28 hp johnny as in my signature, Around june I rebuilt the carb with a new carb kit, it ran decent, but had a hard time fine tuning the thing(it wanted to stall around 5 mph, if ya ran slower or faster it would run great),I took it to a shop, the tech opened it up adjusted the screw and said you should be really close. Since then I have logged maybe 8 hrs on it, and its getting worse, just 2 days ago, I was WOT till I got to the boat ramp, idled down and just as I tied it off, it stalled, no spitting no sputtering, just died, so I put it on the trailer and had a heck of a time starting it,(in the water still) Bulb was firm just wouldnt fire, Finally I put my fast idle arm all the way up before she finally caught and stayed running( I have never had to start with the fast idle arm more then 1/4 of the way up, plus the motor was warm already I shouldnt have had to use it). well just this morning I went to go hunting and it wouldnt stay running, it idled so low it would stall before I could get it in gear, After about 10 minutes and a switch of gas tanks it wasnt much better, but I got it to take off, it vibrated and stuttered for about 5 seconds or so and got on plain,So something isnt right.And now I have something rattling under the cover,I hear it at idle or WOT doesnt matter. What could the rattle be? sounds almost like keys rattling but its in or on the motor somewhere, and I wonder if this also caused my very low idle, like my timing changed or something? Unfortunatly at 5 am I couldnt see anything on the motor vibrating,I did notice alot of moisture under the hood, in the bottom of the housing, plus some milky looking residue. I may take it ot the ramp again, and fire it up went the sun is up <br /> Sorry this is so long, but I wanted to try and explain as best as I could.
