Does the Tomos A3 have a reed valve?
What is the correct way to install it on the bike? I was helping a local guy work on an '94 Tomos with what I believe is a reed valve. We cleaned the carb, and replaced a gasket between in the Valve and the intake manifold. It would fire once or twice out of 30 kicks. The spark is good and strong. It has good compression. What are the signs of a bad or defective reed valve?
