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?
