Nearside mirror fixed. some progress with vent seal - Found some 1/8' adhesive backed foam- tried gluing a strip to the seal for the rear edge but it wouldnt stick. Applied it to the rer edge of the glass - should work. The top seal that folds wrongly when closing the vent is pretty much done for, might have to live with that.
Other negative on last trip was very unreliable idle. on checking closely and reading the manual (19.15.02),I notice that I can lift the nearside carb off idle (<1/16) and the offside carb linkage moves, BUT stays on its idle stop. The manual says there is a locking screw that sets the clearance (.006) between a plate and a pin - this screw is tight, but the free play above remains. To me the way the screw affects the clearance at the pin is not clear. Looking at the parts book there is a bush mentioned (607800), that,if worn, could produce the play I am seeing. The carbs have had new jets, needle&seats and choke O rings recently, but I did not dismantle them any further than needed for that work.
Anybody have any ides or suggestions please?
Update - after removing the interconnect link it looks like wear in the bush mentioned above is allowing the plate with the ball joint fitted to move without moving the throttle shaft.
