I have sv26cc engines with rear mounted walbro carburator. Both of them have flat type reed valve, which when opening are directing air mixture at the bottom of crankcase. What if I will install reed valve housing upside down, so the airfuel flow will be pointed directly to the cylinder ports?
Do I loose top end power because of that right now?
Right now the valve is mounted with bolts down. Im thinking to install it bolt up.
Here u can see the type of valve this engine has:
