Will do, LG why is it that the book and the rebuild kit settings are wrong?

I adjust the idle to see 13v on the battery with a warming up engine (so manifold heater is on) and headlights on and fan in high

It ends up being around 800-850.

It will idle lower in hot dry air than in cold wet.
Don't trust the OEM tach either.......

The volts shown depends on the condition of the alt/battery and temp.
BTW: You want at least 13.5-14vdc for a good 'rebuild' charge after start up.
I have more faith in my amp gauge than the volt gauge(I have both).

I use my fluke DVM on the battery posts and I have 14.5 driving down the road. I also have the cigarette lighter wired directly to the battery so I also use the below volt meter too. Its as accurate as my DVM to two decimal places.

I was using shop tach, so it's fairly accurate.
I never gave thought to the voltage draw or such, so I should look at that, check it now out of curiosity.
At 650 it had a slight misfire or stumble, though never stopped. The emulsion tubes don't leak.

Wonder how the OP is doing?

UPDATE: so i messed around with the float for a few hours adjusted it down and even up, no change. I even went and got gas thinking it might be running out, no change. Finally I went and disconnected the EGR... Guess what problem almost completely went away. Now I need to pass emissions so I dont want the EGR out of the loop if its going to be doing me some good, but I cant have it running the way it was.

Im getting about 10 in HG at the EGR with the engine at high rpms, maybe this is to much and I need to limit it down somehow?

BE CAREFUL! Don't lose the acc. pump spring, or the 2 'e' clips.
Now you can start the engine and see where the float level is.
See the two cut-outs at the top of the acc. pump shaft? You want the fuel level to the middle or just a bit more on those cut-outs.
You will need to plug the vac. line to have your eng run 'rite'.
Did you ever order the FSM that you REALLY need to have?

THe actual metering of the EGR is done with holes sizes. Maybe you need one with smaller hole size.

someone just posted a list of EGR valve part numbers and hole size...
