Ok Something isn't right. I grabbed a LM body, used a different diaphragm, different primer cap, different needles, checked the decomp for carbon, put in a cj8 and tested, tried different combos of washers, cleaned jet, checked starter o ring, changed inlet o rings, checked fuel flow and it all made absolutely no bloody difference
If I hold the diaphragm back (with cap off) it will idle to the point of stalling
Next steps are ripping a carby off one of my other ones and putting a good known carby on it or cut the spring
I reckon its a governing issue - sometimes if I blew into the governor port on the cap, there was a air leak, I managed to get a great seal, but the cable is snagging (must be slightly warped) so will have to remove a washer. Ran out of time tonight - legal noise restriction 7pm
Both the cams I was trying with were the short legged versions - one seemed to cause the stop pins to actuate a lot lower down on the throttle control
