Tuning issues when using carb restrictors?
I am using a os speed carb on my engine and i am wanting to run a 6mm restrictor on it. except it is making tuning very difficult. is this a common thing when running small restrictors? when i was running a 7.5 in there i wasnt having these problems but the engine was a little thirsty.
os speed carb go tech restrictors, nitro juice 30% new gen fuel, sts 3 port mill medium plug
