i would start with cleaning the carb internals especially the choke and pilot jets clean them and make sure all holes are clear then make sure the choke is closing off fully

Did you have any joy with your carb, definitely sounds like a blocked jet to me or the choke is sized, the way to tell is if it starts and runs once it's warm it's the choke, if it will not run properly when warm it's jets , remove your carb and strip, clean and clean out jets with a piece of copper wire and blow them out.. I once fitted a brand new carb and the engine would not run properly and when I looked inside the main jet was blocked by a small piece of aluminium from the machining during manufacture. I got there in the end and that was a brand new jetex carb..

Welcome aboard - try your question in the tech section though

Carb = SHORT FOR CARBURETTOR. THIS IS THE COMPONENT ON AN ENGINE THAT MIXES THE PETROL WITH AIR BEFORE INDUCTION AT A PREFFERED RATIO OF 15:1 BY WEIGHT. IN AMERICA THEY ARE OFTEN REFERRED TO AS MIXERS.
