I've posted before regarding my doing up an old Allen Scythe.

My problem now appears to be the carb.
It is an Amal 519 which I discovered was missing the float.
I have bought and replaced the float, needle valve and gasket.
Now it doesn't seem to draw fuel into the engine. All jets are clear and oddly enough, all be it badly, the engine will run if I remove the float!!
Also if I pour a small amount of fuel into the top of the engine and replace the plug it will run for a few seconds until that fuel is burnt.
Has anyone any constructive views on this!!

Martin,
This sounds as though there is insufficient fuel in the fuel bowl with the float fitted.  I presume the replacement float and needle are corret but may be closing off the fuel supply to early.  Not familiar with the set up but can you alter tab on float to close later.

like Neil I'm not familiar with the set-up but years ago I had a similar problem with an Amal carb. It had a long fuel needle through the float, the bottom of the needle sat in a hole in an upstand in the bottom of the float chamber, rubbish in the hole prevented the needle from going down far enough to admit fuel, if your carb is similar it's worth checking.
