Oil Leak --- Bottom of 1971 Tecumseh

I have an oil leak at the bottom of my 7hp Tecumseh with the oil pooling where the engine mounting bolts are. I thought the problems were at the breather cover, but that does not seem to be the case. Anything I can check to diagnose the oil coming from the bottom of the block?

jmho,.... unless you are a purist and want to keep the machine all original, repower it. other than that , remove all the shrouding and have a look to see if there's any hidden issues.

Hello and welcome to SBF GKSki. I would clean off all the oil and then check the drain plug, the sump gasket which is between the two engine halves for leakage, or the oil seal around the crank shaft. If neither is the cause, you may have a hairline crack that is leaking. The Tecumseh service manual can be found here-

Experience is something you don't get until just after you need it.

Hi GK Ski
The oil drain plug or cap. the oil breather tube, or what others said.
