I have just recently purchased a Scott 1929 Flying Squirrel, my first Scott but not first 2-stroke or pre war machine by any stretch.
After standing for any length of time I can put the fuel on & start the bike first kick no bother, then after running for however long the bike will not restart with the kick-start (not even a sputter) and will have to be bump-started down the street.
The carburettor seems to leak fuel as if the float needle is passing or the level is too high though there is only one position and I have tried grinding the needle surface in with fine compound to no avail.
My RD 350 LC will start better after running for a while whilst starting cold is a bother, I know it’s a bike with decades of technology advancements but it’s the most similar bike I have ran.
Thanks.
