no vacuum on fuel side of engine - Craftsman rider
Model # is 247.288811.
I get nothing when trying to start. Have spark & fuel. Pressure at plug is 40 psi. I get nothing with starter fluid. Not even a pop.
Checked vacuum after removing intake manifold and there is NOTHING. Tested with the palm of my hand when cranking starter. I mean there is nothing. I had to check it myself after my son said there was nothing last night and I saw 40 psi at the spark plug hole this morning. No vacuum! Intake manifold removed for test.
Something must be up with the intake valve. Our next step is to take the motor apart.
Has anybody seen some psi at the plug and no vacuum at the intake? If so, what was wrong?
