Kawasakis rule.

With most of the problems buttoned up, I took the rover for a 'speed test'.
BTW
These things can't speed, so don't worry about calling the sherrifs office.
I got the carb adjusted again, warmed the engine some and took off.
Accelerated good, shifted good, but after the first stop sign she got up to '40 ish'
and started sputtering. Hmmph. Turned her around and limped home with the engine barely sputtering at idle.

OK, Drained the last gallon of gas and lo and behold... crap from the tank came out. Its got to be varnish from the top corner of the tank that was missed. I strained the fuel, and poured it back thru through to wash out the rest of the crap in the bottom. It came out clean. Yay.
Put another gallon of fresh gas in and took off again. And it did the same thing. Except this time on the turn around the engine completely died. Dead. Nada.
I could spray carb cleaner into the carb and get it to fire for a couple of seconds, but it wouldn't run.

While pushing it downhill a guy on a Kawasaki four wheeler pulls up with a rope and asks "need a tow?". Not being the humble type I accepted. (Thanks to Brian)
The rover was pulled back the 1/2 mile to the driveway at a leisurely 7mph according to the speedo.
At home, the fuel line to the carb came off and the engine was cranked. A smidge of fuel came out only. Pulled and cleaned the rochester which had a little crud in it, cleaned the fuel pump bowl which had a little sediment in it, and fuel still wouldn't pump. Finally blew compressed air into the gas line and a bunch of crap came pouring out followed by clear gas. All is well, need to find a sock for the fuel pickup tube.
