3.8 dualjet part throttle hitch

[fleming442]

All this talk of a dwell meter with no specs to shoot for or how to hook it up....
I have one my dad left me; never used it in 30 years of tinkering with cars.

one clip here one clip there....... it doesnt matter where

in 30 seconds the problem would be solved with a piece of emery board.

Like this is some type of new issue with a carb just because it has "electric" going to it.

Dwell meters are easy to use. Black clip goes to any ground, and the green clip goes to the green dianostic plug which is normally not plugged to anything. set the meter to dwell mode and only use the 6 cylinder scale. On is lean and off is rich. A low dwell number is a rich command, a high number is a lean command, 30 degrees is the middle or half of 60 degrees which is what you want. Only read the dwell after you make an adjustment and put the air cleaner lid back on and let it settle down. It isn't hard to do. If you are not getting any responses from the adjustments, then there is a problem. If the computer is stuck rich for an example, you have a lean problem and vise versa.

somewhere i read that there are two IABs, one with writing on it that is set to a certain height and then to adjust dwell you turn your idle mix screws. and then there was the type that you set your idle screws and adjusted dwell with the IAB. something about having a letter on the top ment you left that one alone, which is the one i have. as i stated in my first thread my concern happens with high load and about half throttle. im not getting an off idle stumble. and i do ahve a dwell meter but its about 250 miles north of me at the moment with all my other tools. i did turn the iab in an 1/8th turn and so far i have no had any issues. the only way i will know for sure will be once i head back home.

and a month ago i checked dwell once the temps got down and verified it was still at 30.

Hell, I'd live with that! I never even touched mine, and put 30,000 on it.

Manually depress the accel pump plunger and see it it pops right back up. If it is slow, the seal has swelled. Had that happen to me once.

Yeah, you read right. Factory shop manual is one place. What I was saying. Mine has an L on it.
