    Yama carburetor 15 vs Tohastu EFI 15

    carbs are open to the air and let the fuel evaporate leaving residue behind, Fuel injection is a sealed-up system so the fuel does not evaporate from the rail, and I am fairly sure even the VSTs should not allow fuel to disappear due to evaporation while just sitting.

    buying an old motor that you cannot run with load to make sure it will run properly and not overheat or something else is always a gamble. if you are handy and you get it at a good price you can spend time and money to get it running well most of the time

    very old motors are all a gamble, use the motors info to look up parts to see if you can still find them

    No ckoke on T50TLRC

    Prime start should be automatic adding extra fuel when cold, pushing the key in does nothing. but I am not familiar with your motor. might need to get a service manual for it. it will have specs and all sorts of procedures. need to make sure all passages are clear for that extra fuel to be...

    did you check for spark? take it to a real marine tech. I hope you took the carbs completely apart before soaking them

    2003 ox66 200 intermittent shut down

    ( if these are plug together connectors) I would unplug it and inspect the connectors to see if corrosion is a problem, clean , and lube them up. disconnecting and plugging back together may help clean them also

    2003 ox66 200 intermittent shut down

    if you truly believe the VST is not running out of fuel and the pump in the VST is not running when it dies, then monitor the + to the pump to make sure it stays on. the ECU should toggle the neg to make the pump run, it will not run if the + is not there

    2003 ox66 200 intermittent shut down

    might check to see if 32psi is the correct spec on what pressure you are reading. ( Rail or even the lift pump pressure) If you still have spark on the plugs, then you need to find out if the VST is running out of fuel or if injecter pump is shutting down when it dies. quick way to tell would...

    2019 25hp Yamaha Fouls lower plug but not the other ?????

    still need to see if one or both are getting spark when it runs bad. Have to eliminate what you can from being the problem, to search for only what truly is the problem. as I said an inductive timing light will show if spark is happening and if it is steady and it can show you if the timing of...
