Carb. Question 10 hp 62 Johnson

[mettyfish]

Actually my question applies to all carbs. How important is the little o ring gasket that goes in between the bowl and the jet standoff post in all carbs. It seems like a lot of carbs I open up this gasket is not in there.

Also need to know the beginning needle settings as I moved them when cleaning the carb. 62 10 hp Johnson

Thanks, Mettyfish

Not sure exactly what o-ring you're talkin about. Can you post a pic? Carbs vary quite a lot. Especially ones that old. Same for needle settings.

The boss gasket is VERY important, without it high speed flow can get messed up. I had a 18 hp in a month ago that didn`t have it, wouldn`t plane a boat, put it in and it flew after that. Try 1.5 turns on low speed, three quarter of a turn on the high.

Re: Carb. Question 10 hp 62 Johnson

thanks BK Thats what I thought. Its amazing how many carbs I come across that boss o ring is missing. Thanks for the needle valve settings. I will try that. Tell me which is which again though. High is on top or bottom.

What is the " jet standoff post", please?

Re: Carb. Question 10 hp 62 Johnson

On these motors everything is controlled from the bottom adjustment. There is an `outer ring` which has a link to the top needle (slow speed) the high speed is sitting at the end of the rod that is through the slow speed ring, this pic should clarify.

I think he means the nozzle, number 57, number 58 is the boss gasket.

Cool! I guess it's removable, huh.

Re: Carb. Question 10 hp 62 Johnson

it`s slotted and unscrews from the carb for cleaning.

In my 1957 the gasket marked 57 was cork, I think . It broke in my hands. The replacement comes in the rebuild kit whichI got from Laing for about $25.
