Quote from: Underdog1 on September 01, 2018, 05:03:32 PMSo thankfully it seems it’s the washer on the oil tank drain bolt leaking rather than the oil hose, I’ll replace the washer at some point and see if it makes a difference.The seats currently with a local upholsterer getting sorted, have received a Morgan carbtune pro so I’ll hopefully have the carbs dialled in soon (unable to work on it this weekend though).The carbs are still dumping fuel seemingly randomly. I’ll put the bike away and switch the fuel off, tinker around with a few things and still no fuel dumped.. but when I come back into the garage the next day there will be fuel ok the floor. Sometimes it doesn’t happen for a few days and all of a sudden it justs dumps the fuel whilst sat doing nothing...They floats seem ok, if they were at incorrect heights or whatever surely it would just overflow straight away?I’ve had this recently on my 500. At first I thought I left the fuel tap on, but realised that the fibre washers in the petcock housing had failed and were leaking fuel through the tap down into the carbs. They would then overflow onto the garage floor. Quick test is to lift the fuel tank, and place it on a flat surface with a tray under the petcock. If the petcock is switched off but fuel starts gathering in the tray, there’s the source of the problem. Hope this helps. Sent from my iPhone using Tapatalk

Take the float bowl off and secure it level, fill with fuel and see if it drops then.You can get the internal brass "standpipe" tube cracked and it let's the fuel leak out even without breaching the float/fuel level.Check each in turn to find any errors.
If it is leaking with the tap turned off either the tap sealing disc is duff or you did not fit the proper washers under the heads of the retaing bolts
There is your problem as they should be thick fibre washers that you can not get genericaly. I have used 6mm "Dowty" style washers with some success. If a total seal does not happen fuel leaks down past the bolt threads and bypasses the tap flooding the float bowls
With hravity feed from tank and engine off float needles have to be perfect to stop flow. With screws sealed you should not get more leakink and floats will seal enough for normal running as long as you remember to turn off when stopping engine. I think this was one of the reasons vac taps became more common
