I put all new ignition,new head and all the gasket required purchased all part from marine engine rebuild carb good compression all new everything got water pump but haven't installed moved cylinoid to under cowling rewired off wiring diagram, had running for roughly 45 second rain great before I moved cylinoid then I rewired but now is now dumping fuel out the exhaust and will only fire over won't stay running i know everything is wired up right but just can figure it out I'm new to boating and trying to learn as much as I like can any help would be awesome

Perhaps replace diaphragm in the fuel pump.

Still have spark after changing the wiring?? Maybe it's flooded. Try with choke in "manual off" position

Welcome. I ran an exact motor up at camp for years and years. Bulletproof motors when in good hands. Solenoid wiring should not effect spark. Please remove both spark plugs and check to see that at cranking speed with spark gap tester you get a beautiful white/blue, "lightning like" spark to 3/8". If you don't have a spark gap tester, insert a number two Phillips screwdriver in each plug boot, one at a time, and hold it about 3/8 of an inch away from a head bolt so you can notice the spark jump from the screwdriver shank over to the head bolt. If it ran before you changed the solenoid position then you may have done something with the wiring or kill switch or "cutout switch", which is interrupting the spark......check out this thread from 2016 featuring our treasured tech, Joe Reeves.

PS: I'm not sure what happened to Kim but he was also a "helleva" tech. Guess the forum authorities dismissed him.
