Bike now running nicely, primary main jet changed to 145, pilot to 45. Mixture still slightly on rich side but acceleration is now smooth in all gears, no backfiring in deceleration and consumption halved to 20km per litre, eventually resolved problem & found duff pick up coil/harness. Resistance all good and insulation when measured; not good when tried to use; intermittent break in cable!! I also stripped down carbs when she refused to start and found broken mixture screw which I thought was the cause of rich running; replaced with help of Zac who has given much support. At the same time I stripped the carbs and found that the original EV27 carb had been replaced with an EV 30 and With the larger jets for for that carb. I would like to replace those with the correct 2 x 140 main jets and 46 Pilot jet to see if that reduces the rich running and bring the mixture screw back into play; it is fully seated and the bike runs ok with slightly sooty exhaust, however it does run! Bob Wright is checking his stock of jets as I type but if any one has any sparesIā€™d be happy to part with silver ( or Plastic).

Thanks Zack
