Difficult starting

[agonda1]

1959 g/flash - starts easily from cold and runs perfect.Try to start again after say 20mins and it's very difficult but eventually will burst into life , but only then when throttle is open wide.Mag has been re-conditioned,timing correct,carb settings correct and no air leaks - what's going on ?Problem has existed for 2 years - plugs do seem a bit sooty

G'day Jim.
Sounds rich to me. Re-check the float height. Try a hotter plug.
But as most carb problems are electrical and vise versa it could be the condenser.
Cheers

Good thoughts.Mag has been overalled - could a condensor have been overlooked ? - will contact said person to query
Lived in Canberra 1n the late 1970's.Had a couple of bikes over there - honda cl350 and suzuki 350 gt triple = both went well

Forgetting to replace the condenser when rewinding the magneto sounds unlikely.


If the plugs are getting sooty, I think everything in the carb is not correct.

Always suspect a worn needle jet.

all jets + needle are new - just today i made non standard adjustment and things have improved including colour of plug  :-
needle groove no 2 - pilot screw out 4 turns

Hi,
Make sure the plugs and caps are non resistor types
There are /were a lot of poor quality condensers being fitted by mag reconditioners 
These usually fail totally though 

4 turns out is way outside the adjustment range
Presuming a monobloc carb? is the pilot jet tightened fully home before the cap is threaded on ??
