a classic pnp for old two port engines with a
2 port cyl, carb, crank set:

the 2port pinasco 177 for old sprint 2port engines has HORRIBLE low timings and a tiny exhaust port. Urgent nees yo optimize it.

its in general NOT a race cylinder, its just a simple ccm extension of +52cc

u should optimize it, otherwise the performance is really bad... (compares to normal 177cc tuning)

pinasco kits do unfortunately mostly have lets call it "timings with potential" ;)
