Trying to trouble shoot an acceleration lean problem on this set of carbs. So we stuck the GoPro on the back and took a quick test drive. Video confirmed that the pump doesn't squirt as readily/quickly as it should. Still working out the solution, but thought I'd share the video since it's mildly interesting.

Sounds and looks like you have a plugged idle circuit. Pull all of the jets and make sure they are clean by spraying carb cleaner through them. THEN, carefully remove each idle screw counting the turns so you don't have to set them up again. Take the little extension on the carb cleaner, stick it in the idle screw hole and spray. Then reassemble everything. Be careful not to munge the idle jet o-rings.
I like to spray the jets out on, in or near a white paper towel so I can see what junk comes out. The satisfaction of finding a little piece of junk is akin to popping a zit. The idle circuit is in play up close to 3000 RPM. When you get beyond that it seems to run better. |
