Valve adjustment???

Yes, have seen frosty carbs more than once, most of the time when someone either modifies the heat box or swaps an engine set-up for warm weather on a blower with out removing the air filter and installing a heat box.

From the carb sounds I heard, it does sound like a stuck or sticky valve. The carb can only get throaty sounds like that if an intake valve is partially open, maybe stuck, or even more probably a small piece of carbon stuck between the valve and seat. Being a twin cylinder one cylinder can keep the engine running, and almost sound right, but the machine will have almost no power. I have seen this kind of situation when a valve seat moved because the engine overheated because the air screen on the flywheel was covered over with either chaff or ice snow mix.

Just curious if it sounded better after the temps got warmer......




My guess was going to be a leaking gasket, that's what it kind of sounds like to me.

BTW, it should be a single cylinder.

My tractor is a 15 hp single cylinder. Already said that in the first place (not trying to be an ***).

Warmer? I don't even know what warm is anymore. Lol.

I haven't had a chance to start it lately. It's been sitting since January 6, not enough gas to run it, can't afford it at the moment.

Just what are you using this tractor for snow removal? I run a snow blower on mime and this brings the engine up to full operating temperature even in this 0 degree weather. Yes gas can be pricey when moving snow, more so then cutting grass. If you don't already know it you are living in the wrong state if you don't like cold weather.

That's why I'm not running it. I only have enough gas to do a few driveways.
Haven't needed it since Jan 6.

Now don't bashful, just take your gas can down to the local gas station and fill it up. By the way, you had also better bring a 20 dollar bill along with you to pay for it. ouch :wink:
