Reply To: Wisconsin M RBM poppet valve carb

[Buccaneer]

Guess I need to figure out how to get Sirrus radio in the garage, but
presumed the Wisconsin would run better listening to something
from the roaring 20’s? My tin garage and radio’s don’t seem
to get along, and most days only get the station 30 miles away.

I got the best results in starting, and longest run, with the
needle a quarter turn open, maybe a little more.
I actually took the poppet valve out once, and had no
flow out of the little valve seat passage, with the needle shut off.
At 1/4 turn open, I had a slow, but steady drip.
I believe I’ve flooded the engine more times than not in trying
to get it started, but part of the problem may have been the buzz coil.
The needle’s seat looked kind of “iffy”, and I actually took the
nut off the needle and tapped it gently with a brass hammer into the seat,
to see if I could improve the looks, and operation of the seat.
Best I can say, is that it does stop flow when the needle is seated.

After forgetting the tank fuel valve open the other night, and ending
up with gas all over the floor, and in every orifice of the motor,
I came to the conclusion that the poppet valve and seat could
use some improvement, but expect things would have to be
perfect on the seat to not let any gas leak by overnight.

All I know, I’m tired of doing the same thing over and over and getting
the same results, so nothing ventured, nothing gained.
Thanks for the tips!
