    Not shifting to reverse / 1978 Mercury 500 Thunderbolt 50HP

    Hello just recently I had issues with the motor to shift to reverse gear, no issues to forward only to reverse. It seems it wants to shift but makes some grinding and dont engage fully. Is there a set up procedure for the shifting cables any one can share? Thanks

    Milky fuel in carb intake force 85hp

    Thanks gica, it looks different to me eyes yours and mine, I'm gonna take a shot and take it to the lake again, hopefully it was only the pump. Crossing my fingers.

    So I finally got the pump diaphragm, valves and some gaskets I thouvht were bad and rebuilt the pump, it fired up very quickly sounds good on muffs 1200 RPMs no issues would not Rev up more on muffs. I didnt get the boroscope so I rather took off the head again to have a look after warming up...

    Gas electric generator issues

    Thanks will clean the carbs and get it running, this generator also has a fuel valve from the deposit to the carbs, so next time I use it instead of just shutting it off when I finish using it I will close that valve to get the carbs starve.

    Gas electric generator issues

    Hi I have an small gas powered electric generator, it is a 2 cycle motor, I hadn't used it in a couple of years, I couldn't get it to start up so I inspected and see that it had old gas there, fuel was not flowing, the float needle was stuck up so it didn't started. I Cleaned the carb got new...

    Milky fuel in carb intake force 85hp

    Thanks I will order an endoscope to take a look, having the haead leaking the first time I started up also makes me wonder, although right now I'm leaning more to the fuel pump issues but I guess is good to look every aspect of this "rebuild".

    Milky fuel in carb intake force 85hp

    Hi, racerone I usually put the throttle lever to Max accelerate out of gear, push the choke and keep it pushed while cranking. Battery and starter are in good condition, I see and hear them spinning at good speed, I was just mentioning that I see a difference in the cold starts in this different...

    Milky fuel in carb intake force 85hp

    Agree I don't think the Jets are what is causing me the current issue, just wondering why it have more issues starting it at the lake than at home. I don't know what jets it has but I guess they are 0.074 as there are no lakes near my location and this boat has always been used at lower altitudes.

    Milky fuel in carb intake force 85hp

    Thanks, maybe I didnt explained myself very well, I can pull the throttle lever to accelerate without engaging the gears, this is I guess a function for cold starts, in that way I can accelerate up to 1600 RPM's that is the maximum it allows me to do with this function, everything looks good...

    Milky fuel in carb intake force 85hp

    Hi gica, I didn't open exhaust or intake covers didn't wanted to mess with it, in muff or tank I can get 1600 RPMs in neutral not in gear just idle acceleration, I didnt try with gear on because my tank is to small and all water be gone and muffs I believe is no good to do it. I missed some...

    Milky fuel in carb intake force 85hp

    Went out today again to the lake, same result ad before, it will not pass 1200 rpms and then it dies, I can run it lower RPMs for a while with out dying, I noticed that if I click the choke when it wants to die it gives it s little life so I'm focusing in the fuel pump now. I must admit I used...

    Milky fuel in carb intake force 85hp

    Didn't noticed any, actually the service I did to the pump previously was changing the check-valves so I got to them.

    Milky fuel in carb intake force 85hp

    That picture was before the rebuild, yesterday night I put it back together in the same orientation but with the nut in the outside. I adjusted again to 28° at cranking speed. I have read that the idle timing should not be affected and would not be needed to be adjusted, anyways what should be...

    I saw some pictures in the internet from what seems same motor 1989 85HP Force, and this assembly looks to be installed backwards, the adjustment screw falls under the flywhee, (I had it like that before the rebuild but thought it was worng because some other pictures I have seen in the internet...

    Milky fuel in carb intake force 85hp

    Thanks I will check that, previous to the rebuild I checked on spark and it was 3/8" strong, I'll recheck. Fuel pump is new and I serviced the pump as well, I don't think that is the issue, I'll take another look. I think I have a Syncronization & Timing issue. My doubts are on the timing, will...

    Finally got it to the lake, not the best output, motor started no issues idled good, but it didn't reved up. No more than 1200 RPMs, I dont know what to check now, some how I think its a timing issue, I redo Frank's procedure, see if something is off.
