Update, I got the old kirby started I ended up just replacing the spark prong with a boot and terminal and bang it started. Bon scott thanks for the advice it was staring me right in the face I have a new problem now the mower ran fine for five minutes until I turned it off and went to start it again and the pull cord snapped Lucky it was right at the knot so I managed to fix it. I attached the pull start and now old kirby won't start could I of set something up wrong with the pull start? I had trouble with assembling these few parts spring retainer, dog starter and retainer. Maybe I set this up wrong? Could this be the reason why it isn't starting?
