    Have you taken compression readings recently?

    On your carburated engine slight off timing could certainly be your problem. I would ask who ever did the chain to recheck it. When you are satisfied that it is timed correctly, we can go into other possible solutions.

    hello jackc---i did the chain job--timing was set to specs 6 degrees before tdc after job.---but when problem persisted i advanced timing too? ( i loose the mark before scale marker -- i just have plain ol timing light ) not much maybe 8 degrees just to raise rpm-- then rpm reset at idle screw--should i put everything back to specs and go from there?--after i do that any more thoughts---could this be electrical---it has new dist. ballast res. coil. ect.

    1978 only elec would be 12v to ICM* SO easy elimination of your elec concerns.

    Any chance of doing a vacuum reading...




    *ICM I can not remember if they called them ICM back then - 12v to ign

    ignition module-thats the word i was looking for last night -that has been changed----i have replaced a few vaccum hoses-when i smoother carb engine stalls out so i assume--i have no leaks---is that a good assumption?-- could it be the battery? i noticed while trying to jump start the ford--after letting it charge awhile--the second i turned the key the dodge would die

    I was suggesting confirming the 12v to ICM to eliminate electrical concern. Using a Jumper to confirm no loss of 12v.
    What does jump starting a ford have to do with this issue a DODGE?

    I asked about using a vacuum gauge and posting readings.
    >>> Covering the carb is not a 'ideal' test for vacuum leaks.

    Are you certain of the vacuum hose routing?
    Esp the feed to dist, choke ?

    PS: quadatherm? maybe a "thermoquad" - It was ok before R&R chain? did you adjust, tinker with, move anything?

    You went about this backwards. You never adjust rpm by moving timing AND THEN resetting at idle screw. You just answered your own question. Of course you need to put every thing back as it was. No wonder this engine is falling flat on it face when put into gear.

    I suggest you read this PDF very carefully and come back to us.

    http://tvmoparclub.com/files/tech/Mopar Timing.pdf

    I downloaded it here for your convenience.

    Always set idle before timing. Rule of thumb. See snapshot, then read the pdf carefully. Screenshot (115).png
