I had the exact same problem with my tb42 petrol gas
All it was was the fuel lock had packed up so I replaced it & bingo
Follow your fuel line from your carbi back & you will find the fuel lock Im talking about mine is in front of my brake mastercylinder, Bypass it & see if she starts
I did excatly that & then swaped a old XR600 which only cost 2gs for a 8G patrol
