Hey folks I have a 74 Batavus Va and I'm having a hard time getting it started again . Had it going and running great and it has spark and headlight goes on when you peddle and squeeze clutch . took some lights off to clean things up and put new tires on and my son rode it down the street and he said he thought it ran out of gas . I think he put too much oil in gas when he fixed new batch , he put 5 plus ounces in a gallon. bike calls for 4% oil . Does anybody know the recommended amount of oil mix into 1 gallon ? Im also not sure what all the switches are on the bike . What is the key on the headlight for? and is there a kill switch on the bike that's keeping it from starting ? can't find anything about this bike any help would be appreciated ! thanks in advance
