Pullstart backplate
I got this for an lrp 28 and It had a pullstart, but I didn't want to replace all the pullstart stuff and I didn't want to file down the nub on the crankshaft incase later I wanted to get the pullstart styff. Anyway it fit perfect. I don't know what the other reviewer used it on but this item works on any sh manufactured. 28 nitro engine
