Thanks Blumbly but I've already done as you suggested. The valve was open and it closed when I sucked on it.
I even swapped it over with one that was on an operating engine but it made no difference.
Over the years, it would appear that Victa mucked around with the design of the internals on the G$ / Lm carburetta.
I now have 4-carburettas stripped down and there are subtle differences in the design of the internals.
One interesting observation was the change in the length to the vane on the cam. I have two cams with long vanes and two cams with significantly shorter vanes. I'd post a picture if I had one but I'm sure you understand to what I'm referring?
The poppette design has also changed - I have two with no profile under the sealing lip and two with porting under the lip.
I cannot detect any change to the designs of the lifter?? With regard to the body design, I have one that has small nozzle attached to the fuel spray hole .... I guess it was done to improve air / fuel mixing in the carby throat and three carbys without the internal nozzle on the spray hole.
So as I said in my earlier post, I think I've mixed up a number of parts from different models but its also clear that Victa had issues with the carby from day 1 otherwise they wouldn't have stuffed around with the design. This view seems to be supported by NormK's above post.
Still not sure which way to turn except by purchasing an entire new complete carby but it goes against the grain if get my drift .... hate being beaten by a lump of plastic!!
