Re: my "twin bee"
You have done a really nice job Chris, I do hope you get a video of it running.
Are you planning on doing any work to the tank/intake? I am sure the extra cylinder will require more fuel and air flow.

The normaly tank for the baby bee is a 5cc tank. With the twin is a 8cc tank .

True, just that the venturi hole and fuel inlet is sized for a single cylinder. It may work fine for two, just thought I would bring it up. It may be something you already thought of anyway.

Agreed on the nice job.
I was wondering about fueling as well

Re: my "twin bee"
Very nice Chris. How about a picture cutting the cylinder threads in the crankcase? Think that would be one of the trickiest parts of the project, both setup and the fine threadform.
Not too late to submit to "Engine of the Month".
What size prop?

Re: my "twin bee"
the prop is a 8x6 master airscrew, but it's so big, a 7x4 is better

Are the cylinders threaded into the crankcase?
