I would recommend that you go to either the B&S website or one which sells parts on line and download a breakdown of you engine. It would greatly help you to understand the parts and what you are looking for.

Thanks, Rivets. I searched around tonight for a blowup diagram of the internal engine. Didn't find anything usable. Anyone have any tips on this?

The flyweight on the flywheel looks like a 1 1/2" finger near the gear on the camshaft. When rotated moves a small half moon rod that bumps the intake valve off of its seat for starting. the spinning flywheel causes the flyweight to move out for running and the spring returns it to its resting position when the engine is shut off for starting the next time.

Sounds like the pieces that you found are from a broken flyweight.

I think that IL means on the camshaft, not the flywheel.

I meant to say on the camshaft not the flywheel. sorry for the miss communication. Murphy of Murphy's law has been plaguing mean for about 3 days now. He usually sticks around about a week before moving on.

Wednesday was doing the camshaft broken compression release weight problem and went to open the new sump gasket package and the paper package tore wrong and tore the gasket in two. Yesterday was getting ready to put a new battery in a WE261 riding mower and the battery I got from the Poulan distributor had superseded to a incorrect battery, currently waiting on new battery and call tag for incorrect battery to be sent back. Also yesterday was going to put a new diaphragm on a small push mower and one of the carb mounting screws that bolts in to the fuel tank caught the edge of the diaprhagm and tore it. Customer came to pick up his rider yesterday and the voltage regulator quit at start up so I had to change it with the customer waiting.
