[@mcwells48]

Excellent videos Leo I'm working on a 67 Johnson 40hp which is very similar. I appreciate how clear and thorough your videos are thanks

Nice video. Hope the new gasket solves the problem. Thanks for sharing.

Thanks, I'll have the answer posted on Tuesday, fingers crossed!

what would the right compression would be? i seen one post a guy got 95, top and bottom, another guy says 88 is perfect. honestly i'm just looking to have my 1952 idle at its very lowest speed, just creeping along to troll a minnow, not looking for top end speed. what would be acceptable when i do a compression test do you think?

According to my go-to Small Engine Doctor on YT, donyboy73, you want at least 90# or better to be a good runner. Cheers!

Hi, is it bad to run one of these motors without the bottom cowl?

[@lgallant]

No, if yours is missing, it's ok as these motors don't run hard enough to kick water up and hurt anything.
