I wanted to get a second opinion on my plugs. Running wot for 10min plug #1 is dry and plug #2 is barely wet. Both plugs are basically the same brown color. If it matters it was 80*F and I generally...
When you say one size do you mean going from 59 to 58 or from 59 down to next available size?

Factory jet is 59 for my carb but with 25hp intake it didn't like decelerating too fast back to idle. so based on your experience it sounds like 60 or 61 would be best?
I was going to try a 63...
Have you guys ever messed with the high speed jets? In my 28hp flat top carb (same dimensions as choked 76+ 30/35 carb) it came with .059" (59) jet but the flat top 30hp carb come with .067" (67D). ...
Anybody have any tips or tricks on removing the brass idle and high speed feed tubes that go through the venturi? Im going to bore my carb out but haven't figured out the best way to remove them....
After further investigation, it appears the difference is a small hose fitting above the fuel pump. I feel more relieved now. Thanks for the explanations!

The part numbers are different between the 1995 20-25hp and the 1995 30-35hp. Id rather not order one and pull mine off just to find its identical. Or has a dimension that can be easily modified.

Should there be a big enough difference to be worth swapping the 25hp cover for the 30hp cover?

Could someone explain what the bypass cover on an omc outboard does? all I can figure is that it is a vacuum chamber for the fuel pump? I noticed the 25hp and the 30hp 31.8 (in 1995) were different...
Thanks so much for that info! My carb is a newer (1995 28hp ) carb but has the same dimensions as the 76+ w/choke. I wonder why they changed diameters between "76+ w/choke" and "80's".

Just measured the throat at 1.5 and venturi at 1.35 of the 28 hp carb. Do you know what he 30hp carb diameters are? I couldn't cross reference the carb body but i thought on the 30hp carb it was...
Ive been researching for a while and decided to bite the bullet because it seems to be worth the upgrade. So I found a 28hp flat top carb for $85 and order the factory 30hp jets for it because I...
