Tecumseh engine problem

    Bought a new snow thrower last year, and have had this problem since day
    one.

    The engine is a Tecumseh HMSK 80-110 on a Troy Bilt Storm snow thrower. It
    starts just fine, but pops out of the exhaust as it's running. Then at
    times, it will run very rough, with the idle going up and down, then stall.
    I find that if I play with the choke, I can usually keep it from stalling.

    So, it looks like some kind of gas flow problem or maybe a timing problem. I
    plan on replacing the spark plug, but have no clue if there are any
    adjustments I can make on the carb (or how to get the cover off! This is a
    Troy Bilt Thrower).

    If responding to me directly, please take out "REMOVE" from my e-mail
    address.

    Thanks!

    I would guess it is a timing problem. You need to pull the flywheel to see
    if the key is slightly damaged.

    Any chance you didn't summerize it properly and there's a little water
    in the fuel tank which occassionally finds its way into the carb?

    You might try adding a small amount of gas tank "de-icer" to the fuel
    and see if that helps.

    This was happening when it was new last year. I bought it in October, and
    the first snow was in Dec. Yeah, I should have addresses it before now
    (winter starting) but you know how that goes sometimes.

    I'll give that a try. Is there anything I can merely add to the gas to clean
    the carb? I'm handy with this stuff, but not to the detail of cleaning a
    carb.

    One thing I totally forgot to mention. I recall this happening last year.
    When priming the carb, I found that sometimes some gas would come out from
    the carb area. I know this probably means there's an air leak or something.

    Sorry for not mentioning it sooner before replies, but it happened last year
    and just slipped my mind. I have to take the cover off the engine (the cover
    that Troy Bilt puts on) and see if I can see where the gas is coming from.
    I'll report back on this.

    Thanks again for all the replies.

    Update: I got the cover off and started it up. It runs fine at first, but
    had to play with the choke to keep it going. It will run ok after it's kept
    going with the right choke setting, except for some popping out of the
    exaust. I noticed a few things:

    o In a previous post, I mentioned that gas comes out of the carb area when
    using the primer. I find that the gas comes out of the air intake (correct
    term??) after about 5 pushes. This may be normal, but I don't see it
    mentioned in the manual.

    o One time, the engine, just sitting there idling, the idle would start to
    increase and decrease, and then the engine stalls. If I prime the carb
    again, it starts again on the first pull. While it was stalling I quickly
    adjusted the choke to see if it would make a difference. No difference at
    all. Almost as if the carb was not getting any air (not the case) or the
    carb wasn't getting any gas. Just like I turned off the key.

    o I notice that if I run the engine at full throttle, it runs a lot rougher
    (pops out of the exhaust) than if I were to run it something a little slower
    than full. With the right choke adj at a slower RPM, the engine seems to run
    ok (less popping). So, this may be my fix for now, but shouldn't be this
    way.

    o According the Tecumseh owner's manual, there's a bowl drain at the bottom
    of the bowl. I notice this collects small amounts of gas as it's running.
    Could it be leaking air into the carb?

    Let me ask this. To clean the bowl, do I just need to remove the nut at the
    bottom of the bowl to remove it? I'd also like to try to set the carb
    settings to, I believe, 1 1/2 turns, but I have no clue where the screws
    are. I see one that looks like it has a grey cap on it.

    Thanks again!

    To me popping in the exhaust indicates that the intake valve is still open
    when the gas ignites. Maybe my idea of popping is different. I am thinking
    of a small backfire.

    It does not fall into one of these recalled engines does it?

    I guess you can call it a small backfire. It does just sound like it's
    missing.

    Have you tried adjusting the mixture screw that is at the bottom of the bowl
    under the carburetor? I had similar symptoms as you--rough running, needed
    choke to keep it going, poor low speed running (stalling). Turn the screw
    all the way in--don't tighten it too hard against the seat. Back it out
    about 1 1/2 turns. Make small adjustments from that setting until there is
    a good balance between the high speed and low speeds.

    No, but I'll give that a try as well and see what happens. Thanks!
