Well it started last year I discovered that my 2005 MS290 was melted, I used it to heat my home for 5 years or so and it has seen sporadic use since then. I rebuilt it with a HIPA P&C from Amazon, original OEM crank and Koyo 6203 c3 bearings from Ebay. Has a blast doing it, was super easy and runs great! Had been thinking about one of the Huztl kits for a while so got the 440 and with the help from here and M.O. step by steps videos got it together and running well! Mostly all from the kit except for a different chinese carb from amazon, oem control lever and an Oregon clutch drum. Well now what? I needed a small saw so got the Huztl MS180 , super easy to build, everything from the kit except the clutch(springs were too heavy) and throttle rod(too long). Both start easy and run well, only have about 2 tanks through each so far so time tell. I think I'm ready to do the 660, getting bored!
