Got the Kioritz running on gas/glow (23.6cc), man is it fun to let it go full throttle for an entire tank. Doesn't require constant glow power, either. Dad went wayyy back from it (20-30') and watched as the wind blew his unbuttoned shirt back some.

Anywho, I was wondering just how you know when the carb is too small? I got it to run but it wouldn't prime itself, even when I would block the carb venturi intake (may be a leak, previous owner put some sort of 1-2" tube from the venturi, I'm assuming to get it to stick out of a cowl or something). If I put some straight glow into the cylinder (requiring removal of the glow adapter) and started it it would run for a bit and either 1: get fuel from the tank and keep running or, 2: slowly die and require more priming.

After I got it running, and to my ears it sounds like it's running very well, I noticed that I had to have the high mixture almost fully leaned (as much as I could turn the screw tight with my fingers). Does this mean I need a larger carb? Also, the high mixture screw is the one closest to the cylinder, correct? Would a larger carb fix the problem it has priming itself? I'm not running exhaust pressure so I'm not sure how I can prime it like I'm used to (blocking muffler, turn over a few times).

For fuel I have Tower 15% nitro 18% oil that I'm mixing with HEET (stuff to remove water from fuel lines) at a 1:1.8 ratio, then I mix that in a 1:2 ratio with straight gasoline.

I'll get a tach reading tomorrow.
