Horrible gas mileage and substantial lack of power.

Thing is, the carb that's on it was put on brand new by the last owner just a couple of months before I bought it and he only put about 2000 miles on the truck after that...

Sorry, should've been more thorough when reading your initial post - my bad. What was the idle rpm and start up like? There are only 3 screws that should need any adjusting on these carbs - air/fuel mixture screw, throttle stop and fast idle (if your idle speed isn't right straight off the mark). There are adjustments for the auto choke and secondary throttle stop but both of those need to be set prior to installation (the secondary throttle stop screw is impossible to adjust when the carb is bolted down and the auto choke needs to be partially disassembled to set the choke butterfly spring tension - both should've been set when it was assembled). The fuel bowl float level should've been set correctly from assembly too but you never know...

Check all the bolts and screws on the carb first. If they're loose it can cause air leaks into the carb body. Then look at the throttle cable adjustment to make sure it's not loading up the throttle. Hope this link helps you - http://www.mightyram50.net/vbulletin...ll=1#post43407

Idle is probably something I should have mentioned to begin with since I have noticed some issues with that. When you first start it up it idles pretty high, usually somewhere between 1500-2000. It eventually levels out once you start driving it, appears to generally idle somewhere around 700rpms where it in theory should be, but it's generally pretty damn rough, only smooths out if you give it a little gas and get it to about 1000rpms.

I'll have to check on everything else that was mentioned, I'll try and check it all out tomorrow if I get the time.
