I have a 1992 b2200 with a Weber carb, she set for about 2 to 3 years. I finally got it running after rebuilding a thorough cleaning of the carb. If you roll into the throttle it'll rev to 3k anything after that it starts acting like it's got a bad misfire. From idle and even up as far as 3K you try to throw it to full throttle it'll just die out like as if you cut the truck off. The truck ran and drove fine before I let it set and I'm lost don't know what to look at anymore.

 

Take off the air cleaner. Start engine and rev up high, see if the secondary is opening. If not, try aerosol carburetor cleaner on the linkage at rear of carb, assuming that you re-assembled it correctly (did you actually do a rebuild or just attempt to clean the inside?).

When was the fuel filter replaced last? Hopefully you don't have rust/debris in the gas tank clogging the fuel "sock" there.

 

This weekend I even went as far as to take my air hose and apply air into the gas to force gas up to the engine bay to check for holes in my gas lines and everything is good. Now I've noticed when the secondary opens (not sure of it should) I don't see any gas spraying out of the ring piece above the butterfly like on the primary.

 

So this morning I grab a water bottle and drill a hole in the cap, then filled it with fresh gas. I'm starting to believe that there was some left over bad gas in the tank, because now I can roll into the throttle all the way to the floor and she will carry the RPMS

 

Did you drain the old gas out of the gas tank before you started the truck? If not, whatever was in the tank got sucked into the fuel pump & the carb bowl.

On the secondary side, you typically won't see fuel squirting into the venturi like you can see on the primary side, when you rev up the engine.

Look down into the secondary side, with a flashlight, when you rev the engine up.....if the throttle plate is opening, and the engine doesn't falter, then the secondary side is getting fuel. Keep in mind that the 32/36 carb has a vacuum secondary......it will only OPEN in a low vacuum instance......like a quick rev, or when flooring the gas pedal while the engine is under a load.

 

I got great news! I just drove it around the yard and even floored it. She smoked the back tires real quick, granted I don't have a bed in it right now 😂😂😂

 

Good job! Glad you got it figured out now!
