You can get one for 15 bucks @ Amazon that will work you don't need anything fancy.I don't know what route you are taking, I am thinking it's 150 miles on 40 from you to me if you don't get it figured out stop by on the way and I'll help you out

I bought mine at harbor freight. Cheap and works well. Stick the tape on the crank pulley... And shoot the gun at it

OK took it for a test drive and had no power to climb even a slight incline. stopped and meet a guy that does custom land racers land speed he had a contact tach. we took and ran the rack the whole tune up by the book. my tach shows 4.75 for idle and the other shows 550.  for no load mine shows 17 and the contact tach shows 21.50. but what really got fixed is everything in the governor and the rail was all bound up so now the stop lever and the throttle lever works easy and smooth.

Will set the Jakes and see if we can get them working. He also made me a wedge tool :) Then take her for a test drive.

I mover the bus to his place and he is a great guy he went and pulled the trailer over here :) He has a complete machine shop at his house. Will ask him if he would be will to help out bus nuts in need when they are in need around here :)

Yep it usually just takes a little paint thinner for cleaning and fresh oil and they are back to life,if it is running good I wouldn't bother with the wedge and the air gap setting JMW

OK is there a easy way to get a tach working in the front for driving.

RobSedona

on the test drive power was better but the rpms went down slow which made it hard to down shift Jake breaks where slow to come on.

Thanks Rob

   How about a weak fuel pump. Do you get any smoke when it is under load on a grade? Are you getting full throttle at engine with pedal floored? Manual or air throttle?
