[QUOTE="jdsgrog, post: 204735, member: 4307"] I'd advise to do the typical diagnostics: 1. Check for spark. Should be able to jump 1/4 inch with a nice hot blue spark on each cylinder. 2. If there is spark, check fuel delivery. Get a spray bottle with a mix of gas/oil and spray into carb. If it starts momentarily and stops, then you probably need to rebuild the carb. 3. Check compression. Should be near equal on each cylinder. if you need parts, I'd go to iboats.com, to their store. [/QUOTE]
