It's a simple engine to run the OSGT15. Its ignition module is smaller and lighter than that of the GT33/GT60. I'm turning an apc 14x8 on mine. I'm using the same 50:1 mix as I use on all of my gassies, break in or regular running. Their instructions take you through an elaborate carb set-up which I did not use. My carb just needed about 1/8 turn leaner to both the HS and LS needles and that was it. I'm currently running the regular muffler on mine; very quiet since mine is rubber iso mounted. And it is as sweet a runner as the larger OS gas engines have been. I'm using a 240 ml bottle for the gas tank and it lasts about 20 minutes.

I plan to run a pipe on it at some point to get some reference data. The T-Clup doesn't need the power but I want to see what the mill can do.

Not much else to say about it. You have specific questions?

Wait a minute, when I re-read the post, you wanted info on the glow gassie. Can't help you there. Mine was supposed to be the glow version but Tower was taking its sweet time so I opted for the CDI version. No regrets....some comments on the glow plug have been negative but I take that with a big grain of salt since I don't know the experience levels out there playing with this technology.
