Went out this morning and started checking for the lack of tachometer and hour meter. I knew it had worked and nothing indicated a major problem. I know electrical as have taught automechanics and work on computers for a living. located the crankshaft sensor and started checking wiring. Looked behind the module and could find nothing wrong. earlier I had looked at the white connector coming from the crank sensor and thought it was OK. (wrong) can't blame China for this one. assembly crew had not latch the wires in the connector. bent the taps slipped them in and got a nice click. Cranked up the tractor and away the tach went. I think I should have had chip put this thing together. finding lots of loose things. I am happy with the tractor. I never cease to smile when I look at it. Want to put it to work. Have five hours on it now. needs more breakin. Thanks for all the advice on the fuel tank. I was going to use muratic acid, but think I will try to just clean the loose rust and keep the tank full. I need to get filters for fuel, oil and hydro oil. Has anyone found metal in the transmission or front drive? I also would like advice on viscosity of oils. Book seems to recommend #30 or aw32. AW 32 is number 10 SAE. I am confused about what to use. I do know that whats in there seems to be #30 SAE. I read some treads, but still confused. I find this site to be of great help.
