Okay. I am ignorant.
Is it recommended to lubricate the slide in a 2T carburetor? I tried a new carburetor on the Kymco super 9, with no change.
Decided to put things back to where they were when it would run and rev. Disconnected the exhaust at the port, and re-installed the carburetor. I had to grind a relief to remove the cable from the slide 'lid' as the pokeys would not compress the spring(dirt in groove?), so the carb was permanent on the cable. Because of that, I decided to lubricate the slide when I put it into the carb.
Well, it started. I had been unable to get it to run for more than 15-20 seconds, except once, some time ago. This time, I placed a hand over the intake while kicking. It got wetted. I removed the spark plug, dried it using a piece of cloth, re-installed, and kicked.
It started. I was feeding the float bowl from a length of fuel line, and it was eating gas. I re-connected the enricher/byvalve wires to make the choke turn off(as if it was working...) and it kept running. I jazzed the throttle, and it kept running.
After ten minutes or so, after opening the door to let the smoke out, I tried to adjust the idle mix and speed. Oops. Somehow it got the idea that the throttle was wide open, and the rpms kept climbing. I choked it with my hand to keep it from winding out. Tried to fiddle with the idle mix/speed, to no avail. Finally choked it too much one time, and it died. I turned off the ignition and walked away.
My work(the original problem) was done. Ha! New rings, and gaskets, clean carb & fuel line... thought I was done months ago.
Now I have to figure out why it wanted to run away.(rpm)
I did use some motor oil on the slide, did re-connect the throttle cable, and tried to limit air coming in from cable connection.
I suppose I should re-connect the fuel line to the tank and add mix to the tank and give it a try.
What are the effects of sealing the slide with motor oil? I figure that is why it started to run, as nothing else, essentially, was changed but disconnecting the muffler.
Should I re-connect the muffler and see if it will run again? The idle sounded funky, not smooth, though the exhaust note was likely influencing my opinion. The note did change depending on how much fuel was in the 'tank' created by the 12" of fuel line. Or just connect the tank setup?
This thing is worse than a $100 (full boat retail NEW) McCullough chain saw. Won't start, won't idle, but you can saw if you can get it to run and know how to pull the throttle wide open, it seems. Too finicky. What have I missed in this soap opera length trial?
At least the seals and reeds are functional, right?
