Until further along, where I tried to turn it round.....gave it quite a bit of throttle as I was turning, and it started running very rough, coughed a bit of blue smoke, then eventually stalled....kicking it over again resulted in rough running for about 30 seconds and then it stalling again. Quite annoyed at this point, we managed to get it to drift to the towpath and tied it up....and operated the little hand pump on the lift pump which resulted in perfectly clean diesel..... After much head scratching, we kicked it over and it fired up straight away.....all the way back to the mooring...result!

Had a similar problem a few years ago, engine would run for a fairly long time then conk, need bleeding, then run for another week.

After a lot of head scrtaching, realised there was an air leak, diffilcult to locate, but under normal running was sucking a small amount of air until sufficient had build up to stall it. Used the lift pump to pressurise the system and check every pipe and joint, eventually found the main leak on the injector pump, but also found a few other small weeps!

As for stopping it, you do need a good seal on the air intake, and the re-breather can cause problems if there is any way air can get through!
