Default VM26-606 baseline

I'm trying to dial in my VM26. Starts fine, idles fine, boggy if you give it throttle. Anyone have a baseline? I'm at sea level currently 50-60 degrees F, 17.5 pilot, 140 main, needle clip second from the top.

wildbob I would get a good assortment of main jets and jet up until you get a puff of black smoke under wot acceleration. This would put you rich on your jetting and simply back off jets until it feels good and then get a new plug and do a plug check.

Best plug check:
Warm up and ride the buggy with the old plug. Once fully warm install new plug.
Run the buggy at wot on a long straight run ( keep it at wot for as long as possible )
Kill the ignition and let the buggy stop.
Pull the plug and check for color. Light tan is what your after. Any lighter jet up, any darker jet down.
