Toyota Carb Problems

[cumminsdzl]

Well, for the first time since last August, my Toyota pulled itself out of the shop this morning about 1 am. The 22r has been completely rebuilt, new clutch, rebuilt carb, redone all of the vacum lines, added power steering, welded the rear diff, got the swampers on, and several other small things. Im pretty excited to say the least.

Heres the bad news. When we got it fired up it idled great for about a minute, then started to sputter. You had to keep your foot on the gas to keep it running. We have been adjusting the settings on the carb using the service manual and everything is in spec. It seems as though the problem is related to the choke, but im not a carb expert. I've gotten it to run, but it has to idle at about 1500 rpms. You can tell its running to rich, bad gas smell out of the exhaust, and stumbles when you get on the gas hard.

I think there is an idle mixture screw that has a plug over it from the factory, or so i have been told.

Sometimes the truck will crank right up, other times its slow to turn over like it has been flooded. im having a hard time diagnossing these problems. Any help would be great.

Not sure on the carb, but when you say sometimes it's slow to turn over, my first thought is whether or not your timing is advanced too far therfor making warm starts harder?

Remove the air cleaner, look on the side of the carb. There is a cover held on by 4 skrews that has a vacum line on it, is there gas in that line? If so, replace the alititude diaphram, fire it up and give it the messican tune up. Messican tune up, rev it to 3~4 grand and choke it out with your hand over the air horn a few times, dont let it die. This actually will pull a lot of the garbage and varnish out of the sir bleeds and such.
