Patriot Cam Base Circle Size

Make sure the checker is on the base circle lobe when you are checking.
> tighten rocker with p-rod checker a little loose (short) to 22lbs
>unscrew the checker and make sure it fits in the rocker cup till you have 0 lash
> 0 lash is no wigly motion on the rocker (but not tight)
> take the rocker off and read your checker
> add .080 preload to that and voila, that is your p-rod length.
P-rods are made in .025 increaments so choose the closest one on the lower side to your measurement.
Expl: if you measured 7.440 with preload factored in, then 7.425 should be your choice.

good luck unscrewing the checker while it's tightened down in there......no room. still would like to know the base circle i know somebody has to have a patriot cam and can help a brotha out. though not like it matters much since it snowed 3 inches here today.
