Dave built me the carb that was supposed to be the best of the best, all the tricks. After replacing the accelerator pump and spring, I ran the carb. I tuned the carb in to a good a/f, which was one metering rod and jet change. I then built the same number carb, using all the parts from Dave's (Metering rods, jets, needle/seat, pump squirter) All I did was massage the airways alittle. Mind you my first ever rebuild of a thermoquad, that carb picked up a tenth and 1 mph. So the same tune, my homebuilt thermo beat the best of the best. In a heads up class, 1 tenth is to die for. Maybe Dave could have found the tenth, don't know, but I was pretty disappointed.
Now hopefully that is over with...
Has anyone else experienced tuning with the air door that actually results in e.t. change? I understand if you weren't close on it, you will pick up. But the minute changes that affect a/f, does your car actually respond to it?
