Dellorto PHVA and PHBG tuning

[anttikauko]

I read on the forum the text made by Don K. Cortney ”An Alternative Method For Figuring Out Carburettor Tuning”

I have three Derbi Senda mopeds with 50 cc and 70 cc engines and I ride mainly on paths in a forest or on a uncultivated field. I have done a lot work with carburetors to get a nice pull from the idle to WOT. I feel some of my ideas for tuning the carburetor and are slightly different to D.K.C’s methods and I like hear the comments of the members.

These instructions seem good. Personally I have had great results by using this article on moped army for my PHBG carbs: www.mopedarmy.com/wiki/How_To_Tune_PHBG_Carburetors

for me, it helps that it is step by step and so prescriptive.
