built a load of these.... PHBH 30 with JL3 Curly Pipe.... 4.8 final drive... just a great ride, pulls from low and revs out....

Plenty people using this carb on these engines too, and the jetting info is all very close. Doesnt drink much fuel either
Hi old post
But can you remember the jetting used on this m8?

I can't comment on the kit, but hot starting problems due to using Dell'Orto's with an air hose is another reason that I dislike the PH range. They flood so easily, whereas Dell'Orto's proper two stroke carbs are good, though ridiculously expensive. That said, I have the choice of VH through VHB/C's from 30 to 39 mm.

However, the PWK's from Koso, OKO & the like are a natural choice as they are inexpensive, set-up friendly & so air filter friendly........if of adequate size.

Your jetting details doesn't mention pilots. With piston ported, I have found down to about 32 is best, whereas TS reed valve engines require about 50 or so ;)
