Worked on the carb today as i could see from the plug she was lean on idle and hard to start. A couple of discoveries:
- the stock PZ30 has a metal cap over the idle screw, you can twist it off with plier to reveal the idle screw (so stupid imo).
- there is no idle air/fuel mixture screw
- pilot is a 37 / main is a 102

Since I had my old stock PZ30 from the Brozz, i decided to use it instead. I used 2 shim washers under the needle, kept the 37 pilot (Brozz was a 34) and changed the main to a 110. Turned the a/f out 2.5 turns.
Started right up and a short ride reveals it to be much snappier and no deceleration popping!
