Here is the completed Monster SnowBlower, I painted the engine Cowling, Tank, Engine Block, Muffler Cover to give it that nice fresh Look. As you can see everything looks nice and stock when buying parts the only thing that is not stock are the 2 belts and they are off the self items. The real challenge was mounting the idler pulley on the drive belt I managed to finish this with scrounged parts I had lying around the garage. One other item I have to change is the 3” drive pulley I made the mistake thinking the 5/8” would work better vs the ½” The only item I have to get is the pilot Jet the original is missing and they are back-ordered from Honda till the end of Jan 2011 If anyone out there has a carb from a GX120 to GX390 or a clone Honda I will buy the pilot jet. All I need is snow here in Toronto it was 50-F the other day. Winter generally starts around Jan 15 in these parts of Canada Now for the Next Project. It will have to be a Bigger Engine and a Bigger SnowBlower. I have my eye on a mint 32-Inch John Deer “How abought a Twin 20-hp engine”

Mn-Runner you were correct the auger pulley was out of allignment by 1/4" and I also re-installed the same size ideler pully as the orginal. I installed a larger idler-pulley thinking it will be a heavier duty unit and for some reason that made the belt shake like crazy in the stop mode. I wish I did have the gun that would have help. One other point eventhough it has the ajustable idler pulley. I am using a 1/2" x 38" belt It is just loose enough to work with the 3" x 5/8' auger pulley. I changed the pulley to 1/2" x 3" so I would be consistent with the lower auger pully now the 38" belt is to tight and the 39" belt is too loose even with the ideler pulley adjust to max-in. I re-installed the 5/8 pulley with the 38" belt. Buttom line if I want to use the 1/2" pulley I will have to find a 38-1/2" belt. All off the off the shelf belts are sold in 1" increments. At this point I am hopping the 5/8" pulley will provide a good grip using the 1/2" belt. Nothing is straight forward. One step at a time I guess.

I seem to disagree. A "v" belt is supposed to ride on the sides of the belt and at the bottom of the "v" is supposed to be a gap, so when the belt starts to wear and get thin it can still have friction to drive the pulley where as if its riding on the bottom of the V it will start to slip and haet up. By using the 5/8" pulley the belt is sinking lower to the bottom and when that belt starts to strech a bit you will be losing grip and heating up.
In a previous post you talk about A and B pulley combo pulley. A 1/2' belt is the same as a B belt but a combo pulley will have the wider belt ride on the outer edge and the narrower one lower to the center therefore when you use the combo pulley your belt ends up to long because,the diameter is smaller using less of the belt. You must look for a half inch increment belt or utilize the idler pulley. I can't see why you dont use the 39'' belt and utilize the larger idler pulley to take up the slack.
