Hi Geoff.
Sorryabout that when you get to my age you do forget things ;; I did
find the problem ;;as you mentioned must have been the viscosity ( always
wanted to know what that meant ) the problem was there was a shortage of
thread on the needle shaft wich tensioned enough to seal for water but not
for gin ( SORRY ;; metholhydrate ) so I added another washer and ''O" ring
and that did the trick ran the engine this morning and all was fine until
the clack valve washer gave way under 70 psi ;; now that is fixed also.
Funny thing though I ran my new engine yesterday and had trouble with
the clack ;;was not opening and the boiler ran dry ( that is also now
fixed ) .
Thanks for your comments Geoff very much appreciated.
Regards Graham >S
