Looking for some help. My 1988 force 125 is running rough. At low and wot. Shakes and is not smooth. B Have only owned for a year, figuring things out but have run into a wall. It ran great one time out until I ran out of gas, faulty gage. Refueled and has run rough since. Replaced fuel pump membrane, rebuilt carbs, compression 120-125-125-125, Sinked carbs. Tried other tank to eliminate gas issue and ran the same. Always starts. Max RPM has only been 3600 but not sure if gage is correct. Prop is manual recommended. Bought an inline spark tester to check for spark and am showing no spark on all. Am I doing it wrong? It works on the lawn mower. Can the motor run without spark? Sorry for babbling. Help!!!
