2 Stroke hard starts
360Deluxe

I own a 69 Subaru 360 Deluxe Sedan. It's a 2 stoke 360cc engine. Living in the desert the engine compartment gets pretty hot which causes a hard start if the engine sits after its been running. I've wrapped the muffler and installed a heat shield to prevent as much direct heat to the carb. Could I install a hot start switch like they have on 2 stroke dirt bikes and snowmobiles?

Sure, you can use one. I expect some fabrication would be involved to adapt one intended for another application.
Just make sure it does not open (switch on) after the engine is running or you will burn pistons for sure.
However...... are you sure you do not have vapour lock in the fuel line, or are boiling the fuel in the bowl?
Also, have you tried another ignition coil, in case it's over heating or defective?

If it is vapor lock in the fuel line or boiling of fuel in the bowl what would be a cure for that. It's a gravity fuel line no fuel pump.

You have a steel fuel line now, right?
You can get a special wrap for fuel lines which serves to insulate the line or do this home made job:
I have had some success by using rubber fuel line. Get some line which is large enough to slip over the steel line. You may have to cut the rubber line down its side so it can slip over the steel line. Then wrap the line in aluminum foil and secure with tie wraps.

The fuel line is rubber not steel. I suppose wrapping it isn't going to hurt. Thanks I'll try that and see what results I get.
