I've had an off-idle stumble with my GTX since i got her, and have had a lot of "advice" on what to do to get rid of it. It would stumble and die at stop lights and stop signs if i sat there too long and i would die going up my driveway in reverse (longish, prob 4* upslope from garage to house). it ran great cruisin' and foolin' around on the streets, but damn thing wouldn't stay running @ the lights!!
So i did some research on my own, and with help from a friend who didn't reply with "you should get rid of that Dodge and just get a chebby, (like the rest of us)":mad_6: IT'S A PLYMOUTH DAMN IT!!! Sorry dodge guys :tongueflap:
Anyway, i digress...so we started with the IMS (idle mixture screws) on the carb (800 eddy thunder) and did a little fiddlin'. Holy crap!!! it's like a brand new car!!! :th_krazy:
Now, i know there are A LOT of variables that come into play with my question, and i will try to answer them as much as i can. I have a limited knowledge of carbs and timing, but my buddy explained it to me, and it made sense, so we went for it!!
We re-set the IMS by screwin' them all the way in, and at the end, we were about 4 1/2 to 4 3/4 turns out, with the idle speed @ 850rpm (no load), and 650rpm (w/load). I think she may need a bump up 100 rpm or so (no load), which i will have to reset the IMS again anyways??? either way, my actual question is do y'all think 4+ turns is too lean or will hurt the motor??
I know, there's a lot up in the air here, but i would much obliged, if anybody could offer sum help!!! :grin:
