Grumpy, all went well with the honda valve' amazing how a little valve could do this. The hole was definatley unblocked before reassembly, so i had a good outcome and funny enough I've got another sanli to do so hope I havn't got the same problem because I don't have any more honda valves to spare. Are they hard to get new ?
Thankyou again Grumpy ,you got me out of another pickle once again.
