So bad gas was the culprit for my hard starts. A little seafoam in gas and starts great. But....the stalling out....if i turn idle down is due to clutch drag! I had it in gear....clutch pulled....and it started moving forward on a slight uphill. Thats when it started idling down and stalled out. Tried again. If i revved...stopped dragging. I adjusted clutch. But it seemsni cant find a in between. Its either dragging or slipping under hard power. I think i recall someone saying use only oem clutch plates somewhere. Just not sure if that applies to 450s. Im thinkin plates. Any advice on what kind i should buy?
