Default RE: Quadra 52 won't run under 3500 HELP


ORIGINAL: jimcork1

Thank you Rich,, I have a few more steps on the Zama and if they don't work I will order the wab carb.

Interesting though the WT210B carb intake is almost 1/2" compared to the 11/16 on the ZAMA. My current testing is using a restrictor plate to reduce the intake to 3/8 then 1/2". I have found better idle with the restrictor plate and only 200 rpm drop off of top end. Thanks again. Jim
The WT-201B is the standard carb on the DA-50 and Brillelli 366 plus many other engines so its plenty big enough. It does have an external pressure pulse line that should be noted. You could also use a WT-76A or B which is very similar but has the pulse port drilled to the carb mounting flange. That carb was used on the Taurus 52 and several Brison engines.
