chris.brock Posted April 21, 2017 Report Share Posted April 21, 2017 If you've been pulling the cord for a while, the plugs should be blatantly wet. Link to comment Share on other sites More sharing options...
Rizzo Posted April 21, 2017 Author Report Share Posted April 21, 2017 pulled til I couldnt pull no more, definitely not blatantly wet. I called the seller...he talked about some carburetor float being possibly stuck...this is getting beyond my technical expertise I think Link to comment Share on other sites More sharing options...
Rizzo Posted April 21, 2017 Author Report Share Posted April 21, 2017 he did mention stomping on the priming bulb might free it up? Blast of pressure...assuming this is even the problem Link to comment Share on other sites More sharing options...
chris.brock Posted April 21, 2017 Report Share Posted April 21, 2017 I was thinking a crudded up carb from the beginning. Where do you live? Maybe someone on here can help you out. Link to comment Share on other sites More sharing options...
Sinker Posted April 21, 2017 Report Share Posted April 21, 2017 If you are lucky the seafoam you added will make it to the carb. Id change the plugs and try again tomorrow. I have seen seafoam foul plugs on a really dirty engine a few timea. What kind of kill switch is on this engine? S. Link to comment Share on other sites More sharing options...
chris.brock Posted April 21, 2017 Report Share Posted April 21, 2017 If the float is sticking it would probably be a good idea to clean the whole carb. Link to comment Share on other sites More sharing options...
Old Ironmaker Posted April 21, 2017 Report Share Posted April 21, 2017 Spend the 100 bucks and take it in to a Marine mechanic. Sometimes you just have to "call the guy". Have you done a compression test? It takes all of 10 minutes. Link to comment Share on other sites More sharing options...

If it was 100 bucks I would definitely call the guy. The problem is there's plenty of guys trying to make a weeks salary from one carb rebuild/ cleaning.

Chuck Enwinde Posted April 21, 2017 Report Share Posted April 21, 2017 If you're anywhere near Georgetown there is a guy named Randy that works out of his garage. He rebuilt the carb on my Nissan outboard for a very reasonable price. You can find his contact info on kijiji. Link to comment Share on other sites More sharing options...
DanD Posted April 21, 2017 Report Share Posted April 21, 2017 (edited) There's usually some form of drain plug or screw on the float bowl of the carb. By removing the plug or loosening this screw, will tell you whether there's fuel getting into the carb. With the info I had, I googled 8 hp Nissan and got this pic. If this looks like your carb the drain screw is the one circled? Once loosened or removed you should see fuel dribbling from the bowl; if not try pumping the fuel prime bulb. If the bulb becomes hard and there's still no fuel dribbling; try tapping the carb's fuel bowl with a screwdriver handle. Don't beat the crap out of it; but a number of solid smacks. If the float or the needle is stuck; the pressure from the prime bulb and you hitting the bowl may knock it loose and allow the fuel to enter the carb? There also a chance that the pulse fuel pump is clogged, due to the rubber diaphragms becoming rotted and coming apart. The fuel pump is the square bit on the side of the carb. Four screws a couple of diaphragms and a spring is all that's in there nothing magical about it. Give this a try and let us know what you find? Dan.

Rizzo Posted April 23, 2017 Author Report Share Posted April 23, 2017 Wow you guys are awesome with the replies. Luckily a local member has offered to have a look so hopefully we can get it going. The former owner has also told me he will look after getting it running but since he lives in Barrie hope this works first rather than figuring out how to get it to him Link to comment Share on other sites More sharing options...
fishboy Posted May 13, 2017 Report Share Posted May 13, 2017 curious...how does the story end? Link to comment Share on other sites More sharing options...
scugpg Posted May 14, 2017 Report Share Posted May 14, 2017 (edited) My guess is the carb jets are clogged. I had a 9.8 tohatsu a few years back that had this issue. Took out the jets and cleaned them out and ran like a champ after that. Doubt it's the thermostat or impeller. Would have to run a lot longer than that to shut off.... If it even has any time of thermal protection. Edited May 14, 2017 by Spooled Link to comment Share on other sites More sharing options...
Rizzo Posted May 14, 2017 Author Report Share Posted May 14, 2017 how the story ends..(I did a separate thread on this)....there was a ton of water in the gas tank the original owner gave me. Lesson learned,,,don't use someone else's gas! Freshtrax came over, took everything apart...we drained gas a couple of times...took carb apart twice... got rid of a whole bunch of gas...got er running and now she runs like a champ!

Rizzo Posted May 14, 2017 Author Report Share Posted May 14, 2017 ...and as far as impeller goes...it eventually kicks in...I think motor has a themorstat and needs time to warm up. Willl replace it sometime this summer as a preventative measure Link to comment Share on other sites More sharing options...
