carb float

[Cadillac-ack-ack]

The type II carb on my '62 40 HP lark looks to be in very good condition. The red-ish brown hard coating on the cork is hard and intact however it is very sloppy at it's attachment to the brass tang making any kind of accurate adjustment difficult. Is this wrong or just simply something that has to be worked around? I'm thinking of washing it well with detergent and using J.B. Weld to secure it better. - Pete

if you don't go for a new one...


I have cripped tangs some on smaller motor floats and applied gelled..crazy glue


seems to hold so far

dry the float before applying crazy glue & don't use carb cleaner it will dissolve the coating if it a cork floatl

They still make them, y'know. New ones have a different coating than the originals, to withstand today's fuels.

Well I did see one at MarineEngines and it looked identical to mine, same coating appearance. What's on mine is intact, just that the tang is loosey-goosey. I believe I'll use regular set J.B. as it is impervious to gas varieties and even carb cleaners. Also thin enough so that it will ooze into the tang crimps before setting up. Kind of surprised the early one aren't brass. - Pete

Hm-m-m-m, let me think. Did OMC ever use brass floats? Possibly way back before my time. I'm only 81. Seriously, the old cork floats were coated with orange shellac. Alcohol dissolves shellac. The new ones have some kind of epoxy-like coating, I don't know exactly what it is.

EDIT: Oh yeah, now I remember, the old Tillotson MD carbs has brass floats. They often leaked and filled with gas.

The epoxy did the trick as far as creating a good solid union between the tang and float. I was able to adjust it to spec with only a slight bending of the tang. At first, before I secured the float & tang, holding the carb upside-down allowed the float to actual hit the carb body without the needle ever closing the inlet. Surprised it ran as well as I recall it did. Explains the black plugs though. - Pete
