    2003 Tohatsu 18 4 Stroke Oil Light Cold Starts

    Hello everyone. I have a 2003 Tohatsu 18 4 stroke short shaft electric start. I've done a good amount of work to get it running nicely since I first got it in 2024. But this is the first 4 stroke outboard I've really worked on. And since the day I got it, it would sometimes start cold with the...

    Early Honda B100 10 Horse Rough running

    I appreciate that. When I get the chance, the head will be coming off. I do have a newer b75 with the cdi ignition that seized and I might be able to make parts of. It will be a good learning experience as I only ever went into two strokes this extensively.

    Early Honda B100 10 Horse Rough running

    I added new gaskets to the intake and exhaust housing. I adjusted the valves to 0.004in. It is doing the same thing. It runs the same. One thing I forgot to mention is that the carb that came with the engine was broken but I sourced one from a 7.5 parts motor. Are these carbs too different...

    Early Honda B100 10 Horse Rough running

    I’m not too keen on removing the head and sourcing a new gasket but I will keep that idea in mind. Can you go over what you mean bulky “Overhelaming”? If you mean overheating than no, I believe it is staying in operating temperature. It is peeing a strong stream. I did end up replacing the...

    Early Honda B100 10 Horse Rough running

    Okay. I believe the timing is right since I had it idling. I went into the valves today and adjusted to 0.003 inches with the feeler gauge. They seemed too tight before I started. When I fired it up, it seemed I had solved the problem. When I took it to the water, I worked the throttle up and...

    Early Honda B100 10 Horse Rough running

    Thanks for the info! It seems like a sweet old engine and really wants to go. When I was able to get past the rough hesitation, it topped out around 17 mph on my 14 ft gregor boat! About 1 mph slower than my 15 horse Chrysler, with slightly less power down low but close. I always wanted one of...

    Early Honda B100 10 Horse Rough running

    Hi everyone. I have what appears to be a late 70's early model honda 10 hp with the points ignition as opposed to the cdi ignition. It is only wanting to idle but inconsistently able to reach max rpm if I ease into the throttle. If I try to throttle it too quickly from idle, it will bog and...
