So it fit just fine, clutch seemed identical in all ways. Nothing rubbing. But at full throttle it still not fully engaged. Maybe need to put my original clutch springs in? I read there may be some width issues with the clutch but they measured the same. Motor runs fine, cranked right up and seems to be hitting high rpms, can't lean it during break in but it does not sound rich at all. (I fly gas airplanes and know how to tune nitro and gas). Any ideas?
