I have a 2012 i bought with zero miles in april and have just over 650 miles on it. was going to do the post 600 mile oil change tomorrow but last night on the ride home motor started bogging and then stalled completely. now will only run with the choke on and stalls when the throttle is opened. did i get some bad gas or is it something else and what do i do? it is still under the factory warranty.

Did you fuel up just before the change?

Has the fuel in the tank been there for a month or more?

Did you switch the petcock to PRIME and see if it runs any better?

Talked to the dealer and he suspected bad gas. suggested i drain the carb and see what happens and that did the trick. running fine but am headed to put in a tank of fresh gas. he suggested adding some Heet in the red bottle to each tank of gas. is this something that is a good idea?

No need to treat gas. Run it. Now,if it's gonna sit and it's in a vented container it's gonna suck water in and evaporate off the stuff that.makes it go BOOM and it won't run worth a crap.

McDave,   I see your from Minn, Where. Perhaps I could help.
(If close enough)  I am about 25-30 miles West of the TC area.

1st, No Heat, If you want to add, their are so many other better things.
'SeaFoam", or, 'Stabel', both all over the place here.
Any Fleet/Farm, Wally World, Almost ANY, ''auto' parts place.

2nd. Use,  'NON-OXY', gas. Here in Minn, the, 'supposed' 10% ethanol, is running 12-14%. Even the gas stations don't know the exact %.
So use, 'NON-OXY' gas.  We are lucky here, Non-Oxy, is available in a  LOT of places.  

3rd. If you don't fill up portable tanks, and fill gas at home.
Then go to gas stations that have, 'dedicated', Non-Oxy pumps.  That way you get all, Non-Oxy' gas.

If it is a 'select', a grade, pump. Consider, what the person before you put in. A Pint or Quart, of that, 'selection' remains in the pump/hose.
If you are pumping 10 + gallons. A PT/QT, of 12% (+/-) gas doesn't add up to much. But if you are pumping, 1.5-2 gallons, it adds up.
AND, What if the person before you, pumped  E-85  ??????

I use portable tanks. (5 gal, 'jerry' cans).
If it is a, 'select', a grade.  I run a  Gal in the truck,
Then fill the tanks. That way I  Know, what is coming out of the hose,
is, all, 'Non-Oxy'.

What dealer did you go to?   I have been looking at a few of, 'NEW', 12/13 S40's.  Heinen in Osseo seem to have the best deals.
You got a new one, you use the correct oil, RPM's high enough, Correct break in, (Old Style). It will last a  LONG  time.

Just got a  PM from you, Know exactly where you are.  
Waconia,  here, about 45 Miles apart.

I did find, some, 'Red-Line' additive, (for the oil),
You buy a gallon jug of  Rotella, I'll put, 4 Oz in, and you are good to go.
Until you find some, 'Red-Line".

Ya didn't hurt nothing in that ICE, Just put in 'Good' gas.
Break in in correctly, and use 'High Zink', oil.
And that ICE will last a long time.

thankyou all. a lot of good advice here.i think there is a station here in town with a dedicated non oxy hose. i think for a start i'll give that a try.

I drained the carb and put in fresh gas and it seems to be running fine.
