Lister FR3 problem
Paul Hunter
started it and it ran away with itself going on to max rev with the throttle
and stop lever being useless - I eventually stopped it by turning off the
fuel. Started it again - same thing happened, again turned off the fuel
(altough I now understand that I should have blocked air inlet.)
Now it won't start at all although there is fuel coming through but the rack
seems to be stuck The level in the oil tank is only margianally up. The
governor seems to be OK.
Any suggestions anyone?
Thanks in anticipation,
Paul Hunter

Get the fuel pump overhauled - it may have had water in it at some
stage.

The FR series use individual fuel pumps for each cylinder, with a connecting
linkage between them.
The pumps must be pumping fuel or the engine wouldn't run at all, so a stuck
element is out. Looking at the manual, there are a couple of different forms of
throttle control, but the most likely problem would be the governor or the
linkage, as this goes to full throttle as soon as you stop the engine, and if
anything seizes in this position it will not release that easily, although I
would have thought that the governor weights would produce a hefty pull at max
rpm.
If the governor linkage breaks between the governor and the pumps, then the
return spring will hold the throttles open at full rpm. It is a steel rod,
linked to the pump nearest the governor. The other end is inside the governor
housing itself.
The parts list shows a hollow tubular connecting rod while the main pic shows a
solid rod. The tubular rod is in two pieces with a spring inside. If that tube
becomes detached it will give you full rpm with no control by stop lever or
throttle.
