Hi Harry,Good job fixing your vacuum leak. I assume no others? I’m sure folks will have good ideas, but I’ve found that the choke setting on the carb is very important. Also, check the spark plug wiring for good connection and proper firing order.If you set the timing with a vacuum gauge (need the procedure?) and then check with timing light, the light can give an indication of whether you have slop in the timing chain or have jumped a tooth. Give some throttle by hand and watch the timing mark - it should not hop around, assuming a good operating light…There are other things too but that’s a start?R,daveSent from my iPhoneOn Jun 10, 2022, at 2:36 PM, Harry Torgeson <torg66@xxxxxxxxx> wrote:I have a mechanic who has not been able get a smooth idle for me, I replaced the distributor with a pertronix 2 times, put back original distributor runs better, put in new Edelbrock carburetor, fixed intake manifold vacuum leak, also ammeter needle jumps when rough idle occurs, was worse with pertronix. Thanks in advance for any ideas on this issue.--Harry Torgeson971-221-4699
