RE: saito .56 gas conversion
what did you use for the ignition? in the ethanol post he said he used ch ignitions, looked them up but i guess they arent making them at the moment. i could butcher on an old system from a non workin motor somewhere, but i prefer a clean, classy lookin engine, so i'd rather buy a system that would make it look like it came from the factory that way.

RCEXL ignition systems seem to be the choice now that CH is (temporarily, I hope) not producing ignition systems. But, call them, they may have some CH systems left or some RCEXL systems for sale.

RE: saito .56 gas conversion
is it going to make any difference being a 4 stroke? what i mean by that is on a 2 stroke the ignition has to fire ever revolution of the crank, a 4 stroke only needs it every other so will it hurt anything having it spark on an exhaust stroke too? i wouldnt think so but it could make for some interesting backfires or starts since the exhaust valve will be open when it lights.

RE: saito .56 gas conversion
It doesn't make any difference that the ignition fires every time the piston comes up as on the overlap stroke, there is no compression and the exhaust is just finishing and the intake is just beginning. The combustion chamber environment does not have the proper air-fuel ratio for combustion at this point.
My ignition system came from CH but it is a RCEXL outfit.

I did a 150 and used the original carb
I used a Perry vibration powered gasoline pump and a Cline regulator on it.
You'll only need a 6 oz tank

RE: saito .56 gas conversion
The Perry vibratory pump is mounted on a plate from the factory. This plate bolts to the bottom two bolts on the back plate of the engine.
The Cline regulator just mounts right beside the needle valve with fuel line.
As an alternative, you can use a gas carburetor as a pump and regulator. There is a thread about doing this in this forum. You close the needle valves. plug the pulse hole, run a outside pulse line to the cover plate of the pump. Drill a fuel out hole in the side of the regulator area and run the fuel line to your glow carb. This is a lot cheaper than a $40 Perry and a $70 Cline.
