I am in Australia and own a 1978 Suzuki Stockman LJ80 800cc 4 x4 Utility with a F8A motor. I have replaced the cylinder head with a second hand one and now can not get the Distributor on. I have the specifications on how to fit the distributor, but it still does not fit. Does anyone have any ideas on what the problem could be? Is there two types of distributor or cam shaft? Any ideas appreciated.
