Dellorto PBHG throttle drum kit

• For PHBG 16-21mm carburetors
• PHBG 50: 5.75mm air intake
  
• Also for replica carburetors

A small cutaway creates a greater vacuum and consequently causes a larger amount of fuel to be drawn up through the atomizer... a lower slide cutaway results in enrichment and vice versa. PHBG 50 is the largest cutaway.

Included:

• Throttle drum
• Throttle needle
• Throttle drum spring
• Throttle needle locking plate
