Default Heating with a heat gun?

What part of the engine do you heat with the heat gun?

The case is where the piston and sleve are and thats what you want up to temp before firing the engine.

Default Be careful

I use a hot pad (from the kitchen) to put over the carb and fuel lines so I dont melt them. Also dont shoot the heat for too long in any one place. It can get really hot really quick and could potentially warp and or screw things up. you want to keep the heat gun movong around all over to try to heat evenly. I heat my JP engine til about 180º-200º F before I fire it up. I then let it idle for a few minutes to begin the heat soak process
