My machine started acting like it was running out of gas. After seeing the gas was half full, I started pushing on things under the hood thinking something was loose. The wire from the spark plug to the coil seems to be the culprit. When I pushed on the coil end, it ran great. Should I get any resistance from that wire? It was pulling about 7 on the meter. I purchased a new wire, and it's pulling a little over 5. Is the problem my wire?
