oil is blowing back up through carb.

do you mean that oil is blowing up into the air cleaner?
run a compression test as mentioned, you can pick up a tester for about $30 and if you can change plugs you can run the test. if your intake gasket leaks your screwing up the fuel/air ratio and in turn your rig will run like crap. you can seach for a intake leak by spraying around it with wd while its running. run the comp test, post the numbers and replace the intake gasket then go from there. btw, does it smoke and welcome to the wire.


It doesn't hardly smoke but you can smell oil a little, and when you have the lid closed it starts back firing through the carb, and when you open it a puff of smoke will come out blueish color. I was gonna work on it today but it was raining, and currently our garage is full so no go. I need do need to check the intake gasket though, and run compression test.
