    Tohatsu 50 TLDI 2003 <== Compressor oil

    Year is irrelevant; You did not mention model. Likely M50B2. You need to run DFI oil, not just TCW-3. Those motors do not inject oil into the fuel rail; I mists into the air stream after lubricating the bearings. What codes are stored in the ECU? Looks like some moisture in the air compressor.

    First Tohatsu motor 9.9HP

    Year is irrelevant; Model is everything. That model is covered in the combined 1 and 2 cylinder Tohatsu Factory service manual.

    First Tohatsu motor 9.9HP

    Yep. No carb kits anymore, but wp kits are available. Is there a problem with this old obsolete motor?

    8hp starts but runs only at high rpms

    That model does not have decompression.

    1998 Nissan 25hp

    You did not mention model. Year is irrelevant. If it's an old 2-stroke, such as an M25C3, just remove the intake gasket restrictor and reset timing. If it's a 4-stroke, you need a different ECU. Luis has a complete procedure elswhere on this board.

    Cutting out and stalling

    Decarboning always helps. Sounds like an ECU or exciter issue for the stalling.

    Cutting out and stalling

    What manual are you using? Trash the aftermarket manuals, and get a Factory service manual. Also read out any error codes stored in the ECU, then reset TPS initial setting and see if you get any more malfunctions or any codes. Carbon in the combustion chambers will raise the compression, not...

    No spark

    Using the manual as a guide, I would test the exciter and the CD.

    8hp starts but runs only at high rpms

    Which coils were changed, and why? Spark advance is built in to the CD, so that just doesn't get stuck at full advance. My money is still on the carb.

    90hp Nissian won't open up

    40D~90A: 6 pole setting

    90hp Nissian won't open up

    No, it won't affect running. How many poles did you set the tach for?

    Tohatsu m50d - Dragging piston with spark & Fuel

    That motor does not have a stator; It has an exciter and of course trigger coils. Full info is in the Factory service manual.

    8hp starts but runs only at high rpms

    The wheels have timing marks from the factory. Full info is in the Factory service manual. Make 100% sure you are right, or you could bend a valve. Again, I doubt you needed new rings. I trust you deglazed the bores and cut the ridge at the top, and adjusted the ring end gap correctly, else you...

    Cutting out and stalling

    Intermittent electrical will drive you nuts. If it only happens warm, you must test exactly when it fails.

    2018 Tahatsu 20hp efi Impeller

    The Tohatsu impellers last much longer than the aftermarket ones. Personally, I would wait for the oem unit to be in stock.

    90hp Nissian won't open up

    It shouldn't.

    90hp Nissian won't open up

    Still likely a fuel issue.

    Nissan wont start with button

    Year is irrelevant. Actual model is what we need. For that year, it could be either a 2 or 4 stroke. Are the battery cables reversed by accident? That will blow the fuse for sure.
