I used slicks leakdown tester. Thank God for it because I would have parted out my blaster by now from a blown motor, it has saved me several time. Anyways, it detected an air leak through the clutch side seal. Thank goodness I still had my clutch cover off, I needed to wait until the engine was in the blaster and the cable hooked up so I could adjust it. So I took the clutch off and the gears to inspect the leak. The air is coming out right around that big spacer that goes right inside the seal, how do I fix that? I am guessing a new seal?
