PWK carb jetting links...

Postby spiderwebb » Thu Mar 07, 2013 9:58 pm

some of these are for dellorto and also lambrettas... look around and see what you can find that helps you in the jetting dark arts

Heat can be due to advanced timing and not jetting so check the timing is right asap ... lorto.html ... tuning.htm ... eedles.pdf

here is the basic jetting overlap

use a 40 idle or above and a needle that works in the 2nd or 3rd clip position... the needle taper steepness is going to effect which clip position works at all along with the main since they both "overlap" @ 3/4th throttle.

Be Safe = watch your temps and make sure you CDI is retarding to the desired timing #... as those CDI's fail they can revert back to a advanced timing # that would melt your piston fast...!!
