Yes I had noticed he doesn't hang about....bit like your good self Jerv ;)

Ok, 110 rod, 3mm packer and leave the port timings standard, 16/46 with the Li 150 gears, 7000 Augusto.

What about the PWK 30, too small?

Cheers folks

30mm carb would be fine but you know my reservations about copy PWKs. Why are there always people trying to sell them too :?:

PWK floats are, as you know, temperamental. Someone posted in the last couple of weeks about the size of the float bowl on PWKs being problematic on thirsty tuned Lammies. I'd be interested to see a comparison between the PWK and PHBH float bowl as at the point the needle valve closes :idea:

It's a BGM PWK so hopefully better quality that the Viet versions. I did read the comment on here about the size of float bowl so that needs looking into but float wise, i've never had a problem with my other ScootRs pwk but I have had problems (as have quite a few others) with the PHBH ones.
