just ran them tonight with poor traction and low snow,cant get rpms out of thempull to 8800 then fallsto under 8000 then starts back up, never had a lond pull though,guy i bought the cpr kit says jeff set it up the way he got them and thats the way i got them, there is 2 thick washer under the bolt on the heel and a allen screw in the sholder sticks out quite aways just so it clears the sliding shieve in the primary is this right?>
