Hi, I have my father’s old Victa Mustang Series 70, 2 Stroke, Mark 4 lawnmower that has served us well however it has developed a fuel leak from the black primer bulb assembly. (See photo attached) I have tried to get a replacement primer bulb however there appears that the parts are no longer available due to the age of the lawnmower. Apparently my Victa Mustang has an early version Mark 4 engine with a LM carb and the configuration of the carb and the primer bulb are different to the later versions! I am now wondering if anyone can please provide any advice on whether I can source a similar primer bulb or a solution to fix my fuel leak? Cheers, Lecky23
