Looks like you have a CDI ignition. You need a resistor NGK plug. Way back in the day. They put cj8's and J19lm's in briggs powered push mowers. If you got close to a TV or Radio it would mess up the signal. Same as old cars>>>That hum you would hear through your radio. Non Resistor plug. And don't go cheap on the battery's. If you really want to sell it or >maybe trade???? Let me know. I grew up in WA. St. watching Miss Bud Kick butt in the races.
ah... yeah me saying i was going to sell the bud boat was pretty much a joke ,at the time i was frustrated ,and decided to post that.the boat is working nice now.. but i will show my buddy those boats you have...
