vacuum gauge to solve idle issue
So resurrecting old thread from last year. Rebuilt the factory Carter 4295S. Installed it, choke unhooked.
Pretty much fired right up. Idle mix screws are set close. Idles in park around 750 rpm.
1st test drive was not bad. A definite improvement but still "surges/stumbles" More so with steady throttle. Accelerating makes it go away. Temporarily.
Came home checked cap and rotor. Both looked good. Module and reluctor gap looked cockeyed. (See pic). They didnt look pparallel to each other. MP elec ign instructions say .008-.018" gap. I set it to .010" ar the tightest (bottom) spot.
I can move the module ever so slightly even when tightened down but not enough to align parallel to reluctor.
Dist bushings se tight, shaft appears straight. No wobble.
When I removed distributor it looked like there was oil on the inside but it could have came from me turning it upside down. I thought maybe a crack in distributor body that allowed oil to seep in?? Couldnt find any cracks.
Cleaned it and reinstalled.
Another test drive. Absolutely horrible.Almost constant surging, not so much at idle but at cruise and acceleration.
I took a few pics and video. I'll try to get them posted.
Thanks all.
1st pic is alignment issue
2nd pic is where I saw oil?
