Twin H WA-1 carb question

trdrew

I have a Twin-H setup with the manifold & carbs that was given to me some time ago, and I had hoped to get around to retrofitting it to my '52 Hornet. Upon closer inspection, I've realized it is a Wasp setup because it has the #990 WA-1 carbs instead of the #968 WA-1 carbs that the Hornet used. Is it possible to re-jet the #990 carbs to use them on the 308 Hornet?

Thanks, Tom

The 990 carbs for the 262 have a smaller throttle plate and base stud spacing will be closer together than the hornet as well as jetting. The manifold is the same with the exception of closer mounting studs and the size of the throttle bore.
