Popping/backfire?
Shark Racer:
Nozzle drip tends to be an issue at idle. You could probably see it on the opposite primary from you while looking from the side.
gtome:
I guess I could grab some saftey glasses and have a look. not to dangerous at idle. But if i work the throttle it backfires through the exhaust and the carb. Spits up fuel.
Zac Agee:
double check your fireing order. carb shouldn't make it backfire out the carb and the exhaust that is timing relateted or fireing order. id be looking there caus you changed the intake and had the distributor out.
gtome:
I checked the firing order 3 times today! Im actually wondering if the plugs are so bad they are simply no good anymore. Im going to replace them and see if it gets me anywhere. It just doesnt seem to clear up anywhere in the throttle and it wasnt that bad the last time I started it.
rich ullsmith:
Try using a mirror to observe nozzle action.
