Well done Terry, and thank you for making sure the weather is good for us in the days to come!!
Are you any good at finding air leaks in fuel systems? I did a 48 hour rest test on the engine (3 x 24 hour waits worked flawlessly) and... there was air in the fuel. Aaaaagh!!!!

You sure it's not the injector pump that's not the problem ? is it worth speaking to the previous owner ? Dunno what help /advice he can offer but he must of experienced the same problem.Jeff wrote:Well done Terry, and thank you for making sure the weather is good for us in the days to come!!

If the air in system is a big problem.try a complete revaluation of the system ie start by rigging an independent fuel supply direct to the injector pump from a clean can of fuel . If that's ok after a few days then move back to the next conn in the system and test for a few days . So on and so on .
It didn't do it last year when we had it. It's a new problem. And the air is deffo getting in somewhere in the vicinity of the final connections to, or on the injector pump.
The difference made by the gunk I applied to the last bleed screw was very very noticable, but I left the remnants of the copper washer in place as they were fused to the injector pump housing, so I'm wondering if a really really tiny leak is making its way under that. When my new washers arrive I'll clean that off completely and seat it down on a new washer.
It's not a massive problem now though - so long as we start the engine once every 24 hours it starts without hesitation. After 48 hours there's just a bit of a cough at first, then it's fine. It's not stopping us from starting up.
Just annoying really.
