I thank you guys in advance for all the good information that is up on this forum. My F2 was running ok, slight hesitation on the low end, and at full throttle there was some pulsating/blurps of power. I noticed this after putting a stock pipe on because the old aftermarket carbon pipe was shot. So i figured it was my carbs that were dirty so took off the airbox, engine was off, sprayed in carb cleaner and hasn't started since, its been 4 days. took my carbs off yesterday, jets are spotless, no vaccuum diaphram cracks or apparent problems, i didn't find or take out the pilot screw, but it looks like there is gas coming from where the manual says the pilot screw should be. not dripping but slowly forming a drip. Engine has consistant spark on cylinder to far left, didn't check all of them. and backfires really bad. It started backfiring after i sprayed in the carb cleaner the first time before i took off the carbs and cleaned them. Your advice would be much appeciated. I hope this all makes sense. Thanks guys.

 

your positive all your hoses are connected properly?

 

You might be running too rich now, if your carbs are jetted for an aftermarket pipe. It's probably flooding

 

hersh go answer my trans question on the thread i believe located below this lol.

 

I think all the hoses are correct, to my knowledge. When i pulled a plug out to check the spark, it was wet, so could be flooding. if i pull off my pipe, and have just the manifold connected could that be a too rich test? As for hoses, vaccuum and gas connected to tank, hose from airbox to carbs, carb breathers fine, header to airbox, are there any i'm missing?

Shardoflard, i didn't mean to steal hersh from ya.

 

Try putting the old pipe back on, and see if it will start... Pull your plugs out and let it sit for a couple of hours to allow any residual fuel in the cylinders to evaporate.

 

i think you might've messed up the sync. of the carbs

 

I will pull the plugs and take off the stock pipe and see what happens. weird thing is it ran fine with stock pipe until i sprayed the carb cleaner in. I didn't turn any sync screws or pilot screws, could the carb sync still have been screwed up by just the carb cleaner spray?

 

It's probably just flooded with carb cleaner, use compressed air to spray out the cylinders

 

Flooded and then fouled plugs....you didnt gas it while it was choked did you?
