I had Golden Arrow do some work on my outboard as i could not start it they cleand the carb and told me it was running fine . When i tried it i still could not get it to Idel. So they took it back to the work shop. They called me and told me i needed a small part for the fuel intake coossting 25 quid so i said ok fit it . 4 weeks later its back on my Boat working great . Then i get the invoice foor 469 quid .What would you do NOW
