Been running the blue sta-bil in it from the start. Have had it for a year now, just under 50 hrs. I did not take it out April thru August, but I started it once a month, but when I started it in September, it was probably a month and 1 or 2 weeks, it was then it started not running so good. It would spitter sput, but it runs, and after I took her out and ran her a few times she started running better. It would not idle, for the first time yesterday I tried to turn the idle up, 1 minute video below, you can see it idles, but rpms drop to 1,000, then go to 1500...

Carburetor messed up from ethanol?

Don't know what is wrong but there are places you can get gas without ethanol. Might be worth buying a few gas cans to keep it on hand.

That is exactly what it is. Remove your carb from top of motor and drop the bowl from the bottom of it. Thoroughly clean the bowl and your pilot (idle) and main jets. Be careful not to disturb the position of the float when reassembling. Also, always disconnect fuel line from motor and run gas completely out when motor will sit for a while. Ethanol is da debil.

Have you dumped the old gas, sure you have already, but if not start with new gas. If you let it sit up for a month or longer it will separate unless you use an additive. I always run gas with ethanol and have no issues but I never let mine sit for more than two weeks without running it. I do not have a water separator on mine either like some guys have.
Remember it is nothing more than a lawnmower engine, My lawnmower goes 4 months sitting up with never being used and runs fine when I start it up in the spring however I never leave gas in it thru the winter.
Might want to check your plugs and valve lash, once everything is fine there you may have a clogged jet in the carb from it sitting up so long. You can either clean the carb and jets or buy a new take off carb from Boat Dr. or Mudbuddy(BPS) for around $80 which would be easier and maybe cheaper than working on yours.
But remember if you let it sit up this could happen again, cranking them once a month and using them will prevent most of these issues.

If you want someone to fix it for you send me a PM and I will give you a name of someone local.

Yup that's carb issue.. have you done a full service on it yet also? air filter, fuel filter, oil/oilfilter. spark plugs? also id drain the tank, flush the lines and clean the carb. even with stabil that gas is only good for about 30days

Which fuel pump do you have? On mine the fuel pump gave me all kinds of crazy until I went all electric, bypassing the mechanical. Life was all good from then on. Then problem with the mud boats is fuel is up front, 18 to 20 feet of fuel line and 3 feet of rise to the motor. I should say, the problem with mine and a lot of others. Once I did that I was good to go and even gained 2 mph to boot.

I found a place that I buy no alcohol gasoline has in 5 gallon containers. It is expensive at at 8bucks a gallon. I treat it with blue stabil and use only that for chainsaws and all other small engines.

I have always heard to run the fuel out but I don't know the effectiveness of this practice. You can't run all the fuel out to make a dry storage situation. If you can't run it all out then why bother.

it runs it out of the jet which is usually the main problem imo.. now if you do this and then tilt the motor at a different angle it could then soak the jet back in gas

I have put over 125 hours on my most recent motor, Vanguard, the last 2 seasons and have never had a fuel problem, my last motor was a Kohler and it never had fuel problems either, never ran a water separator on either.
The problem is lack of use, if you let any motor sit up regardless of fuel there will be some issues, ethanol just makes the issue worse because it can separate. Also you may have to deal with carbon buildup in the carb, key to these motors is running them often, at least crank them once a month and do not use gas older than a month old if you are not going to run them in the summer.

Same thing happens with guys in the spring at the local boat ramps with outboards, they let those boats sit all winter long then have problems when they try to run them in the spring. Clogged carbs, bad gas, rotted fuel lines from ethanol, and all other issues.

Yeah, it was my 7hp Subaru-Robin EX21, on my Momarsh. That was last year, I tried to clean it myself, it leaked like crazy when I put it back on, took it to a lawn mower shop in Garland, it leaked at little gas then and still does a little now (not as much, it got better over the year), but runs great. Hunted it this weekend. Love hunting that boat.

I made a schedule to start both my boats every month over the offseason, and went a little longer than a month on the mud buddy, and that messed it up. Live and learn, I thought since a ran the sta-bil in it that it would be ok, but I guess not.
