Johnson problem

Hi folks, can anyone offer advice on this?<br /><br /> My Johnson "Stinger" 75hp, 3 cylinders,<br /> starts first time, runs fine, engages into<br /> forward and reverse fine, doesn't foul plugs.<br /> But this is all in my driveway with my water<br /> hose attached.<br /> In the river, once warmed, when I engage gear<br /> and slowly open her up, she dies. The only<br /> way I get going is by engaging her into<br /> "slow forward" then chugging around in a circle<br /> for about ten minutes gradually gaining more<br /> revs while attempting not to conk out.<br /><br /> I have had the carbs off for cleaning and<br /> they appeared fine.<br /><br /> I am presuming that the only difference <br /> between my drive way and the river is the<br /> slight increase in pressure hindering<br /> my propeller from turning freely but I am<br /> at a loss in figuring out what's wrong.<br /><br /> Any advice appreciated.<br /><br /> cheers, Craig ( U.K. )

Re: Johnson problem

Water pressure difference is alot more than you would think.<br />Have you check to make sure all plugs are firing?<br />Have you tried closing your choke a bit while this problem is happening? If so it could be your carbs high speed is clogged. <br />Did it ever run right?<br />Have you checked your timing? <br />Reviewing other posts using the search function would be very helpfull as this is a very common question.

Craig,<br /><br />It has been my experience that hesitation problems in 3 cyl. loopers is frequently carb. troubles.<br /><br />I would suggest you get a manual and perform the following.<br /><br />1. Rebuild carbs.<br />2. Perform Synch. & Link.<br />3. Check timing advance.

Craig, I am having similar problems with my 70 hp stinger 2. Starts idles great then go to put the hammer down and it chugs for 10-20 seconds then takes off. Have you been able to figure anything out? Mine runs great in the drive. I'm thinking possibly hs jets?
