The battery is fine. I tested it and was still at 6.1 volts. I think I solved the problem but I have to wait for a replacement part to arrive to be 100%. the reed block is missing the flapper. I took the cylinder off the engine and found parts of the flapper in the engine. Obviously it broke off and was sucked in. I cleaned out the engine and put it all back together. Just ordered a new reed block.
