:( Hi there,My prize & joy has running problems??? It starts but runs only on FULL throttle very , very unevenly, backfiring and Rough. It doesn't idle. All this hapened a few days ago just out of the blue. Up till then no problems for the last year. I've emptied the carbs/tank & replaced the fuel.....No water in it. I've taken the coils out & tested them....Plenty of spark. Those two little alloy fluted things under the seat haven't got hot or lost any of their tar.The leads and caps going to the Spark plugs work. What should I do now???Please help

:D Thank you Johnj. If I spray that aerosol 'start-you-bastrd' directly down each carby throat and if it then runs better.....that will prove your theory. I am reluctant to start pulling those four babies all apart for cleaning if I could possibly help it Thank you.

It's the little nooks and crannies that need the cleaning though.
