Hey guys, it's been awhile since I habve been on this forum. So long I forgot my old login. Anyway, I have a stripped down lightened up 21 CC Weedeater motor that I want to run on glow or gas/glow and was wondering what nitro carb might work. I thought maybe the Super Tigre .90 carb but wasn't sure. Motor ran good on gas and spun a 15X6 to about 7400 but proved to be too heavy for the SPAD it was in. Now that she has dropped more than a pound I wanted to lose the heavy walbro carb and go strictyly with a simple two needle nitro carb. Adaptor would be in the works as soon as I decide on a carb. Thanks guys for any insight.
