Boyfriend was doing some work on the camper at the weekend and he noticed that the idle stabilising unit was missing. Does he need to replace this? He has searched on the internet and some say you don't need it and some say you do. If he does need it, where would he get one from?
Also whilst he was tinkering, he noticed that the automatic choke on one of the carburettors is not working correctly. Can it be taken apart and fixed? If it can't, where could he get a replacement parts/whole thing from?
Excuse my heavily dictated message

would be grateful of any advice,
Thanks in advance,
Clare
