about bloody time......changed the metering head, still misfired, checked the injectors......took ages to get them out.
put my old ht leads on, started her up and took one ht lead of at a time. As i took the second one of the engine went to stall, i let it click a few times on the top of the spark plug then put it back on.....and hey PRESTO

no misfire, running nicley....just need to turn the revs down.

cheers for the help lads....took almost 2months of hell but looks ok now...........till next week...lol
