Hi,

I have checked the points, timing, plugs and valve clearances and all appears to be fine. Runs like a dream but when dropping down to tickover sometimes it pops and cuts out. It restarts Ok and ticksover is normally OK. Also sometimes tickover holds at 1200 rpm and then slowly falls. Before I pull the carbs apart again I wonder how important are the rubber sleeves that go over the ends of the cables and on to the carbies? Mine are perished and cracked. Can this cause an air leak which might be the cause of my problem?

Kind regards
Mike
 
Mike,

I don't really know how important the rubber sleeves on the choke plungers are, but I suspect that this is not your problem.
Check the plunger seals and that the plungers are free to move and not caught. If they are ok then your problem could be elsewhere.

I had a similar problem with the engine gradually fading away - classic weak mixture symptoms. In my case I adjusted the primary screws and everything was fine.
With any luck that will be your problem - 3 or 4 minutes fiddling and you are done.
 
What ignition are you running? Standard points setup?

Just asking...

Just thought maybe check the mechanical advance / retard is working OK. Not gummed up, springs OK etc. Can do some weird stuff that sounds a bit like your problem.

Quick 'n easy to do.

Whatever.

If your worried about an air leak try the light spray of starter fluid around the carbs trick.Dont go nuts around the spark plugs or airfulter through
