This is a spin-off of my other post. I was planning on converting my 50cc back to 30cc or if I could just put a pink cam on both?

If they both have the same cam(pink or smaller) they both discharge the same amount of fuel...........correct????

Thanks!

The pink cam is standard for the 30cc pump. The large brown cam is standard for the 50cc pump. I guess you could use the pink cam for the 50cc, but you'll lose pump volume for each stroke it takes.

That's kinda what I was looking for. I wanted to have the same shot as the front without having to switch over to a 30cc pump, not sure if it'll work though???? I think the arms are different on the pumps????

What ya think????

Something similiar to a factory 750 calibration for initial fire up, we had this carb on a friends 400 and it was too much shot. I'm still trying to figure out why they come that way?????

I'm thinking now that 700/800 where primarly used for tunnel and blower applications even thought they list the carb as general use. It has the same calibration has there blower line of carbs.


I do have a 30cc setup so I might just switch over.
