I have a 95 Bayfisher with a Yamaha 115 that only gets run once or twice a month. Starting her cold is always an issue. I follow what I believe is the normal routine of pumping bulb until firm and using choke switch. Motor does not want to catch. Eventually, it will start but it takes 10-15 minutes. Plugs seem to be ok. If anybody has the magic formula, I am all ears.
