Morning Guys.
Having problems with my 18mm delly on my 150 Special, so want to swap it for a 20mm one I have in the garage. Anyone running one with a 20mm, and if so , what jetting/slide are you using? Scoot is all standard with standard exhaust.
Cheers
Martin

My LI150S import from Italy had a 18mm on that was well worn so I put a 20mm on, I will check the jetting and let you know. My mate bought a Pacemaker new from the local dealer in 1966 and it came with a 20mm carb on. I am sure about this because I checked it over to find out why it was quicker than my standard LI150.
