List,
thanks for your respective replies. I was indeed using a lightweight oil in
the dampeners- changing to engine oil as some recommended along with sorting
the linkage, did solve some of the problems I was having. Still have
extremely hard starting when warm, however, but I think I've found the cause.
After a run today, I removed the pistons to change to the richer BAX needles
that were supplied with the carbs on purchase (incidentally, engine runs MUCH
better with the BAX needles no 2500-4000 rpm hestiation now). When lifting
the piston/needle assembly out, petrol started to gush and spurt out of the
jet and flooded the carb body at an alarming rate. Duplicated this situation
many times. This is probably what is causing my hard starting when warm. I
immediately disassembled the front carb and it was fine, no flooding. Why do
you think that this is happening to the rear carb only? If the fuel system
pressure was too high, it would be happening to both carbs (incidentally, I
am running the stock mechanical fuel pump). List, your collective wisdom
please, as I've sworn not to touch the carbs without hearing from you first!
Cheers and Regards
Geoff
P.S.: Sounds obvious, but pump not running when this happens!
