Post by: huskerrob on September 27, 2012, 10:18:42 PM
Does anyone have the proper fuel line routing? Mine is scuffed up so I cant see it.

Not sure what model you have, but line comes out of the y piece wraps around the carb bracket on top of carb, and goes under the two inlet lines and back to the tank (popcorn)

nope she sure hasnt. I have narrowed it down to the fuel line or petcock. I just replaced the fuel line and routed it properly. It ran fine on prime but in the on position it died like it was out of gas... Soo I think I need to replace the O ring in the petcock put I am not sure.

Nope its an 85 but I believe I don't have the stock petcock as it has a reserve. I have heard that replacing an "O" ring in the petcock will fix this. Will try soon!

no worries, do you have a pic of the tap , also if its still vacume operated make sure the vac line hasn't got a hole in it and sucking air

If it's the stock petcock then you've either got a bad vacuum line or the diaphragm is torn. 
It has 2 positions:
ON flows fuel ONLY when a vacuum is present (i.e. when the engine is running)
PRIME flows fuel all the time.  Prime is NOT a reserve, it only bypasses the vacuum function.

Replacing the o-ring will not help fuel flow.  A bad o-ring causes the petcock to leak fuel (into the fuel line, not on the ground) when there is no vacuum present.

Its not a stock one as it has the reserve. It seems to be running ok (Not Great) now. For some reason in order for it to idle properly I have the idle mixture screws one screw out after cleaning my carbs.
