Hello,
I have a hyster H3.00XMX.
It idles a little lumpy, and the governor doesn't seem to be operating correctly.
it has a gas engine in it. It runs okay but a lot of the vacuum pipes have been replaced and the map sensor is there but not connected the the manifold. If anyone has a service manual, or some details on the routing of vacuum hoses, I would be very grateful.....

Many thanks in advance
