Exhaust spring is "heavier" than the intake spring.
The Briggs 2HP (And 3HP) did not use a gear governor. They used a air controlled one. The flywheel would blow air onto that piece, regulating the speed. Remove the flywheel, and you'll find that little flappy piece of metal, connected on by the same screw using to hold the coil on.
No engine that was properly cared for will look old inside. On the contrary, it'll looks amazing.
Say sayre, do you happen to know if regular mail service (USPS, snail mail, stamps...?) would ship a single ring under a stamp?
Thanks... I'd gladly ship it by regular mail service, but when I shipped my friend 2 new set screws for his Max Torque clutch, when he recieved he, he found 2 holes in it and the screws gone
So I'm not sure if one of the machines chopped it up or such... but I'd try if you like.
