Convert engines with crankcase supercharge?
 

Has anyone successfully converted any engines with crankcase supercharging?
YS? Shindaiwa? Whatever?

The Shindawa is already a gas fueled engine and cgangine to a battery powered CDi would make it lighter. I think RC Ignition has done one or two.
The YS is a non-starter as the fuel system has silicone parts. Silicone and gas do not get along very well.

Yes, I am aware of the YS silicone issue.....think you were the one who reminded me the last time.

However, I am not familiar with a YS. Can we bypass/dismantle the silicone parts?
The silicone parts are mainly for the fuel pumping action right?
So a walbro carb may be able to provide just that?

Just some guesses ...........

The silicone diaphragm is the regulator, not the pump. This regulator is more complicated in operation than what the Walbro is.

The Y-S regulator combines engine speed, tank pressure, and engine suction into a proper amount of fuel.

Enjoy,

Just a thought...how about using a cline regulator....on the YS engine? Capt,n

Hello Captinjohn

Did you manage to convert the Shindaiwai engine for RC?
Also, does that Shindaiwai have Crankcase supercharge?
Thanks!

I did not convert a Shindawa. I think it may have a super charge effect. Not sure. Capt,n

Is there any news on the Shindawa 4 cycle engine by now. Last post was over 2 months ago!!! Capt,n
