To answer drewsky question, I didn't change the oil. Even though i should have. I'm leaning more to the leaking valve seals though. Or the carburator. It is a sort of grey smoke it's not pure white.

 

well learn out the carb alil.....you might think I'm crazy but this has been known the help..get a 32oz cup on water..rev the engine to like 1500 pour the water slowly down each of the front barrels pour it til it starts to stumble then rev it up to clear. do this til the water is gone..watch the carbon fly out the exhaust. I have ran as much as a 1/2 gallon thur

 

Ok, it's a 2 barrel, but it doesn't matter. I do have ALOT of carbon in the motor. I never heard of doing that but it's worth a try. Thanks

 

I've never heard of that either. You can do the same thing with carb cleaner.

 

Yep, I've done that with a pop can full of water, it will work on a carbeb car like this one. Make sure the rev's are up and don't use too much water......
