      Be sure it doesn’t have one cylinder dead – easy to check: take the spark plugs out and see if one is wet with gas from not firing. I wish I had a dollar for every time I assumed something was worse and overlooked the simple things to check first.

        I will revisit the ignition. Makes sense. It had spark when I initially tested it but my wife was the one looking at the spark tester. It might have been intermittent. She just said she saw spark.

          yeah, as Tubs said, we have all done stupid things, I could go on forever with my list. BUT, I remember my lessons, usually…..

            Spark looks really good. 3/8 of blue lightning.

              Hey Mark,
              You say the recoil and tank look awful now. This sounds like an early 50s Fleetwin with the built-in tank Nad the neutral clutch. Am I correct? If so, I have a ’53 that is doing the exact same thing. I went through the ignition and got that thing throwing a nearly 1/2" blue spark. I cleaned the carb on the motor since it didn’t seem too bad. I started it up and got it idling fair. When I give it throttle it won’t do anything past about halfway amd it smokes like crazy. My next move is to remove the carb and try soaking it, then blasting it out with aerosol carb cleaner and compressed air. I’ll cut new gaskets where they are needed and try it again. This has a Tillotson carb on it and im.much more famiar with the later 50s OMC carbs. I have worked on a couple of the Tillotsons now though. They seem to be a bit more critical of adjustments than whet I’m used to, but once you get used it, not too bad. I’ll be following you thread to see what other pointers you get though. I have to believe mine is a carb issue. The symptoms sound just about like yours.

              As far as ruining the paint, I’m sorry to hear that. Like everyone else has said though, we all have a list of stupid things we have done we wish we could undo that is much longer than we care to admit.

                Solution to analyze the spark yourself is to have her pull the recoil..yeah right. 😀

                  Yep Ben, sounds like the same motor. I have been through the carb on mine too, it also wasn’t bad. I put it in the barrel again tonight and started it up. It idles good in and out of gear but bogs down after half throttle. It is also getting hotter than I think it should. It felt hot so I measured it, 181 degrees. It seems to be pumping water well as it shoots across the barrel at idle. But, it does seem to lose some pressure as the motor speeds up. What sort of impeller does this motor use?

                  Is this carb sort of inverted? The small diameter fine thread needle is at the bottom of the carb and the larger diameter coarse threaded needle is at the top.

                    I did exactly that tonight. 😀 She said it just proved that she was right. 😆

                        The carb on mine has the low speed needle above the high speed needle like most other OMC motors. The Tillotson, however, has the low speed circuit set up with anew air screw instead of a fuel screw if I’m not mistaken. As the screw is opened it leans out the mixture instead of richening it. When it is closed it is not allowing any additional air into the low speed circuit so it is max rich in that condition. It’s getting late though, maybe I’m wrong.
