I have a '96 Morbark 2070 with the 35hp 4 cylinder Wisconsin that just blew a piston. My mechanic suggested putting a new Vanguard 35hp 2 cylinder on as a faster and easier alternative to rebuilding the old V-4. At first I didn't think a 2 cylinder would be much good on a chipper, even a small one, but now that I look online I see that Carlton sells a 6" chipper with that same motor. I really need a bigger chipper but this little thing is so handy that I will want to keep it if I can, even if I get something bigger, and for now it's all that I have. So what should I expect in the way of durability out of the Vanguard? I know that it will have less torque, but I could deal with that if it worked at least decently and if I could get at least 1000 hours or so out of it.
