Hi all, I need some assistance with a Tecumseh 2-cycle, 3TPXS.0494ES (TC300)that is on a Troy-bilt mini tiller, Model 21A-128T063 sn 1B2890011 it has either a Walbro or a Tillotson carb, does not have a primer, I need to know what carb kit it would take for either carb or just the diaphragm kit. It is 100 miles away with no parts available so when I go I would like to be able to fix it. I got the usual, "It ran the last time I used it 2 years ago", it's my sister so be nice. Have a good one. Geo

 

Hi Geo, sorry, I don't know what diaphragm it will take. I just worked on one of those the other day and had a diaphragm for it, but I don't know which one it was. It had a tillotson carb on it if that helps. I just matched it up with a diaphragm I had on hand.

 

Here are Techumseh numbers.
632904 Diaphram
632907 Pump gasket
632908 Pump diaphram
632933 complete kit

 

Thanks a bunch guys. Have a good one. Geo
