71MonteCarloMD Posted December 24, 2019 Share Posted December 24, 2019 After replacing distributor with Petronix which started Monte quickly on a cold start. Drove out of garage in reverse, no issue. Letting it run for a few minutes then put in first gear to move back into garage it shuts down - it started up again without any issue, put in gear again, it shuts down again. then almost didn’t get it to start but got it running. Had to press on gas to Keep it running after putting in gear. my 4bbl Rochester carb was rebuilt by local shop 2 years ago that improved with braking and moving forward at red light. am I experiencing vacuum issue? If not, what am I experiencing? And what solution to resolve this? Quote Link to comment Share on other sites More sharing options...
Rancid87 Posted December 24, 2019 Share Posted December 24, 2019 If you didn't tighten the distributor hold down enough the distributor could have moved. I'd get it running again and adjust the timing. Quote Link to comment Share on other sites More sharing options...
Rob Peters Posted December 24, 2019 Share Posted December 24, 2019 Is it possible your idle solenoid.... also known as the anti-dieseling solenoid, is set properly. If the idle is set too low, once you put it into gear it may shut off. I also agree with checking the timing. rob Quote Link to comment Share on other sites More sharing options...
1970mcss Posted December 24, 2019 Share Posted December 24, 2019 Ditto on the timing, did you possibly pull off the vacuum advance hose? Quote Link to comment Share on other sites More sharing options...
71MonteCarloMD Posted December 25, 2019 Author Share Posted December 25, 2019 I haven’t checked timing after replacing the distributor to electronic, will check. which hose is the advance hose? Quote Link to comment Share on other sites More sharing options...
cny first gen 71 Posted December 25, 2019 Share Posted December 25, 2019 Ditto on the timing but did you replace the wire from ignition switch to coil? Pertronix requires 12 volts as opposed to the points which only required about 6 volts at start up. It should tell you that in the instructions. The orig. Is a resistor wire and needs to be replaced with regular wire. At least my petronix set up is that way. Quote Link to comment Share on other sites More sharing options...
71MonteCarloMD Posted December 25, 2019 Author Share Posted December 25, 2019 Yes, I replaced with 10 gauge wire from fuse box (ignition) to the coil. if I remove the advance vacuum hose, what should happen? Quote Link to comment Share on other sites More sharing options...

It will change idle a little but shouldn't cause it to stall. Check and reset timing that will probably help. Quote Link to comment Share on other sites More sharing options...

71MonteCarloMD Posted December 29, 2019 Author Share Posted December 29, 2019 Thanks all as I was able to tune it up and felt the engine runs more smoother! And no longer shut down when putting in gear! one thing I noticed when shifting in gears, I could feel entire car shifted in gear, is that normal? This may be that my timing gun broke during the adjusting timing as I made my best guess based on my feeling on the engine running? Quote Link to comment Share on other sites More sharing options...
Rob Peters Posted December 29, 2019 Share Posted December 29, 2019 Idle may now be set too high if you can feel it that much when shifting. rob Quote Link to comment Share on other sites More sharing options...
