engine sputtering

[dfcruiserguy]

the engine is all of a sudden sputtering, sometimes it won't start and other times it won't keep running and it smells strongly of gas up front. I drove through a creek a couple times today, could water have gotten under the distributor cap and this be the source of my problems? i'm not sure cuz it ran fine after driving through the creek. Could it be a carb issue?

Blow out the charcoal canister with compressed air. Detach the 3 hoses from the top of the canister. Plug the two hoses that run towards the firewall. Blow compressed air at around 40psi into the hole that the elbow hose runs into. See if that helps. It seems like anything to do with the charcoal canister ends up with strong gas odor.

A good check is to open your gas tank cap. If there seems like a crapload of air pressure coming out, your canister is clogged and the compressed air trick will help.

Good luck.

Never let your fuel tank build up with pressure. I washed down a 40 motor by pressurizing the gas tank. It siezed about 3 seconds into starting it up.

Course, I am still using the motor

Also check the Dist. if it is corroded you have a problem

hmm, well, normally it the gas tank lets off alot of pressure, i'll go check and see if it does it when i take the top off, but as of late it hasn't had any pressure, which surprised me. lets see what that gas cap does.

 

[dfcruiserguy]

nope, no pressure on the gas tank

what if the highpitched whistle kind of sound is coming from the block, because i heard a dull knocking near the piston closest to the firewall and when the rpms go up the high pitched noise starts. and this somehow cuasing the sputtering?

 

[dfcruiserguy]

just drove it up the street and back, no sputtering, may have fixed itself, whatever it was.
