Hmmmm, this is of interest to me as well! Ive got one 372xp that I put a AM BB top end on and an AM muffler that is basically a hollow can. It runs decent but its a fuel hog! Most of the time I can cut a load on one tank of fuel but not with this one! Id say its 25% less fuel efficient than my other stumping saws and they range from stock 372s, 576s and 390s. Ive got another frankensaw in the works right now that Im looking forward to playing with. Its a combo of 371, 372, china case half, OEM 76cc P&C, AM open can muffler, and stock walbro carb. I wanted to try a 390 carb on it but I don't have a spare intake boot handy. All it lacks being ready to cut is the top plastic. Its a compression FREAK right now! I don't have a compression gauge but its got more than any other saw Ive got, including my 390s and a 660 stihl!Westboast or any of you other guys running modified 372s have you played with any different types of mods for logging application? I have two OE 372s, one done by Walker’s and the XPG was stock until Friday night. I muffler modded it with two 1/2” front ports and then just cleaned up the exhaust port and deleted the base gasket which put me still pretty conservative at 0.024” squish. Anyway, why I put this here in forestry instead of in another saw thread is because of the fuel economy. It doesn’t feel much less powerwise than the Walker’s saw, maybe a touch slower but might be a bit torquier even. But, it’s a marathon runner! I limbed and topped probably 50 trees, cut slash for our cat for skidder trails for an hour and fell four decent sized trees on 2.5 tanks of fuel today. Run time was well over an hour per tank. I’d say it’s 2x as long on a tank as the other saw. I did this with a 359 previously with very similar results too. Thinking this might be the way to go for me. I’m making up with a touch less power probably five to ten minutes an hour in service time. I won’t be able to see how many trees I can dump on a tank with it until we get skidded out in a couple weeks but I’m impressed so far. Thoughts?
Yes... I modified my intake on the early shift (fire hours) 1 O'Clock became 'beers O' Clock'......Westboast or any of you other guys running modified 372s have you played with any different types of mods for logging application?
Is your main saw a 660?Less then a year on a saw!
Either i don't cut enough or i need to Run em harder 5 years and counting on my main saw, far as i know the one it replaced is still cuttin wood as well
461 bought 2 of em when they first came out, only issues other then me running them over have been detonating spark plugs, bunged up carb diaphragm, and several pull cordsIs your main saw a 660?
