Thought your email wasn't working.
Ok, so I used the email link on your "My Page".

Also, I have the "Illustrated Parts List" for
Model Series 287700, Type Numbers 0026 through 1290
For use on engines built before date code 02120200

Mine again is
Model # 287707 Type # 0224-01 Code # 960828ZD

Anyway, have studied that pretty close and can't find anything in there that looks like or is labeled as a compression release arm.
What part should I be looking for?
And any clues on deciphering the date code?
Do I have the right Illustrated Parts List?
Thanks

Note:
Looks like there were 3 different cam shafts for this model series and date code. And which one depends on the date code.

An fyi- 790400 (698492) is the cam for your engine. The arm is part of the cam.

I have instructions which include how to determine if you compression release is working.

Ok, just sent you an email Walt.

>>The arm is part of the cam.
Don't see anything on the cams in the diagrams - oh well.

Thanks all.

I found the date code info.
Those last 2 zeros (on the Illustrated Parts List) through me off and first google result said MMDDYY = WRONG.
http://www.ehow.com/how_5616636_read-briggs-stratton-date-code.html
The code is the manufacturing date and is read as follows:
YYMMDD & ASSEMBLY LINE AND MANUFACTURING PLANT

So the date is ok for the Illustrated Parts List.
Don't know if the Model # is though.

Here is a link that might be useful: Wrong Info

Paraphrased from Briggs.

{{gwi:317492}}

Yep, like I said.
The wrong info is MMDDYY.
The right info is YYMMDD & ASSEMBLY LINE AND MANUFACTURING PLANT.

Also, would that part number 790400 (698492) be the latest greatest version or the original duplicate?
If original, would it be better to opt for an improved version?

Thanks

Found a pic of similar cam with CR here:

I would like to know easiest way to find 1/4 past tdc

When the intake (lower) valve is actuated and closes- follow the piston up to the top of its travel and continue 1/4" as it starts to go back away from the top. Use a dowel or something similar and turn the engine clockwise as viewed from the top.

Remove valve cover,remove spark plug. Put a screwdriver in plug hole . Turn engine by hand watching screwdriver move and also the valves to determine which valve is open. To set tdc you want the intake valve to be open.For 1/4inch past TDC mark screwdriver and turn engine slow to 1/4 inch.

"To set tdc you want the intake valve to be open" You don't set the valves when they are "open". Valve lash or clearance can only be set when there is no contact between the valve stem and the rocker arm. If the valve is open that means the rocker arm is pushing the valve open.

Good to see you Larry. How's things by you?

I'm doing well Tom and I hope you are too. Please send me an email. Thank you
