Eddy 1405 tuning advice

Eddy 1405 tuning advice

So not much time to tinker with 2 grandbabies for the day lol, but I was able to bump timing up to 18, which increased idle speed. I backed out the idle screw 1/4 turn(closing up t-slots some). I then messed with IMS screws. I know a lot of what I've read says to start at 2 or 2 1/2 turns out, but I see MINIMAL change till I hit around 1 1/2 turns out(approx).
I got max vac at 14" in park, 650 rpm.
No helper, so limited with what I can do. I'll see I'd the bride can resist running me over tomorrow while I'm under the hood.
Drove great tonight, not one bog surge or backfire. My thoughts are the idle quality(in gear)is low due to 340 cam in 273....
Well to raise up rpm I either increase timing or increase idle screw, which opens up the T-slots causing the symptoms/erratic bs.
Thoughts?
Hope to drive the pi$$ outta it tomorrow and get some more readings.

Did you say you also had a 1406? I wonder if you should pop it on there just to see if there's a quirk in the 1405. 1406s come set up a little lean, so if you have a set of 7347 or 7147 rods, you may want to pop them in. If not, you can still do a comparison.

:thumbsup: He should check the timing while he's at it.

Kick the timing back up to 16, then check in gear.
I set my initial in gear
