Yeah I bought the lrp backplate as I was going to convert it to a rotostart because the pinch was so tight for the break-in and I was breaking my pullstart. but the engine is still a pullstart and the back plate is still in its package. I guess I will have to see what I will need to do to make it fit with the pullstart and if its too tight to fit with the pullstart I'll do the conversion to rotostart
