another thing that comes to mind when tuning tq`s. the carb must be vented anytime it is under full-throttle. if the vent is not operative on your carb, it will be impossible to tune...
Hmm...OK, worth a try, I have the vent currently plugged with a cap on the vent tube only because I didn't feel like running a vent line to the purge carnister (one less vac line in the engine bay, kept it cleaner), but I had never realized this might be the implication. Good call!!!
