checking your compression

[tav]

i checked the comp. on my 175 Johnson but i checked one plug at a time and didn't put the
the throttle at WOT...... at this point i got 90 on all 6 plug. probably not the
right waY TO DO IT.

so what would you think the diff would be if i took all plugs out and checked with it in WOT,
THINK IT MIGHT CHANGE FOR THE BETTER. oopps caps. is this the right way to do it?

warm engine,plugs removed and throttle wide open for best results.
