White smoke and rarely starts?
 

Ok so i am having trouble getting my 1985 firebird started, it takes alot of carb cleaner blown directly into the carb before it even gets close to starting. Most of the time i wont even start, but 10% of the time it does, and when it does it blows alot of white smoke. If you give it more gas, it blows more smoke. If you guys have any ideas on what i could be, i am at loss. I had people tell me it could be head gaskets, but my oil isnt milky at all.
Thanks

sounds like a head gasket, have you pulled the plugs and looked at them? also you might want to do a compression test. you may not have oil in you coolant. you can also us a radiator pressure tester and check for the leak that way.

How can I do a compressions test

Re: White smoke and rarely starts?
 

with a compression tester

Carb cleaner typically burns white.

when it does starts to run, ill have it run for 10-15mins and it will still burn white, the more gas i give it the thicker the smoke
