Hi guys I have an old pontoon boat that I have been playing with for about a year or so. I just spent 800.00 getting the carbs rebuilt and a lower unit replaced, tune up etc. The motor ran great at the shop and has good compression. This motor has been pieced together with 115 and 135 parts. I went to rewire the ignition switch and blew a fuse over the solonoid a few times but got it right after getting the right diagram, but now the engine is sputtering will hardly idle and i have to choke to keep it running but even doing this makes the engine race. I am a first time boat owner so dont laugh but I did use 50:1 oil with a gallon of gas just to get the switch wired and I added justa lil oil to keep from frying anything. I pulled plugs which were replaced a couple of weeks ago they were quite black and oily. Would the plugs make it that sick?? this thing is really missing bad I am going to change them out and try again. I am wondering if I might have burnt something up like the powerpack or rectifier when I kept popping those fuses. I do have the manual but this is a frankenstein motor it has parts from the 70's, 80'S and 90's. So have a laugh and shoot me a reply if you have any positive comments...
