Checked timing and plugs today.
Timing mark was was down on the strap.
Idle was way up, with a hard shift into gear.
Backed curb idle WAY down, Reset initial timing at 15. Timing still coming in WAY up at 3500+.
Changed to the silver springs. Reset curb idle and initial timing to 15.
Now all in at 2500, full advance 36 deg.
My distributor got sold on a customer's engine and was replaced with a new MSD unit and I did not think about the curve in the new distributor....
The new distributor was maxing out at 28 all in at 3500+
Now idle is crisp and lumpy, temp gauge sitting at 185. No more slam into drive from neutral.
Gonna have to re jet again and tune to the new timing.
