I've started off with a 22x8 APC and she is still pretty rich on the top end.
I now have about 1 1/2 quarts through it and will put another quart in it before I adjust the high side.

If I just idle it it hardly gets warm to the touch.

It like a few drops of fuel to start when cold, but hand starts much easier than my G-62.
I'll have some numbers soon.

Ralph at rcignitions is selling ignitions for these for $75.00 with a lifetime guarenty, that includes crashes.
Gas-Glow is pretty cool stuff but I've never had an engine idle like this does.
You can count the rpm by the exhaust.

I purchased 2 more ignitions for my other twins and hope to sell off a couple of running engins to recoupe
some cash for other projects.

I just purchased a one of a kind Bellanca like the Miss Veedol in this months AMA mag.
It's the Miss Columbia. 2 weeks after the Linberg flight, Miss Columbia flew from New York to Berlin non-stop.
She has 150" wing spand.

The plane is about 80% complete, and I fell in love with her the 1st time I saw her.
I may have her ready for the Scale Masters coming up .... well just maybe.
