Brand new 100 with the reg up front. Anything but idle is great. High speed set, but was having a lot of trouble dialing in the idle (yes I have read the procedure, and as far as I know following it correctly). The engine surges at idle and within 45 sec to 1 min. dies, setting at 2000rpm, but since it's surging so much it doesn't stay there. One thing to note is that there seems to be a lot of air bubbles coming from the reg to carb line. None coming into the reg (hose is new and tight). Air leak in the reg? if you watch the bubbles the surging seems to match the bubbles coming thru. It only takes a click or two up throttle to stop the surge, also the bubbles stop, conincidence? FYI it's mounted on a Hyde soft mount, but I've never had problems with the old 110s on Hyde mounts.
What do you think Troy?
