RE: Walbro/Zama 11mm carburetor list
AV8TOR Post #8 Can you explain the port timing thing. What about the intake port? Do you mill off the top of the piston there as well as near the exhaust port? If you mill of metal off piston top ...would that not lower compression? Do you have a photo of what this mill job would look like? Thanks Capt,n PS Keep up the good work
