Well I got my short block for that Crapsman vac cart. Usually short blocks come with a packet of all required gaskets. I got all the gaskets but the head gasket. Inside was a paper staing since this engine is used on more than one piece of equipment and made to different specs for OEM, consult with your servicing dealer for correct head gasket. Ok, Sears can not tell me anything other than Sears part number for gasket, no cross referrence to a Tec gasket........but odds are Tech part number is on the Sears package......Can't get anay info from Tech as I called them, and my local dealers that handle Tech don't even have this engine model listed other than its Sears Specific.........and therefore do not have any IPB's...........After rumaging through the box the short block came in, I found yet another envelope contrary to what the paper in the first envelope stated. Inside this envelope were not 1, not 2 not 3 but a total of 4 headgaskets.......and a warning. Improper headgasket will result in valves contacting cylinder head when at operating rpm / temperature. Consult proper manual for use of proper gasket. So evidently its all in the head and valve lash so it still leaves me in the dark as to what gasket to use. There is only .005 thickness difference on three of them and .010" on the 4th. All appear to be identical except for the slight difference in thickness.
It also stated improper gasket will cause engine to lack power due to lowered compression ratio. Hell with only .010" difference between the thickest and thinnest gasket, I doubnt it would amaount to much as I seriously doubt that these engines are built to that critical of design and specs. Nothing like habving to deal with Sears and their crap and then Throw Techumseh and their crap in the same pot and try and figure it all out..........I looked at manuals covering this series of family of engines, and none of them cover this model as its Sears specific, so evidently its all smoke and mirrows or Sears is bound and determined to keep any relavent info a top secret!
