my accord with 8.8.1 comp reads about 155psi across the board while my girls minime reads 210psi and its about 10.1. you cant really go by what the compresssion tester says.

it depends how you test it... if you just pull the plug wires and test... it washes the cylinders down with gas and what not... i believe (could be wrong) if yuo do it the right why and stop the gas... it reads higher

finding a concrete block to stand on while working underneath the hood (easy)

taking off the oversized K&N round filter (easy)

removing the linkages (easy)

unscrewing the hoseclamps for the fuel supply line (easy)

pulling off pcv and dizzy vac lines (easy)

taking off the 4 bolts with a half inch socket and a few extensions (easy)

having to crawl up into the motor and reach behind the carb to unbolt the power brake booster fitting with a 5/8" wrench that I'm sure I put way too tight last time I was working on the truck (kinda a bitch)

i always use a clamp and screwdriver to hold my boosters on... point the dealie to the outside makes its easier too

Re:compression?
 
what dealie?

I try and use hard brakes lines in every application on that truck. My luck is I would drive over a cedar tree and it would rip off the rubber lines.

I still need to redo the grill to make it so I can run over trees with ease.
