Default 1990 LT80 won't start, gets gas and coils are good little spark

We have a 1990 LT80 i replaced the primary coil and checked the secondary. Both are good. I am getting very little spark and i can get it to fire once in a while when i put gas in the cylinder can someone sugest something?[img]i/expressions/face-icon-small-disgusted.gif[/img]

Check the compression. From past exsperiance (sp?) I've found ours needs around 90 lbs to start.

ditto asfasasu. low compression is often the problem when you've ruled out everything else, and it's easy to check with a compression tester. putting your finger over the hole isn't good enough.

Good advice given.
Putting gas in the cylinder points toward compression.
We'll go over the weak spark once you figure out the compression.
