fairholmes Posted January 22, 2010 Share Posted January 22, 2010 Hi all, after a bit of advice. My L plate 200 passed its test on Monday, and has now got a troubling issue. It has always fired up on the button, but since standing running on the ramp it has a problem. From cold she turns over fine but takes some turns to start, from immediate shut down she starts straight away, but if left more than 1/2 hour she is back to churning until finally firing up. Logic to me suggests air in the fuel system somewhere. Can anyone enlighten me on this one? Thanks Quote Link to comment Share on other sites More sharing options...
bobtail4x4 Posted January 22, 2010 Share Posted January 22, 2010 on a cold start, try priming the lift pump, if it starts ok,its air in the system, probably something got disturbed in the test? have a look at the sedimentor. Quote Link to comment Share on other sites More sharing options...

fairholmes Posted January 25, 2010 Author Share Posted January 25, 2010 Hi again Right, replaced fuel filter and primed up and she started well, in fact she runs better than before. However, still slow to start. I have yet to strip the sedimenter, but it seems likely that air or musk are in the fuel lines somewhere. Does anyone know if there is a particular area that would be a first place to check? Any help greatly appreciated as its driving me mad.............. Thanks in advance Quote Link to comment Share on other sites More sharing options...
BogMonster Posted January 25, 2010 Share Posted January 25, 2010 Check the metal fuel lines coming out of the tank for pinholes, if there is a pinhole in the suction side then it will suck in a steady stream of air bubbles but usually if that happens it will die at anything over idle Quote Link to comment Share on other sites More sharing options...
fairholmes Posted January 28, 2010 Author Share Posted January 28, 2010 Sorted!!! The metal fuel lines in and out of the sedimenter had corroded just sufficiently to 'bleed'. Quick bypass of the sedimenter and we are up and running. Thanks all Quote Link to comment Share on other sites More sharing options...
