Hi again folks,
Thanks very much for all your input to-date regarding my little fuel problem – all very much appreciated.
I am due to take the boat out again this coming weekend so I will run through the various points suggested. I though that I would also but a new portable tank with new fuel lines and primer bulb and try that out. Hopefully that will determine whether the engine is the problem or the boat’s existing fuel supply system. (Jace – I did take all the filler pipes apart recently to get the battery out
and checked over the cap – seemed OK)
I also had a chat with Andy Clark of The Bosun’s Mate (www.bosunsmate.co.uk
) whose first question was “When was the fuel system last serviced?” My answer, I’m afraid, was “Ahhh”
. He did think that the problem was probably with the fuel pump, either the check valves or the diaphragm split or gone hard. (Well done JW) He is sending me a service kit for the pump which, he recommends, is done every year along with the water pump impeller. He also said that the carbs/float chambers may be gummed up with crud from old oil laying in there over winter when the petrol has evaporated.
Tiger, thanks for your comments on the mixture – unfortunatley the engine adds it’s own oil so I can’t adjust the mix.
Stuart, thanks for the link – looks like a few hours are needed to trawl through the posts.
Will report back next week – once again, many thanks for the info so far.
