ok so i dont know if its running rich or not but i put a bit of stabil in it since i still have the 2 year old gas in the car to stabilize it while it in the yard till i can get it road legal to gass it up.when i rev it it blows clouds of white smoke and once it goes back to idleing the smoke dies off to a little puff here and there right at the tail pipe. it is 56 degrees or so out right now so that may be the puffing. any ideas on what it might be?

 

If the smoke is white check your coolant level. You may also want to go to the auto parts store and "rent" ( usually free) a pressure tester that goes onto the radiator cap. The pressure should remain constant when pressurized.

 

I would suspect the 2 year old gas is playing a BIG part in your smoke problem. If possible, throw like 5 gal of new gas (if its not gonna sit for another 2 years) and see if it clears up. Sta-bil `does what you said, stabilizes the gas, but only in new gas (as far as i know of). I wouldnt use it in already deteriorated gas. New gas has all sorts of detergents and stuff in it so it doesnt last. For example: if i dont put sta-bil in my mower equipment when in put it away, it wont last the winter, it'll gum up and i have to clean all the carbs in all my equipment.

Just incase i'm wrong (which i tend to be), keep an eye on the coolant level. The head gasket could be blown, the intake manifold gasket too, or worst of all, the water jacket portion of the block could be cracked. An easy way to check to make sure: take the dipstick out, if your oil turned a milky color/consistency, you're getting antifreeze in your oil!

 

its the gas i put i guess 4 gallons of gass and its started running without smoke
