Engine worked flawlessly last weekend. This Sat on first start attempt I got "ignition timeout" on first 3 attempts. 4th attempt the gas solenoid started clicking and sounded like the sparker from an old pulse jet. finally got a start on 4th attempt, but got long flame tail from butane.
I'm thinking solenoid is bad, but would like confirmation before replacing. Have you guys seen this before?

Thanks,
