OK. "They say" not to respond to your own topic, as people will assume it's been solved.
Not solved. Went through the process yesterday with someone who knows more about such rigs than I do.
Located the air intake under the center console. But no sign that, even though Amazon appears to sell choke cables, there is any provision for a choke on this machine.
We put in some drygas, cleaned up the spark plug, hooked up a jumper cable so the power would not run out, and repeatedly tried started fluid and alternately pumping the pedal and not pumping the pedal. (No smell of gas as in flooding.)
A couple of stutters, very minor, but no sense it was going to turn over.
This forum doesn't seem programmed to indicate whether anyone has read a post, so I dunno.
If you have any suggestions before I have to wrestle it onto the trailer and down to the shop, I would be grateful.
