My 98 350 big bear just died when right before I loaded it on the trailer it started back up and i got it on the trailer and it never started again. I have a climber manual and checked about everything logical. It has a spark, and its getting gas. I was thinking maybe something with the compression. I can hold my finger over the spark plug hole and cranck it, it doesnt blow my finger off. or maybe the timing, any way to check that? maybe the spark just isnt hot enough. Help
