IT’S ALIVE!!
After much mucking about with the carb and cleaning the whole fuel system, Dave from Trabi UK managed to find me a NOS carb. I fitted this yesterday but the battery didn’t have enough grunt to fire up so I think I flooded the car. I left it overnight and put the battery on charge for a few hours this morning and it fired up almost immediately!
A pleasing cloud of 2 stroke smoke hung in the sun over my driveway for a while until the car warmed up. I just need to adjust the idle speed and its all systems go!
