i do indeed... but check this out:

went to autozone and rented a compression gauge (cuz mine is at home) to test compression. the first one i got worked fine for cylinder one, but then the hose popped off the fitting in the spark plug thread, so i had to go get another one. the gauge on the second one didnt seal on the hose, so i had to use some electrical tape to get the quick-connect to seat, but it seemed to be holding pressure ok... maybe....

heres the numbers, from #1-4:
30-50-40-50

and with a capful of oil, they jumped to somewhere about:
75-90-65-75

so, my motor is completely shot according to this gauge. BUT, when i checked it with the first gauge (cylinder one only, before it broke) it was holding steady at 150. so, either the second gauge was shit, or my headgasket has a big chunk flapping in the breeze that likes to re-seat itself on occasion.

the thing is, it runs ok... stalls alot, idles pretty bad, but has decent power.

so ima check it once i get home on next tues, and then prob rebuild it completely...

***EDIT***
just for reference, the standard for the B18B1 is 199 psi, the minimum is 140 psi, and the max variation is 28 psi...
