Default RE: 29cc or 30.5cc head kits for baja5b

I have a walbro 688 carb..High needle setting is 1 1/2 turn out from closed ..Low side needle is 1 1/4 out from closed...Sounds like you are fouling
plugs from oil /or bad mix ratio..try 32:1 mix.. 4oz oil to 1 gal of petro..need a good synthetic 2 stroke oil...Those are stock carb settings.. you will need to lean out a bit

I was having a low end bog with the walbro 668 carb..I just now switched to a walbro 813 carb. with modified plate,,there is no choke withis carb
it has a built in axcel pump to help low end bog for smoother eransition to mid range...I just got it installed and have yet to get it fired up..Getting late
and dark here..So I will be ready in the morning..I will let you know how it goes....AkA Slawhammer
Hope this helps..
EDIT: I also have CY29CC Engine
