Sounds a bit like vapor locking but could be a heat sensitive ignition component as well. You're not running ethanol based fuel are you ?? beer


Yes, actually I do tend use ethanol


Ethanol based fuels have a lower boiling point than non ethanol fuels and can wreak havoc in older carbureted vehicles with the temperatures we've been experiencing. \
I would start by getting it out of the system ASAP. Other changes may also be required if it is vapor lock and changing fuel does not resolve the issue. beer
