carb kits for Tecumseh

[frankp]

Hello, I'm working on a Bolens Snowblower with a Tecumseh modeh H70 130124A ser 1139D. I did a kerosene soak and replaced the orings on the bowl and cleanoout button on the bottom of the bowl. I started on stopped the engine several times in the morning with no leaks. When the customer came to pick it up in the afternoon the cleanout button leaked. I had allready explained to customer that i just did a rought kerosine soak and used two gaskets for my spare parts. I did not charge him for this and explained that it wasn't a complete carb service but it did seem to work ok this morning. He asked me to look into getting a complete carb kit. The snow blower is old but in great shape. I found on Jacks small eng service kit 631793 for $83 plus $10 shipping. i have several P/N 6311978 and 632347 kits in my shop. Can I use the kits I have?

Partstree indicates that the carburetor kit is PN 31840 for both the original carburetor and the service carburetor.

huh? $83 for a carb kit? are you kidding me? I wish I could get those prices for that kit, I'd be rich. Probably the price you were seeing was a complete carburetor.. and $83 is about right for an aftermarket one - OEM carbs are a tad bit more pricey - 80 to 120 bucks a pop - In the case of 631793, which replaces old carb 631459 OEM carb will run you about $147 , so the "kit" you found would actually be a complete carburetor assembly, aftermarket (likely Oregon or Stens) version.

If the carb is original to the engine, it should take a 31840 kit (under 15 bucks, usually) - if your only concern is the bowl drain, you would want 27136A (about 6 - 10 bucks OEM, somewhere around there, and they are available in aftermarket versions, but much harder to install due to a shorter stem)

If it runs good and just needs bowl drain kit - 27136A and bowl gaskets (631028, 27110A) you'll be far better off with those than replacing a perfectly good carburetor with an aftermarket one - Personally, I've had spotty results using aftermarket carburetors - so much so that we just won't use them unless absolutely necessary... Others have had excellent results with them, so could be I just had the bad luck to get the "bad ones" out of the distributor batch..

Thanks for the help. I guess the 83 bucks was for a servive carb. Do you think i can use the P/N 631978 or P/N 632347 kits I have? Replacing that little oring on the drain looks a little tricky. Today I just slipped an oring from inside the bowl. Taking the spring loaded clip off the outside the bowl to remove the stem looks a little tricky with a good chance of breaking the clip. The replacement bowl might be the way I have to go.

Went to my local parts store and the owner had just the gasket for the bottom drain. In fact, he installed it for me in front of the cash reqister, I think just to make me look foolish. $1.27 plus maine state sales tax, which is a bummer as I live in tax free New Hampshire. Oh well, on to the next stumbling block. Thanks again for the light at the end of the tunnel.
