It's a 70 cyclone, the performance model of the montego. I have a miss as throttle is added. The carb has been rebuilt, float levels are good. New plugs, wired, cap, rotor, points and condenser. I installed electronic egnition and that didn't help so I put the points and condenser back in. I've played with float level thinking I was running bordering on flooding because when idling if I shoot carb cleaner in the butterfly, it bogs down. Idle is fine. I have replaced fuel filter going into the carb and added one inline before that because of varnish plugging the auxillary needle. Its a 429 with an autolite 4300 carb. Any ideas? Haven't checked fuel pump pressure but when cranking, plenty of clear-of -debris fuel fills a mason jar. Please help
have the same problem?
