Yes I do, 200 rear handle, 201cm rear handle and the earlier 201c rear handle with a timing advance/mm/limiter removed. The 200 is a factory hotrod and being a hotrod had plenty of problems primarily related to the carbs. When you get them right they scream, I just brought mine up from the basement so I checked the tune, 14.7 no load and sounds good there
. The 201's run well and get better fuel economy, but the 200 beats them in overall cutting efficiency(more torque if that's a thing in a baby saw lol) so you loose what you gain in actual fuel economy if they have the exact same tank size(I'm unsure of that).
I prefer the 200, but I run the 201's more on jobs because I want to keep the 200 in great shape for as long as possible. Although if I needed a small rear handle saw for doing a job with a bunch of invasives I wouldn't shrug off a 201. I would however look at some of the offerings from echo and consider a ported 2511 in the rear handled version even if I had to have one shipped here as I don't think they've made it to the states.
One funny thing I've noticed running the 201cm is I look down to see if it's the standard carb saw because it seems to run a bit fatter than I'd like it to
.
I'll see if I can't do a video today of the 200 and the 201cm running together in the same wood since I've had a few guys ask about them.
