Took it to the gas station tonight for the first time since last year.
Put 8 gallons of 93 Chevron in it.
I have been idling it for 5 minutes at a time, and it still cuts off after about 5 minutes for some reason.
Blowing a lot less smoke, but still a tiny bit.
Vacuum reads about 10 inches now at 1000 rpm, and goes up to about 20-22 at 3-4000 rpm. It seems fairly steady at a given rpm, so it isnt fluctuating or jumping around (which I think would indicate valve or ring issues)
Also, I still cant seem to get it to idle steadily, as it warms up it seems to want to start idling about 1500-2000 rpm, and then when I turn the adjustment screw down it will idle normal, but then next time I start it a few minutes later (while still warmed up) it will bog, so I have to turn the screw in again to get it to get the idle up to around 900-1000, and then after it runs awhile longer it sometimes start idling above 1500-2000 rpm again.
During my first drive around the block yesterday it was warmed and idling normally, but when I drove it up to about 3000 rpm it wanted to stay up there. I drove it home and pulled in the driveway with it "idling" about 3000.
At least today it ran better, so I am making progress
Still playing and trying to figure this thing out.
