RE: Source for cylinders?
BME - Keith Baker of BME was nice enough to sell me and a friend parts to build a pair of 61cc twins. Got the Echo crankcases, pistons/cylinders and prop adaptor from him. Had to get the crank from a dead chainsaw. we had to wait quite a while and it took a few phone calls to make it happen, and this was well over a year ago before they got really busy! I really appreciated this as he did give us a sweet deal, but he likely wouldn't do this again. My understanding from what I've read right here is they're very busy trying to keep up with things - you never know though, doesn't hurt to ask and see if he'll do it again... Here's a pix of the 61cc twin I assembled from parts. Just waiting for mufflers, due in soon.
