The problems you and your old man have had with this 'mechanic' beggars belief! If that's not the best reason to rtfm, and do it yourself, I don't know what is! You can do almost anything with a good manual, and any extra help you might need, is right here. On this forum! Good mechanics, who really know their stuff are few and far between. That's why they're expensive! Having said that, there's a virtual gold mine of information to be had on OSS! When I see the standards, levels of skill, attention to detail and methodical workmanship, to say nothing about innovative ideas, on members projects/builds, I feel humbled! Long may it continue!!!
