If the float needle has the most minute marking on it, it could fail. I
would suggest getting new needles and seats for both carbs. They are not
expensive.

HI Group,

The sickie is a 1978 Chrysler, 2 cycle, 70 HP outboard. The motors
been gone through and re-gasketed prior to my entry into its world. I
finished the motor by going through all the externals to ensure it's up
to snuff per the motor manual.

Build a motor stand to test and run the motor out of the water but with
water hose cooling supplied of course. The motor fired off and ran for
around a minute but then started pushing gasoline out the card throats.
I went back in and checked the float settings and the needle and seat
but found nothing abnormal. Also checked the distributor timing but it
was right on the money.

Any suggestions on what to look for next?

Don,

Thanks for the advice in new needles and seats. Is there a good source
for these types of older parts? I've been looking on the internet and
found some suppliers but the best people may not be on the web.

Thanks again for the help,
Mike, Pensacola

There may be part # on the parts. A small engine type might have an
assortment on hand. Varnish can build up in the hole for the needle,
causing it to stick. Clean with a cotton swab and camp stove gas. Dry
with air. A proper carb man would clean out every orifice with high
pressure air.

I have a badly worn carb that would not behave until I wired snug
external O rings above and below the butterfly throttle shaft with
brass snare wire. It was so loose it wiggled and upset the mixture any
where near idle, or, it seems, whenever it chose to.
