      The main difference in the newer gearbox’s is if you were to swap it directly with your old gearbox, the prop will turn in the opposite direction. The driveshaft and brass control rod may also be a different length. No problem as you already have the correct ones on your motor. The Lower unit control rod (3LGS37) is the part that is different on the two gearboxes. Your old gearbox has the right one for your motor. This is the part that will determine your prop rotation.

        I’m about to give up on this one. I can’t find gearcase parts for a reasonable price, so I figured I’d try to fire her up before investing more into it. Well, she runs for about 2 seconds and dies with the recommended carb needle settings. When I remove the plugs, they’re soaked in fuel. So I dry them off, lean out the needles and try again. Same thing – she fires and runs a few seconds, then dies. Check the plugs and they’re soaked. I’ve got both needles almost closed now and same results. Spark is good on both plugs. Compression is good – so much so that she’s a bear to pull over with the plugs in. I can’t figure what could be wrong. May part her out.

          Did you check the diaphragm in the fuel pump? Could have a hole in it. I do have some gears for this. The pinion looks like it had a problem at some time in the past.

            Forward and reverse gears.

              Well those gears look better than mine. I’ll get back to you if I decide to continue with the motor. I did check the fuel pump diaphragm and it doesn’t have any holes in it, but it is original and not real flexible. The good news is, there’s nothing attached to it, so a simple fix. Even if that was a problem, you’d think it would run longer than a few seconds on the fuel in the carb bowl? And why the gas-soaked plugs?

                I’d take the carb apart and look carefully for any way gas can bypass the high speed needle and get up the venturi. I’m thinking of the donut washer that mates with the center of the bowl at the bottom on OMC carbs that causes flooding – I haven’t had a Champion/Majestic carb (Tillotson if I remember right) apart for a long time and don’t remember if they have a similar gasket. Also be sure the spring-loaded choke is assembled correct and the spring holds it open instead of shut. Check float level also. There should be an easy fix to your problem.
