Six Pack issues and rebuilding by tommyg29

3 minute(s) of a 193 minute read

Had a spare 30 minutes this evening, so another update. After letting er idle a number of times for a few minutes each over the past few days, just tonight the smoke MAYBE started to clear.

But, it seems to only idle about 4-5 minutes then it abruptly shuts off with a big wheeze/cough out the center carb. 

BTW, the secondaries are now fully connected up, fuel, linkages and vacuum tubes.

Also, whats with the vacuum less than 5 inches?

Could this be from a leak or uncapped opening? I checked everywhere I could. Maybe because I removed the choke assembly? I am pretty sure my numbers used to be in the 13-15 range.

Yippee 

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.
