I'm in need of getting the very small rubber o-ring on the idle jet for my blower. I can order the carb kit which it is part of. But as usual I want to find one locally so I can get my machine back together. So far I've struck out at 1 AutoZone, 1 Lowes, 1 power products dealer & 2 True Value hardware stores. Next I'll be trying a plumbing supply store. Any other suggestions?

Check around for a nearby Parker hydraulics store, they usually carry most sizes of o-rings. If you don't have a Parker store check with whoever supplies and repairs hydraulic hoses and fittings.

HArbor Freight has o ring collections in both sae and metric sizes. Not sure if they contain anything that small. I ordered my last supply of o rings on the Bay in bulk for about 50 cents apiece with fee shipping. MH

Do you have a neighborhood (scuba) dive shop? They usually have a lot of them for regulator repair and some do get tiny. Do you know the trade size number?

NAPA and other auto parts stores usually have a case that has O rings anywhere from 2" down to something that is hard to see. Go to the older hardware stores in your area. The older the better. They are the places to look for stuff like that. We have two old stores in our area and I can go there for knob and tube wiring parts s well as leather cups for wells and etc. They have those display cases full of O rings and other hard to find parts. Also, try your local small engine repair shop.

I'm going to be the pragmatist here. You've been to 4 stores so far and probably spent what 3-5 gallons of gas running around. Discounting your time as of no value, you've already likely spent more in gas and wear & tear on the vehicle than the cost of a carb kit. You could have used the o-ring and thrown the rest away and still be money ahead.

Nice to know of options but your time also has value as does the cost of driving. I know it sounds dumb but so does running all over the place unless you were going there anyway.

I admit I've done it too, but the older you get the less you want to run looking for something than just biting the bullet and doing it.

My 2 cents

PS - I think I've seen them before at Fleet Farm if you still want to try tracking down just the O-ring.

Carbs

If I end up buying a carb, can some confirm for me that this would be the correct one?

A131 MTD Troy Bilt Cub Cadet Snow Blower Carburetor 951 11303A 951 14023A | eBay
I can't honestly say whether that's the right one or not without seeing the original. I've bought a few carbs off Ebay before. What I did was have the current carb available to look at then started looking at carbs for the same size and make engine off the website. If the throttle, carb linkage and had the primer nipple, that's what I bought. I honestly have not had an issue doing that and most have been Oregon carbs. In fact one that was available but had the wrong choke on it but it was the closest to what I needed. Once I got it I took the choke mechanism off my old carb and put it on the new one and it worked perfect. I took it apart too to check it out and looked like a Tecumseh carb kit parts would work in it too.

Hope that helps.

Those are all great suggestions. Thanks guys.

HCBPH - I'm with you on all that.

Also, my machine's carb does not have the Carburetor Insulator (#132 in diagram on pg 33). Should I be concerned?

The download on the manual isn't working for me. Is that insulator you mention a gasket between the carb and block? If so, you do want it and can get it at almost any place that has Tecumseh parts. IIRC that last one I bought (about a yr ago or so) was maybe a dollar or two. It seals the carb to the block, so it is needed.

Thanks for trying, HCBPH.

It does work for me. The Sears Parts Direct page opens first then, a moment later the manual appears.

This insulator appears to be wide & metal like the carb. It looks to mount on the intake end of the carb between it & the heater box with a gasket on both ends of it. Definitely not there on mine. On mine, there is not another part or gasket between it & the heater box.

Something I noticed which seems like a bad design is, this heater box which is open at the bottom is located directly above the left side tire & it seems that if anything were to get flung off it could end up inside the carb.

I was basing that ebay carb by the part # that Sears lists for carb which is 951-11303A

You don't have to worry about this unless you go 10 mph + ;)

If the insulator is missing, are your mounting studs like one inch too long? Did someone replace the studs with shorter bolts?

I have no idea what #132 is but being it's in the schematic I'm assuming it's there for a reason. Sorry, no info here.

Studs do not seem to be too long.
I'm the original owner & those are the factory studs.

It does seem odd to me how exposed the intake end of the carb is. Almost seems like something more should be there. Seems weird to be able to see the choke plate when everything is assembled. But that could be cause I'm use to seeing an air filter there. This is my first experience on an engine that doesn't require one.

Part of Air Cleaner Assembly??

A couple days ago I was checking out the engines in Harbor Freight. Their engines had this insulator on them. It appears to be a part associated with the air cleaner assembly. So I'm thinking an engine without an air filter would not have this insulator on it. Can anyone confirm this?

Looking at these engines got me wondering....what do you guys do with the air cleaner assembly when repowering your machine with one of them?

Looks like Harbor Freight had the O-ring I needed. Thanks 43128 for that suggestion! I'll know for sure once I reassemble it.(Like Sarah Palin would say "I'll have to get back cha on that one" lol) Seems to be a metric sized one. Never knew till now that there are SAE & metric O-rings. Came in a 225pc kit for $8 on sale for $5 & had a 20% off coupon = $4. Not bad at all.
