I have not checked the secondaries on the carb that is on the car, so I am not sure if it has jets or a metering plate, just started with the primaries to get the car running better. Drilling out the #61 jets had a major improvement already (drilled them out just enough to see a visual size difference, nothing drastic). My question still is...if an engine is set up with higher compression and a bit of a cam, is a bit of a stumble/miss while at low throttle while driving normal? Timing is at around 30 BTDC which is where it seems to run the best. All plugs are good and firing, vacuum advance on the dist. is working, my only thought now, if this is a problem, is that there may be an intermittent issue with the coil......Again, the car seems to be running much better now, but the slight stumble does seem right to me.
