update ,,
Got spedo corrected and i seem to be going 2mph faster than it says ... prob due to larger tires than stock

i was sometimes having a bad vibration at 1500-1850 rpm ..
i first thought maybe the flywheel was out of ballance ..
but someone sugested injectors ..

tested all ,
2 were almost 2000psi .. and one was spraying off to a angle .

tested them and not have them all set at +- 1650 or so .
seems to be running a lot better


had to modify the gas filler to take a larger diesel hose .. and tank had pump removed and made a hard line that went to the bottom ..
