OK, so I got a Revo today in the mail for a buddy and told him I would do his break in. I broke in mine just fine last fall. Today when I went to break his in, the ez start cant get the piston past top dead center.
When I take the plug out and run the ezstart, it turns the engine over but the engine has a very loud noise, almost like the piston is hitting the top of cylinder. I am sure this isnt the case but mine doesnt have nearly as loud of a noise when I am doing after run maintainence. I am assuming whatever is producing the loud noise is the culprit.
At first I thought it was the ezstart battery, but it is fully charged.
