I have seen this type of pulley arrangement in snowmobiles, and am kicking myself for that not occuring to me before!! You are exactly right, ..I was up at the shop just last night looking for more grease zerks and other lubrication points that I may have over looked. I started it up again and without moving, I actuated the "high-low" drive. The belt has about a 1/2" "flop" on the top during the transition, and never rides out on the top edge of the engine pulley. The thought of tightening the belt out of experimentation had then crossed my mind. Top ground speed now is comparable to a normal walking pace, and I know this isn't right. If the engine pulley had more squeeze, the belt would ride out further on that pulley increasing the speed. Low speed is there, but slips on slight loads. After shutting down last night, I tried rotating the pulleys by hand to look for any other lube locations and about burned the hide off my hands. An obvious indication of a lot of friction or slippage. Your diagnosis is right on! I'm planning on splitting that bottom pulley apart and having another look. Thanks for the reply!!</p></blockquote><p></p>
