My book says 150 and my old one had 145 all across when I replaced it
with a lower mileage one.

A compression test tells only a small part of the story you should have do a
leak down test on every cylinder but what do I know?

Dont know what you drive, but my mechanic has me use a product called BG Carbon
Cleaner (aprox $25 a can) for my fuel injected car, one cylinder was reading a lot
lower than the others. He suspected carbon buildup. One can of the cleaner and it
cleared right up and they all read very close the last time I had him check it.

I got hooked on "Carbon Guard". My neighbor used to be an instructor @ OMC
(they make Johnson boat engines). My Scout was spitting & coughing because
the #8 cylinder was oil fouling. He brought over a couple of bottles for me
to try. He poured a full bottle down the carb & said to use one oz/15gal of
gas in the tank. It was still pretty bad for about 2 tankfuls after that & I
was getting ready to just give up & rebuild it. I was low on money & didn't
want to but it seemed as if I just didn't have any other choice. AND
THEN......................it was a miracle. I was coming home from work, it
was dark & I was tired, & all of a sudden the engine started bucking, &
backfiring. I didn't think I was going to make it home & began to look for a
place to coast to a stop on the side of the road. As quickly as it started
spitting & choking, it just, all of a sudden smoothed out & purred. Swear to
God - I ---- you not..........It won't run more than 2 tanks of gas without
it. I have a 32 gal tank & put an oz or 2 every time I fill up. I use it
once a month or so in the other vehicles. It works for me - costs
$10.00/12oz btl - & you only use 1oz/15gal - and you get it @ any johnson
outboard dealer
