fuel supply problem for inboard
 

I have just aquired an older style ski boat with a 202 engine and weber
carbie. On my first run out it coughed and spluttered but eventually we
got it up to 40mph. On the way back in it kept stalling under idle. We
decided to clean out the carbie and found a bit of muck in jets and
filters. Tried again, this time worse. Didn't even get 50m off shore
and almost flattened battery. Took petrol pump off...replaced pump, put
in fuel shut off valve...tried again. Still no joy...coughs and
splutters and cuts out under load. Any suggestions?

I forgot to mention that I have already put on a new fuel filter and
have really pulled the carbie apart and have blown out all the passages
in the carbie. Thanks for the suggestion of the replacement kit.

I would start with a good fuel filter to keep from reinfecting
yourself, then really clean the carb instead of trying to get lucky.
You should be able to find a kit. Tear it down and blow out all the
passages, replace the gaskets and needle (from the kit). Then blow out
the fuel lines after the filter and try again.

How do you know you don't have an ignition problem?

Take it to a professional to check it out.

Almost sounds like a sticking needle valve in the carb. Just cause you
"took it apart and blew out all the passages" doesnt mean you cured the
problem. Old, glazed fuel is hard to remove unless you soak the carb
body in carb cleaner for a day..... Your float could be "fuel-logged"
(not floating) as well.

Your symptoms sound much like those I had when my coil went bad. You might
check it out.

Change fuel filter & water seperator. Clean/refurb carbie.

Clean & gap spark plugs.

Replace points & condensor, set points gap/dwell. Replace old weak coil.

Replace plug wires & coil wire. Check ballast resistor for specs.

Use fresh gas.

older 202/3.3 motors had a habit of skipping the timing gear on the
dizzy when old. check to see is its plastic gear if so get a gear of a
old oil pump (any holden red/blue six) and replace with that.
Sounds majorly like the idle fuel circuit is blocked.
The stromberg i know but the webber was not a standard holden carby
and i hate carbys at the best of times.
It is also a good idea to change the timing gear its self if its NOT
alloy.. original was fiber (runs quieter) but was a habit of stripping
at the worst times
If you want to improve the spark ect replace the dizzy/coil cap and
leads with a electronic one from any of the blue six range....bolts
straight in no wiring mods needed.......you Will need to upgrade the
leads and plugs tho coz the old ones WILL die with the newer electronic
dizzy.

managed a holden wrecking yard 8 1/2 years
