On a Euro spec 110 engine I'm in two minds about the merits or otherwise of plugging the vacuum retard line. It retards the timing at idle and cuts out as the vacuum drops when the throttle is opened and the engine is under load........ BUT..
does it result in a conflict with the advance vacuum when running on a light throttle
Ie., on the highway ? ? I realise that its' function is to raise the idle speed when the Air Con is on by blocking the vacuum to the distributor. The static timing is 12% BTDC and the engine feels ok on the road. Sean

If it feels OK on the road why mess with it, I'm sure the engineers in Germany have designed it that way for a good reason.

:cool: I'm mindful of the comment to the teen who was eager to improve his Honda V Tech Engine and was asked what more did he know than 40,000 Honda Engineers !
