Now 1 of the things I have seen is someone bottoming out the lsn with out removing the hsn which damages the spraybar and or the lsn. Making it run rich in the 1/4 throttle range
IF you are an exp engine tuner an can't seem to tune it then yeah I'd change the carb.
I do love OS twin needle carbs try it an let us know
One of the first things i did was to get a new carb, but I couldn't see much difference. An OS carb would probably solve the problem, but I'm not sure I want to spend half the price of a new engine on a new carb... OTOH OS carbs are usually very good.
