evening O wise ones,
following launch and normal niggles I ran engine to check for probs after top end overhaul, ran for about 1 hour under varying loads keeping eye on overheating and oil etc she ran nicely and I felt happy, huge mistake, the following happened;
1 revs dropped slightly and momentarilly [heard it]
2 revs returned to normal [perhaps 1 was imagination]
3 within 5 mins 1+ 2 very pronounced shut down did checks etc all ok start again 1+2 worse now engine seems to be labouring. No bad noises no steam no overheating stop engine rotate by hand all ok
4 symptoms are like heavy load not diesel probs
5 run her up revs freely and no noises just this labouring
6 noticed rev counter fed from alt is working intermitently
7 voltmeter went off scale
8 B--gg-r this engine off me on pbo forum
am convinced its not mechanical or diesel
any ideas
thanks
keith
