I picked up a older Owatonna Mustang 1700 (mid 70's) with Variable Drive and the 104 CID Ford V4 this is not the torque converter model. My question is when turning over this unit with the starter or by hand the drive shaft to the pump turns and drive and driven clutches both turn which the inner axle shafts turn but the wheels are stationary. I'am in the process of getting the engine ready to start (been sitting for 10 yrs). This appears to me to be a large load on the starter and motor to try to fire with this much of a load with everything turning. Correct me if I'am wrong or is this just common with the variable drive system - Thanks!
