The man is wise beyond his years. Also wise beyond mine, as I would have to chase down a thread on each one of these things, one item at a time. Actually, I'd probably try to get my old man out for a week to help me get it right, and then plan to run it hard for a couple days buying food and drinks along the way as a thankyou. I have however known a guy who had major work done to find out the "engine" problems" were problems getting the fuel to the engine. Start with the cheap and likely fixes prior to spending big on large ticket items that may not help.
I spent most of my money on booze, broads and boats. The rest I wasted. - Elmore Leonard
