Hi all can anyone point me in the right direction regarding jet sizes when using a 28mil phbh and expansion pipe with the GT 186 kit. I have looked on the GT site/manual but cant seem to find anything for this carb (unless im looking in wrong place)
Many thanks,Baz.

Jetting for the PHBH30 is below a 28mm version would be near identical, perhaps a little smaller on the main maybe 115 to start with.
Dellorto PHBH30 (caution standard version of this carb has restricted access to air screw and idle stop adjustment when fitted) Cable choke conversion Part number: 53003. Settings for open mouth with JL3 or KRP3 expansion chamber. Suggested jetting between 115 -125 main jet, AV266 - AV268 atomiser, X13 needle, 40 slide, 55 idle jet, Timing set at 17 degrees BTDC.
