Suitable walbro-Aviastar 1.50 conversion
 

Hi all,I am converting a new in box aviastar 1.50 ive had for a few years to gas.I fitted a evolution 26/35 gt carb adapter, (after turning the stub down),heat insulater etc and fitted pressue nipple to crankcase to supply vacuum pulse to the carb adapter.Rcexl ignition fitted timed to 28 degrees btdc.
My question to those more knowledgeable in this area with regard to a carb that would work well with this engine is,
Would a Walbro WT610 be to much carb?.
I have a WT391-no checkvalve-11.1mm bore and
a WT610 with check valve with a bore of 13.49 mm in the box of spares,
Or perhaps some other walbro carb would be more suitable for this particular conversion?If so what part number walbro that is readily available should i look for?

I would use the 11mm carb, or another 11mm carb with an accelerator pump if you can find one.

Thanks av8tor1977,i'll have to do some cross referencing and searching.
Will try the 391 and see how it runs,was concerned it doesnt have the high speed check nozzle,but,it may work fine without issue.
