  1. Piston ring problem

    Technical Help Forum
    My resto project 82GL was fairly easy to get running. Rebuilt/cleaned the carbs, threw in a new battery, air filter and spark plugs and away she goes. Although I don't have the tools to check I had a sneaking suspicion it may not have been getting good pressure and possibly leakdown problems...

    Hello, I just changed the left side top gasket. After assembly, I adjusted the valves. TL on top of compression. Then decided to check right side valve settings. Intake needed adjustment, no problem. But exhaust valves had no clearance at all to rocker arm seat - so no possible way to adjust...
