Last week I got a free 2475 Storm Troy Bilt blower for free with a popped engine, no biggie right? Never again. I was a big PIA to to do the swap conversion to a single shaft engine. The Predator bolted on fine but nothing lined up well and getting the speeds to work right sucked. I ended up taking off the shift shaft and grinding the lever and pin off to flip and re-weld them on then it worked ok. Next time I get one of those I will just part it out. Way too much time spent on something like this. Was very surprised it was a 2 shaft engine blower, but at least it works. Added the paddle mod as it only blew snow like 10ft but now will toss the stuff 30 ft. or so.
