time for clarity!
count me in barry/brian...first things first.

only problem i have right now is that i'm not sure where the port/vee indicator is or how to read the sucker. i've done lots of searches on the forum, and have found conversations about the RIV and everything, but nothing with the basics.

seem to be (4) hex caps/bolts of (4) different sizes on the body of the IP...is it one of those? top right? top left? bottom left? bottom right?
can you help me locate the sucker?

and then after i take off the cap, i just stick my finger in the hole and turn the motor over by hand til i see a 'slot' in my little mirror or feel a gap/slot with my finger/fingernail?
