I just put a Ralph G26 in a 1/4 scale world models cub. Ralph shortened the hub so it would fit in the cowl. Motor fits perfect, had to cut out a hole for the carb and the bottom for the sparkplug and muffler and for cooling. Motor runs great, just having some problems adjusting the high needle. Needle is close to the prop. I need some suggestions on how to set the needles. I have it close, but not sure.

Thanks
Ellis
