Adrian, do you have any dimensions on the 36? I would guess that it's a bored out 28/32, but one never knows. I haven't been able to find a 36 at a decent price. The 32 as I have it now is about 13cm (5-1/8" ) from the shaft CL to the top of the cylinder.
I plan to do a couple of these 32s with EI so we will see what they weigh. As I build mostly WWI AC I don't really care so much about weight as you don't find too many nose-heavy WWI AC

. I do like the easy starting/hand flipping with the EI, though. These 32s are much more compact than the Honda. I have a GX35 and it is bigger than my Stihl 65cc!
