mattylad Posted January 7, 2005 Report Share Posted January 7, 2005 Are there any differences between carbs fitted to two strokes and 4 strokes? For example I have a spare Mikuni originally fitted to a Beta Zero, can I fit it to a four stroke honda engine? I understand the jetting may need changing but is there any other differences I need to be aware of. I ask because I seem to remember that Amal concentrics are engine type specific.

subira Posted January 7, 2005 Report Share Posted January 7, 2005 I think its down to jetting and not type, I have a 22mm Dellorto PHBL on my Cub - which looks identical in every way (apart from the bore ) to the 26mm version found on many of the modern bikes. I checked Dellorto 'Carburator Book' and it doesn't differentiate between engine types for the PHBL. This might not be the best example but there are a lot of Cubs using this carb.
