Hi all,
New to the site and in need of some help. Was working on the daughters boat today and ran into trouble!! after changing the fuel filter on her Saab model G powered narrow boat bled system and finally got it to start, this is a fairly old engine 1973 and always takes an age to start anyway 30+ seconds of cranking at best. Switched off to go and get a temp transmitter from a motor spares shop. On returm about 45mins fitted the transmitter and finally restarted only left the fuel cock closed and ran dry again. Since then have been unable to start it!! Have stripped the injector cleaned and rebuilt no go, have bled the system thoroughly, even removed the head anealed the gasket and rebuilt still no go. The piston and bore looked in fair to good condition, paraffin tested the valve seats while head was off. The only thing I can't gaurantee is the fuel, the fuel was from a canal side pump. Is this particular engine susceptible to poor fuel or is there something I should know about these engines?? some quirky knack.
Also has anyone the technical info (or know where to get it) for this engine torque settings tappet gaps the usual stuff manual if poss, and common faults, anything at all really. I've run out of ideas and she's run out of battery and waiting for a recharge before trying again with fresh fuel.
Thanks, Brendan from Cannock
