Dodged a bullet. Intake wheezing.

[signsup]

Finally got my 2/27 engine running quietly enough to hear myself think and noticed a high pitched wheezing sound coming from the intake area. Felt around and did not notice any difference and thought for sure I had a bad manifold gasket or copper rings. Sprayed carb cleaner and brake cleaner and really did not identify the exact location of the wheezing, although it would occasionally bod down or fire up slightly.
This motor did have a stove pipe attached to it and I thought I would remove it to hald ID the issue. Upon removal of it, lo and behold, there was a mud daubers nest in the stove pipe that was, thankfully, vacant. Upon washing it out and running a wire brush through the stove pipe to clear out 97 years of memories it ran great upon reinstallation.
Quiet as a T.

Dodged that bullet.

Good news. I had that same problem with an old Farmall tractor that had been sitting a long time. It had a nest under the rain cap and down in the air cleaner. Same thing happened on the exhaust side with a near-new Kioti tractor, and I thought from the sound that the turbo was going out. Clearing out the dauber nests made a huge difference.

Had that happen to a small block chevy, mud dauber right down the double pumper. My bad, stored without an air filter. My bad again, kept cranking, trying to start until some of it got sucked in and locked a piston. Had to pull the head.
