Carburetor diagnostic

I managed to get the scooter running by pouring some petrol directly into the carb only.

So I suspect petrol from the tank was not being drawn into the bowl..

Bit mucky in there...quick carb clean and wooden toothpick.

The main fuel tube was blocked..so using some welding wire and carb cleaner finally allowed fuel through.

With the carb back on the engine I managed to get fuel drawn into the bowl from a makeshift tank..The vacuum drawn fuel meant all was well...but the engine was not smooth ,often idle falling ,rising and stalling. It seemed to prefer running with full choke..so base settings will be researched for the carb once I have identified it..

The carb has the following ID on it

M72 PDOC

I found this on the net for PD carbs - but i suspect mine was built by Bajaj under license??

PD carb

The  main jet is #108

The slow jet is #42
