Carb Help needed please!

I don't know how thorough you where in rebuilding the carburetor, but all brass plugs should be removed and the passageway cleaned, especially under the GAV needle. In most vendor carburetor kits, the jets are not the correct size. Before using they should be flow tested. Fuel float should be checked for leaks and set to the correct height.

I have not removed the brass plugs which in this case, maybe I should do being I purchased the upper and lower bodies and do not know what shape they are in. I did check and set the float valve for adjustment and float for leaks. But looks like I need to get into it more!

I wouldn't drill out and replace plugs. You run the risk of cracking the casting when forcing in new plugs. Not necessary. Glass bead the passages and run paper clips through the passages to check

I would agree with RonC. Don't fool with the brass plugs. There is a good chance that you will screw up and destroy the carb halfs. Do a complete disassembly and use a common paper clip. you will have to bend the clip in different shapes to get through the 5 passage ways. Use a needle nose pliers to help to push the clip through.(Be patient) then use compressed air to blow them out. Then have the two half's bead blasted and make sure to get into each 4 passage ways. Then redo the the compressed air to the passage ways. Have the 4 jets flow tested. Here are good flow test # Main Jet 158 ML, Cap Jet I73 ML, Comp Jet 143 ML, Idle jet 54 ML. Place a gasket under all except the idle jet. Turn the throttle screw 1 1/2 turns open and the air adjustment also the same and AVR nob (Choke rod) 1/4 turn counterclockwise. two main things to remember clean passage ways and jet flow rates This should get you up and running.

Good discussion on paper clip method discussed before:
