I have a Gilson GT14HE that is overheating and I'm at a loss for what's causing it. It seems like it overheats to the point that vapor lock occurs. I've changes the plugs, checks the flywheel for debris, check to see if the muffler if blocked, checked to make sure the gas cap isn't plugged and maybe some other things that aren't coming to mind. I'm ready to take it to the shop but thought I'd see if anyone else has a thought to share first...

All the "tin" on correctly? Timed correctly? Good/correct motor oil?
I may be grasping at straws here, but that is what comes to mind....Let us know what you find out.

Low coolent (if radiator equiped). Cooling fins free of debres (under the shrouds), Fuel mixture (carb adjustment) and timing (if it is adjustable) are the main causes of overheating.

Could it be running lean. That will cause the engine to run hot!

Haven't had a chance to check any of these things out yet but I will as soon as i can and let all of you know.
How can i tell if it's running lean? Also, how do I check the timing? Thanks.

Sounds like it's time to look for a mouse house in the cooling shroud. Also route your fuel lines away from any high heat areas of the engine.
