H2C Idle - over run?
Posted: Fri May 15, 2026 11:07 am
Hi. Just got one of the H2C's going after some work - carbs etc. Starts fine and idles OK. If I push the revs up to 2500 or 3000, then let go, it takes 15 seconds or so for the revs to drop back down to the idle. Would anyone have an idea why please? Thanks. Nigel
