The stock carburetor has earned my desire to replace it. The engine seems to run out of air at about max torque, it certainly does not like to rev and it coughed at exactly the correct point to get me killed. One of the first choices to come to mind is the Carter side draft with the moniker of "YH". My initial efforts have determined the most common size is 1 11/16" bbl. The Alpine intake manifold throat is 1 1/2", opening up to something more like 1 5/8". Would this mismatch be a problem? I can probably bore it out if necessary. Any info on the flow capability of the 150? I have seen two ratings on the YH, 195 and 128. Which is correct? Is either correct?
Any ideas on a better carb?
