K&b 3.5 ss needle adjustment

also inspect the upper bearing housing area VERY CLOSELY.. if you see ANY spider cracking you will have this issue. Some times you can not see this unless you remove the part

Also if you can find a sealed or shielded bearing for the top next to the starter cone, that may help temporarily....face the seal outwards.

Not exactly the same but gives you an idea of how a liquid / vapor seal works...
Basically oil film is the final seal.

Its all about the seal.. if the oil has to seal up a bad bearing then you have this very issue.

then.. tank location.. is it lower in the boat?

Grim

The tank sits on the floor of the radio compartment. I’d lay it’s a good 1 1/2 lower than the carb inlet

Ok great I’ll take it all apart and check them all. Thank you very much for your help fellas

They sound like they need the bearings replaced!

Grim

Hey grim I just got new bearings from k&b. None of them have seals is that normal?

 

[Grimracer]
