Well just got my carbs sorted. Went for a drive and something has come unglued in the bottom of the engine. Huge loud slapping like a rod banging. Very rpm related. On the 3 4 side. No damage to the plugs. Still runs but it is clear that something is very broken. Will check valves tomorrow but I am betting the case has to be split.
Any thoughts on easy things to check or where to start? (IMG:style_emoticons/default/headbang.gif) |
