Reply To: Wisconsin M RBM poppet valve carb

PMT2, in my case, the poppet valve guide is worn badly and not uniformly,
and the valve stem indicates very little wear with the micrometer.
If I make an oversize valve and stem, I’d still have to ream out
the valve guide hole first, and still would have the problem with
reaming it square with the valve seat. Not sure how I would accomplish
that with the carb is attached to the cylinder, unless some kind of guide
that set in the valve seat was fabricated.

I’m curious to know “how” and “what” material you used to make a new
poppet valve, and was it made in one or two pieces?

Before I get carried away with reworking the mixer, I’ll explore fuel
flow further.

Tubs, As mentioned before, I did find some crud in the fuel system
a while back. I had the top of the tank off during the original
refurbishment, and everything was thoroughly cleaned and the
tank was coated with “Red Coat”….. it looks red anyway.
What I can’t remember if there’s a strainer in the tank, or not
even sure if one if feasible. I’ll keep playing with it!

Thanks for the replies.
