While I was on a roll with this engine I decided to give these automatic carby's some attention.

I found grumpy's thread very useful:
https://www.outdoorking-forum.com.au/forum/ubbthreads.php?ubb=showflat&Number=22526As I have never checked for warping or preloaded the diaphragm. That is why I have 4 sitting here, I have one engine here that runs great, but just would not start with auto choke or Vacujet carby. (I ended up putting a Pulsajet with a fuel primer on it).
So I have serviced them all now, I ended up with 2 good ones and have to get some diaphragms for the other 2.
