Well if you remember a while back, I asked about rebuilding an echo BP blower. Well I finally got the parts, and got it running good. I had to replace both bearings and oil seals. About an hour or two to dissasemble, and about three hours to re assemble. So now I feel pretty confident about rebuilding small 2 cycles. Now a question for you all: What age did you rebuild your first 2 cycle engine? I am 17 so I guess you could say I am starting out early.
