My Dad bought 2 Super 1050's new back in the 70's, and I've had 4 all told, I'm back down to two now. Back when he had the brand new one's, I found that if you put the trigger lock on, and it held the throttle open some, they cranked over pretty easy. Easy at least for a 100CC saw with no decomp. I also found that if I was running a 36" bar on one of them, I would just set the tip of the bar on a log, hold the trigger with my right hand, and crank with my left, and they would start easy. If I left the throttle closed, I could hardly pull the rope out, and it would pop back and rip my fingers off. I asked the question here, why they seemed to crank over much easier with the throttle open a little. Someone answered, "Reed Valves". But that was all they said? I know my Mac 550 at 99CC's does the exact same thing. No throttle and it will pop back and rip your fingers off, crack the throttle open a little, and it cranks easy
