So the 15cc and 20cc engines do not run on crankcase pressure like stated on the website, but they run on muffler pressure?
Do you guys have any idea how much pressure the regulator system in the carb can take? Would it be possible to use a checkvalve and crankcase pressure? Or is that just too much for the regulator system?
we actually didn't test these with crankcase pressure and a check valve because of the extra complexity that goes with it. It should work ok but I have no advice as to where to start with the needle valves because the pressure will no doubt be much higher and I suspect you'll run into problems transitioning between high and low throttle. Because each check valve on the market actually locks in different pressures each setup will be different from one user to the next.

ps-which website shows these as crankcase pressure engines?
