Hello Leuts, want to comment on the topic Starter nozzle, could find little in the net. I have the following history at the moment: Had on the vehicle a replica carburetor there was now the seat broken. I replaced it with a Dellorto PHVA 12 HP was with E-Choke and NEW The vehicle is a Malaguti F12 BJ 1996 LC 50 with Minarelli engine without cat. The nozzle are original HD 74 ND 38 Starter nozzle 48 Needle notch 2 position from above and GA 211. The vehicle jumps now cold level I tried it with a manual choke which helped, the result was it immediately started. The E-Choke has a distance at constant +15C of 10.56mm (measured without tip and without tension) which should actually be sufficient. Now the good question is if you could get here again some more fuel for larger starter nozzle and so the thing can work counter.
