The connector should be marked for pin one and the last pin, normally in opposite corners. Then use meter to test for continuity.
Are you sure it is a solenoid and not a pump? Gas engines are fuel pumps. LP engines are solenoids.
Have you tried applying 12 volts DC to input to see if it works?

I did jump the solenoid and gen works, but to shut down, I had to remove the jump (12V to solenoid).

I wish of LP, but is gas. The shut off solenoid is at the bottom of carburetor.

You are somewhat correct, the spec H has both. Spec J does not have a solenoid. Look at pages 18-21.

At the end of my model# there is J, but the manual said is H. More confusion. All of them shows 15 pins, I count 17 in mine.

Spec letter is commonly in a separate block from model number.
Will look to see what I come up with.

Can you get the computer number off yours? Do not try to use from drawings.
Looking at a couple drawings, some of the pins are not used and on drawing that shows remote (fig 12-21) start indicates less wires and then jumpered at remote start/stop.
