wrist pin- which way?

Post by Bill Hermsted » Sat Jul 06, 2013 1:20 pm

hi- should the closed end of the wrist pin face the exhaust port in a stock AH 58? Please clue me in, as these kinds of details are not always in the manuals.
Thanks, Bill

Bill, The Tecumseh Mechanics Manual calls for the open end of the wrist pin to be on the exhaust side.

thanks, Louie! The only clue in my manual is an exploded view of a Super showing what seems to be the closed end of pin towards flywheel side { Tecumseh split crankcase models}. I wasn't sure if this alone was enough info.
Shown on the last page, by the way, is a listing of speed items you could order for the AH 58-61 and 82, right from Tecumseh! Single exhaust port cylinder and pinned ring piston for 81-82. Twelve reed intake for 81-82.Thin ring pistons and drilled rod {all} There's even a dual intake with progressive carb linkage.
Tecumseh really did do their homework back in the day.
