I have a question. My husbands 94 Mighty Max wont start. He tried and a puff of smoke came out and now nothing. He noticed that there was oil on the spark plugs. What do you think the problem is. Please help me.

 

sonds like his vlave guides are leaking and or his rings are fried he might want to try an engine cleaner runs about $60 at your local jiffy lube or run a bottle yourself but read the directions carefully. try a cleaner called seafoam
