Gentlemen, I stand corrected, in the sense that indeed everything is possible.

How do you match the described symptoms with the jumping camchain?

A

If the cam timing is advanced you generally can expect good and improved torque and power in the low range but lacking in the upper rpm range. The reverse would be true for retarded. It does not explain why the symptoms go away after 15 minutes, but based on Loony's assurances it is starting to sound like it may not entirely be a carb issue after all.

do a google search... everybody is basically reporting the same thing ... but why it clears after 15 min ....:(... it could be that there is more than one issue at fault. lets find something that is obviously wrong and work forward.

Hi All
 

Just to let you know I haven't given up on the problem, I've just got to spend less time on it. I'll get back on it in a few days. Thanks for all your help.
Cheers, Julian
