Pilot jets are too small. His engine combo was different than yours so try the 22.5's first.

I have had a look at the jets in the carbs.

Main jet 135
Pilot jet 17.5
Fuel screw 1/2 turn
Needle jet looks like 8?
need a magnifying glass.

I obviously need to strip these completely.

needle - 9chyo-99 clip on 4th notch from top

the needle is.... 9chy6 on the 4th clip from the bottom or one down from the top. No mention of 9chy"O" - "99" on the needle.

thanks

The normal position of the needle is groove#3 from the top (middle position). Yours is 2 grooves leaner than standard. I'd suggest trying the needle in groove #3 and see how it runs.

Hanging up

Yes, get the larger pilots and try the raised needle clip position and don't forget to sync them.
A note, usually, but not always, the hanging up and slow to return to idle is a sign of being lean. There are other factors as well, but this usually it after you made sure not kinked cables and dirt in the carbs.
