Hi, our old V35D had a problem when we aquired it, which we do not seem to be able to cure. It will start with difficulty on full choke, then runs smoothly at idle speed for about 10 seconds, then dies. It will not start again unless you leave it for about a minute - it then starts and goes through the same 10 second cycle again. Hit the throttle while it is idling for these ten seconds and it dies instantly. It has a brand new Impco J fitted which made no difference. Everything has been checked and cleaned over and over again - filter, pipes, solenoids, ignition etc. etc. Anybody experienced a similar thing? We are beginning to despair. Seems somehow to be gas starvation, but this is just a guess.
