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?

HI Group,
have you checked to see if your floats still float at the correct position

Cracked or unseated inlet valves?

Brian Whatcott Altus OK

Brian,

Do you mean the reed valves that are in the intake manifold assembly?
If so, I didn't get into these as they were installed with new gaskets
and I assumed they were checked out and no problems found by the prior
owner.

If these are what you are think the problem is I'll certainly tear into
them after your positive response

Thanks, Mike

Tango,

I've set the float position per the manual in both the open and closed
position using the dimensions indicated for my model. However, I have
not tried to physicaly float the "float" to see if the gas flow is shut
off. I did use my lung power to determine if the float valve seated
while the float was upside-down. I could not hear any leakage and
could feel pressure build as I slowly operated the float manually.

Please advise how to check for float position on the bench. Your help
is certainly apreciated.

Thanks, Mike

I'd revisit the reed valves to make sure they are sealing properly.

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.

I have had a fixing screw come loose and hold an inlet reed valve
open. At the cost of pulling the carbs off to look, I'd think it's
worth a look?

Brian Whatcott Altus OK

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

Brian & Tennis Shoes,

It seems you both think alike for the problem being the reed valves.
Since I've pulled the carbs off to check the floats, I might as well go
a little deeper. The manual has lots of possible problems shown such
as bent, unseated, dirty, rusted, etc. Thats where I'm heading next
besides new needles and seats.

Thanks again,
Mike, Pensacola
