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
