My 235 doesn't have the down draft tube, I did clean out the PVC valve while I was cleaning the manifold. The old fittings were nearly clogged it only had a pinhead size opening. I didn’t think it even needed a PVC valve, I guess I will replace that while I am at it.
I kind of figured it was normal. I was used to this on the old air cooled VW engines. I used to be a VW guy until I saw the light. | | |
