Hello GSF. I've just installed a M232 on my PX. I have match ported the cylinder to the cases and am running standard ignition (have kytronic unit too) currently set to 24deg and curve 7, SI24/24 carb with drilled out float chamber passage 2mm, SIP #4 slide and DRT #7 float chamber top lid, 160/BE3/132, 55/160, SIP XL. My issues are that it is a little stuttery at light throttle and it hasn't the power that I would have thought it should have. Can anyone tell me what I should be looking for or see anything obviously wrong with my set up? My thought would be timing but not sure...thanks in advance.
