that makes a lot more sense as the tank area does appear to be very hot. I have removed the cap to see if it was stalling due to vapor lock but I didn't see any bubbling at that time or very high pressure when cap was removed.

so you suggest to run a higher octane best I can do at the pump here is 93 which I run 87 now. any other suggestions other then removing tank and heat wrapping as much as I can? also this is early spring so not even heat of summer yet. if this is not a good machine for this type of work I need to trade it on another asap.
