Thanks for the help ,checked the points and correct info ,they were about 10 thou not 20, had a bit of fun working out how to adjust through the window in flywheel,which to my knowledge was never explained in the old gregorys victa manual, but worked it out,and now purring like a kitten.
On another note, fibre washers used on old victas, i bought a good kit of fibre washers from aldi $4 and they fit the bottom of the old 18 carbys and the the drain bolt on crankcase, dont know about the inside washer under jet, but for four bucks 150 piece washer set.
