It was running so smooth after refreshing all of the gaskets and then all of the sudden it went back to not idleing without the choke and dying at stoplights again. Part of the back story is here:
https://forum.ih8mud.com/threads/confused-by-rough-idle.801259/
I spent many hours over the last few days searching mud threads for "rough idle", "idle circuit", "vacuum leaks", "idle adjustment". I know more but still can not figure it out.
timing is on the BB
vacuum off of intake is steady 17"
fuel is in center of float glass
I checked (disconnected and plugged) the big potential vac leaks without any change
the EGR is disabled
all other smog stuff seems to check out.
Now I am finally suspecting the carb and the idle mixture. The carb should be in good shape as I was frustrated a few years back and purchased a brand new one through SOR (maybe 50k on it). I can keep it running at about 950 rpm so I pulled the top of the air cleaner off and stared to play with the idle mixture. In or out did not make a difference, I took note of its original location and now have left it there. When I look into the carb I can see fuel coming out of the 1st main nozzle, I would suspect this is what is keeping it running. What confuses me is when I disconnect the solenoid valve it will kill the motor and I thought this was connected to the idle circuit.
Sorry for the long story, I try to read (search) more and post less but this is starting to get the best of me.
