Here is the problem. i bought, well i got a '86 crx because i found one that they said had a blown motor and it wouldn't turn over so before i gott it i looked it over and found out that the plastic valve cover had melte down onto the rocker arms and ceased them. Well I got it and I had to snap off the valve cover and it took me three hours to very carefully remove all the plastis and free up the rocker arms. I got inside the car and tried to start it up but it wouldn't catch. It turns really freely but just won't catch. it is the HF model, thus being carburated. and while i am triing to start it it puffs white smoke out of the carb but wont start. what's the deal?
