Found another problem....arrrgh! I got a twister carb adapter from wacker engines and it doesn't seal the carb bore completely. There is a small crescent that is open to the atmosphere allowing air in from the back of the carb. No wonder it wouldn't idle. Not sure how to correct this, perhaps some silicone or marine epoxy? The twister bore must be slightly under 11.1 mm. I'll have to check, maybe I just need to align it better.
