OK thanks Grumpy and Mark I must have done something right as it is now running.Didn't get a good test in as it was getting late,but it did run and idle.At least until it smoked me out of the garage.So I guess my next question is why all the smoke,hopefully nothing bad.I did notice (due to sitting for who knows how long)that the pipes with the filters did have some dry chunky stuff on them.I'm guessing that wouldn't have helped.Generally the rest of the carby was OK not great just OK,and I did blow it out with the air hose.
