there are idle adjustment screws on the front on the carburetor run theengine and play with them until you have a smooth idle as well if theengine runs rich or lean you may have to replace the jets with largeror smaller ones, and perhaps check needle valves to ensure they openfully and have no varnish build up

AnswerUse a vacuum gauge watch as make adjustments at an idle peak vacuum will be a good base to start from
You may have to take the plastic caps off the adjusting screws then turn the screws slowly in ( clock wise ) until the engine start to run rough. If it does not change BY THE TIME IT IS SEATED DO NOT FORCE IT, BE GENTEL WITH IT. Then turn it counter clock wise until the engine smooths out. The engine should be running at it fastest. You can use a tack and watch the RPMs to adjust it if you don't have a good ear. Good luck Jerry
