Title: fuel in oil
Post by franch on 09/08/08 at 08:05:46

Ok I am confused about how gasoline can leak past the bowl into the crankcase.
I have been running my savage with the petcock on prime while i await a new petcock.
i haven't been shutting off the petcock figuring the carb float does the job of stopping excess fuel.
what are peoples thoughts ?

The floatneedle does not close properly when the carburator is at an angle e.g. when the bike is on its sidestand. Some fuel will evaporate and if the inletvalve is open the fuel can leak past the piston ring into the crankcase. This may sound silly but has happened to some (on this forum) >:(

The float valve does the job most of the time. However, someday if may fail. Do you feel lucky punk? Now you may ask yourself, it shutoff yesterday, did it shutoff today or not? Go ahead, leave it... :o

Do you have the vac line capped off?...If the vac diapragm in the petcock is leaking, there is nothing to stop it running down the vac line and into the engine.

I done got them all worked up over texting and exploding rear tires. They will likely be downright unruly for a while .... jest ignore 'em.

=====================

Now -- if you REALLY feel lucky, punk ...

I'm going back to the mountains in October when they shut my plant down for another week of unvolunteered vacation.

Mountains will be BEAUTIFUL, pace will be sedated (valium, I suspect)

Your odds of going horizontal are only 50%, so it isn't suicide, exactly.

Just good 'ol boy-fun.

What 'cha say?
