Engine runs rough and misses at both idle and accerlation

Hey Jason,
First,,WHY do you need to know where the screw is??? Why are you going to adjust it... it only controls the " idle to 1/8 throttle" part of your running engine... Is your engine is starting to run rough?? Please reply to me on here..I'll help you..

Clean the carburetor. That fixes 90% of rough running problems.

it should run rough any more then an idle the code is throttle safety signal voltage to high.a dealer should be able to flash the chip and as far as driving it whats it run like

fast idle start usually indicates an air leak somewhere.check carburettor bolts are tight and engine head bolts are tight.try that first

fuel issue. what year is it ?

If gasoline is left sitting for a while (2-3 months) it attracts water, which could cause the "smoke" and rough running engine.
Unless it is a 2 stroke engine, no oil should be coming out the exhaust. Hold a clean rag or a bunch of paper towels at the exhaust opening BE CAREFUL NOT TO BURN YOURSELF and than check if, whatever the rag or paper towels catch is oily. If it is a 4 stroke engine, and oil is the exhaust fumes, a seal inside the engine is gone and has to be replaced.

probably you have some worn parts in the carb.a rebuild kit would likely help.befofore you do that,you might try adjusting the air screw on the carb and check for air leaks where the carb connects to the cylinder head.

Carb is gummed up

sounds like its running rich. check your float height and then lower your main jet needle a notch
