Last night I removed the carbs I had on it & tried to see if the different spacing of the bsr36 would fit.... no problems or buggering about with inlets - they popped on with a wiggle! With a little lathe work even got the original choke pull working with them.
I'm waiting now for 147.5 mains & 20 pilots to turn up.. I have no idea what to do with the other intermediate jet ( 3 jets is a new one for me) but they are bench synced & needles on bottom clip.
Weekend will be first fire up depending on postman.
