cold
-the bike is original and all jet carburator are clean and original
-float is not damage (I make a test in water)
-vaacum line have not gas when the bike not run
-if I run with on or reserve position in petcock without vaacum line the motor try tostop
-if it's in prime without petcock...always run
-today I make a test: the bike already run with air/gas mixture screw all closed!!! and I the engine don't stop!!! I think is not correct...

question:

how the vaacum line work when the engine run???

what kind of other test I can do?

Is my problem a problem of rich gas/air mixture?

my carburetor code: 24B40 E241 tell me some info of original jet measure

thanks a lot!!!

Reply #8 - 07/31/14 at 05:55:05 It sounds to me like you have a bad petcock, and it is letting fuel enter the engine through the vacuum line. Plug the vacuum line on both ends, set the petcock on PRIME, and ride it for a while and see if the bike runs correctly. If so....you need a Raptor petcock. Dave

I have one that I've used to set up vintage MGs

The colortune would be just about worthless on the Savage. The plug is buried under the fuel tank, down in the cylinder head.....if you do manage to catch a glimpse of the plug....it will only show you what it going on at idle...as you can't ride and observe the plug while you are riding.

If you really want something worthwhile, you need to weld an oxygen sensor in the header pipe, and use a meter.

ok dave...I make your test this evening...but tell me:

-what's the difference from original petcock and a raptor petcock?

-with the raptor petcock I have always to connect the vaacum line?

-and in last...if you're right...why I don't see some gas come out of vaacum line when it is disconnected?

thanks!

The Raptor petcock is manually operated. You must turn it on by hand when you want to ride, and shut it off when you are done riding. There is no connection to the vacuum port with the Raptor, and you need to plug that port on the side of the carb to stop the air leak.

Without the engine running - there is a spring that closes the diaphragm and stops the fuel flow....this spring will work even with a hole in the petcock diaphragm and will shut the fuel flow off. When the engine is running and pulls the diaphragm open - it can leak fuel into the vacuum line if the diaphragm is leaking.
