My snow blowing woes AGAIN

[Shuboxlover 482]

In reference to my OTHER post about this topic

http://www.wheelhorseforum.com/index.php?...topic=14101&hl=

well I narrowed it down....I pulled plug wires individually (inconclusive)

however....when I took the air cleaner off I noticed the carb was VERY frosty, and there was an ice ring underneath the choke plate as shown in the picture.

HOW DO I SOLVE THIS?????

Is it as simple as dumping heat in the gas, or is there another fix?

Yep, your carb is icing up. No, heet will most likely not fix this issue. How does the air come into the aircleaner? I know on my 520 it gets air from the blower housing which is preheated to some extent.

I believe mine comes into the air cleaner via the flywheel screen also but to say mine is preheated would be a far stretch of the imagination because it looks like the tube that goes up to the intake box doesn't even come close to getting warm via the engine heat. The carb was frosted up under the air intake. How the heck am I going to keep that warm?

This is worth a try, but is in no way guaranteed to solve the problem......

Try turning the air cleaner base around 180 degrees so the hole where the rubber tube comes up through is closer to the exhaust side of the engine. If that means drilling a few new holes in the base, then do what you have to do.

Don't worry about the rubber tube from the blower housing until it gets warmer. The flywheel is forcing the cold outside air into the air cleaner and it never has a chance to warm up on the Briggs twins.

If I get a chance, I'll check out my GT-1848 for better winterization ideas. I'm thinking that a preheater tube can be installed from the muffler shrouding to "meet up" with the hole in the bottom of the rotated air cleaner base.

Thanks TT, I would appreciate that.

For the time being, I have made what i guess one would call a "heat houser" I took foil tape (for duct work) and "taped" around the sides of the air cleaner and between the air cleaner and the muffler, in hopes that it will force warm air from the motor around the carb.

But I am up for any ideas.

Thanks

As long as you have eliminated that little rubber tube, I'd say you have made an improvement. :notworthy:

[Shuboxlover 482]

I have two little tubes (I presume from the crank case) and one big one from the shroud going into the air cleaner. Which one/ones should I eliminate?

[TT-(Moderator) 1,162]

The bigger tube that feeds fresh air into the air cleaner from the blower housing / flywheel is the one you want to remove. You can also tape over the hole in the blower housing and it won't hurt a thing.

I'm trying to convince myself to go out to the shop so I can check mine out. :notworthy:

pulling warm air into the intake from the exhaust manifold will fix the problem. my C-195 has an air cleaner with instructions (was a factory option from what i've read) to turn it in the winter so the intake is coming off the exhaust manifold.

our bulldozer also has an adjustable baffle to pull warm air in the winter.

i'm hoping my D doesn't ice up (my farm tractor does) but it isn't too drastic a fix to make a new intake tube.

I had C-175 with the same setup.

[Shuboxlover 482]

Do you know if they make that setup for a 16hp briggs? What exactly needs to be done in order to accomplish this?

My C195 and 417 both have the winter-summer air cleaners,Rick

the winter/summer air cleaner has a steel intake elbow, so you just rotate the whole cleaner so the elbow goes from sucking clear air to sucking air off the exhaust manifold. if your intake elbow is rubber (like the one on my D), i would try to fab one up and just put the intake end by the exhaust manifold. could use formed sheet material, a flexible metallic type hose, probably just about anything. it probably doesn't have to actually TOUCH the manifold, just be close.

what you have to do is move the air filter box so the hole is over the exhaust this will keep the heat on the carb and keep it from freezing up any questions call me :notworthy:
