[AT] Cub--shouldn't have broken my resolution....

[George Willer]

John,

A hole in the exhaust side of the manifold is possible, but since the
tractor runs on two there can't be a hole in the intake side.  It would be
the same as an intake valve stuck open... not enough vacuum for any cylinder
to run.

Here's how bad the exhaust side can be and the engine still run:

If the intake side of the manifold were obstructed it would have shown up in
the compression test.  Mud daubers obstructing the exhaust side?  My bet is
the spark isn't happening at the right time.

We have a good therapy department at the Willer Home for Elderly Cubs.  ;-)
