where could I find tecumseh engine specs for an old-fashioned tecumseh engine. specs for the oil control ring compression rings and other specs.
Answers: I would search out online by your model number. I have a TVS-90 or something. One of the parts websites have a PDF file beside complete instructions on various models of Tech. Engines. (Technician's Handbook #692509)
I also found complete diagrams and parts list.
Rings
After the cylinder bore diameter has be checked and
is acceptable to do again, the ring end cranny should be
checked using new rings. Place a unusual compression ring
squarely in the center of the ring travel nouns. Use the
piston upside down to push the ring down (diag. 28) and
measure the cleft with a feeler evaluate. The ring end tear
must be within the specification to hold adequate grease
control (diag. 29). This procedure will assure correct piston
ring end break measurement. Ring side clearance should
also be checked beside a feeler gauge when using unmarked
rings with an dated piston (diag. 27).
Replace the rings in sets and install the piston, rings,
and rod assembly within the cylinder bore with the ring run out
gaps staggered. When installing clean rings in a used
cylinder, the cylinder wall should be de-glazed using a
commercially available de-glazing tool or hone.

Use a ring expander to remove and replace the rings. Do
not spread the rings too all-embracing or breakage will result.
The top compression ring has an inside chamfer, this
chamfer must facade UP. If the second compression ring
has an inside chamfer, the chamfer must facade DOWN in
adjectives engines except for HM100 and TVM220 engines where
the chamfer face UP. If there is a serration on the outside
diameter, the notch go DOWN.
The oil control ring can be installed near either side up.
The expander (if equipped) ending gap and the ring extension
gap should be staggered (diag. 30).
Emission Rings
Used on TVS, LEV, H35, VLV, HM80 and TVXL195
engines that comply near emission standards. These rings
own a narrower width and a different profile (barrel faced).
The underside of the grease control ring utilizes a coil type
expander.
These rings conform better to the cylinder allowing for
better oil control by wipe the cylinder wall cleaner. The
coiled expander ring helps create a more uniform nouns
on the cylinder wall which gives a more consistent
distribution of grease. NOTE: The use of these rings on a
standard non-emission piston will cause ring breakage
due to its wider ring grooves.
Connecting Rods
Some engine models enjoy offset piston pins (not
centered) to centralize the combustion force on the piston.
Engine models LAV50, HM70, HM80, HHM80, HM100,
TVM170,195, 220, enjoy offset pistons. When installing
the connecting rod to the piston it is imperative that the
rod be installed correctly. The piston used on these models
will own either an arrow stamped above the piston pin
hole, a number style on the inside of the piston skirt or
an arrow stamped on the top of the piston (diag. 32 &
33). All other engine models use a centered piston pin. If
the piston does not have an arrow or number type inside,
the piston can be installed in any direction on the
connecting rod. On all engine models, the game marks
on the connecting rod must align and frontage out when
installing the assembly in the engine (diag. 34 & 35).
The arrow on the top of the piston must point toward the
valve when installing it in the cylinder (diag. 32). The
inside cast number (if present) must face toward the
long side of the connecting rod. If in that is an arrow on
the side of the piston, the arrow must point toward the
short side of the connecting rod. (diag. 32).
On horizontal shaft engines, oil dippers are attached to
the bottom connecting rod bolt. Some engines own the
oil dipper pattern in the rod trilby. Consult the specification
chart for the proper rod bolt torque when installing the
cap. The rod bolts should be torqued within 50 inch pound
(5.5 Nm) increments until the specified torque is achieved
