any help on checking reed valves, is this an easy check. i have a 115
that i was told possable bad reed valves. i do not beleave that but
would like to be sure before tearing down. i think fuel problem. good
compression all close to 120lb. rebuilt carbs, new fuel pump diaphram,
and water pump. motor hard starting, dies when in water after take
off, problem restarting. any help here????? thanks koz

There is no breather. Tired reeds will cause a some spit back through the
carbs as described.

Unless you have any BROKEN reeds , tired reeds will mostly only affect the
idle.

I think you need to make sure the carbs are set up correctly 1st. Start with
the idle screws 2 1/2 turns out and set them from there as per the manual.
If the carbs are truely rebuilt they should NOT be dripping gas unless the
motor is tilted up or your are squeezing the ball real hard to force gas
past the float needles to "pre-flood" it for easier starting.

You ought to take it to a mechanic that knows the inline 6 well. I say
90/10 odds your problem is not reeds.

You practically have to flood an inline six to cold start it.

this is a inline 6, three carbs. when testing the reeds, do i hold the
cardboard in front of the carbs? this has no breather i don't think. i
know that i am getting gas dripping out of carbs. if it is reeds, is
this worth replacing them, and has anybody replaced reeds on this
motor? any tricks? thanks

THANKS AGIAN, I MAY GET BACK WITH YOU BILL, YOU HAVE BEEN A GREAT
HELP. I AM REPLACING THE FUEL LINE AND BALL, AND CHANGING THE GAS WITH
ALL NEW AFTER I CLEAN THE TANK, THEN I WILL CHECK THE CARB
ADJUSTMENTS. YOU SAY YOU HAVE TO FLOOD IT TO COLD START IT? I KNOW ITS
A HARD STARTER.

Can you elaborate on "dies when in water after take off" ??

If the motor dies when it is running at some significant speed then the
problem is not going to be the reeds.

The reeds are the valves that prevent the gas/air mixture in the crankcase
from going back out the carburetors. Ideally,. the reeds lay flat against
the reed plate and form a perfect seal. As the reeds get old, however, they
tend to pick up a bit of a bend and/or warp. This allows them to leak a
substantial amount.

This is usually a problem only at idle. At higher RPMs, the amount of leak
is less noticeable and the higher pressures tend to force the reed closed.
If the engine was running OK at some RPM, there is little that a reed could
do that would cause it to just die.

Hard starting, poor idle and hesitation when accelerating is likely to be
reeds.

On some engines changing the reeds is a trivial task. On other engines you
have to take so much stuff off that it becomes a nightmare. If you can get
to them without too much effort I would just change them to eliminate one
source of problems.

i got it running rod, disconnected the fuel tank, ran a new line into
a fresh can of gas, hit it with a shot of starting fluid, and it ran,
and ran good. idled great.and would restart right back up. so i think
that i have bad gas in the 30 year old tank.so now i have to flush it
out. and it still starts very hard when cold. the true test is on the
lake. the last time i got it running in the driveway it ran good, took
it to the lake, and could not keep it running. it would start very
hard, then when hit wot it would stall. so i hape i found my problem,
the carbs do not drip fuel when it runs, and it sounds good. think i
found my problem, now i hope to make it start eaiser. thanks, koz

An easy test of the carbs is when your get it on water and get to running at
about 3000 rpms engage the choke.
1. Increases rpms - carbs are bad and running lean
2. Decreases rpms - everything should be ok or you have an ignition
problem.
3. Does nothing - you have a bad choke or you have a fuel starvation
problem.

yes, i have got a good running motor, flushed the tank, had to shave
some of the insulation off around the live wells to get it out. and
yep, bad gas. flushed the tank, replaced all fuel lines, and now it
runs good. waiting to get to a lake this week to test. the only thing
i have left is to fine tune the carbs, set at 2 1/2 turns on all
three. i herd i have to open up on a lake to adjust them. any thoughts
as to what i am adjusting too?? just the sound of the motor? and
anything else i should adjust while on the lake??? thanks for all the
help. those dealers!!!. i paid 180.00 for a poor diagnosis of the
problem.. when all it was was bad fuel.
