I purchased this engine in the marketplace.appears to be in good shape,has the parts to go back to glow.this has a mechanical advance tied to the carb.The piston skirts is black from either carbon or varnish.I now this is normal for glow what about gas?
I believe the conrod is bushed so what oil and oil mix should be used?
What would be a good starting prop.was thinking of using this in a esm dauntless.

4.8V battery for ignition, 12oz of good oil per gallon of gas, 18x10 prop sport flying adjust pitch and dia to suit your flying style.

thanks,think you mean 18-8 prop.at 12 oz per gallon what ratio is that?and what would be a good oil?there are alot to choose from these days compared to a few years ago.

With 128 oz/gal wouldn't 12 oz of oil per gallon work out to approximately 10:1 gas to oil?

Lets post after coffee, 18x10, 10% oil, Pennzoil. High 7k or low 8k rpm.

test It with 10X10 prop

I tests it gas converted I get same rpm with 206-10 with 15% nitro than gas
6700 rpm
Was my firt engine conversion


Now I have finished a new one
This one has no the backplate prezurizatons for pum. Now I modified Walbro. Will take video tomorrow
