Well after fooling around a bit with the pump I found that I had put the roller saddles in back to front.
For those that don't know, if they are in the wrong wrong way it will only pump about half the amount of fuel.
These rollers run on the inside of a cam for pumping the fuel.
I found the pump easy to overhaul
myself in the garage. I'm an auto electician by trade
. I just bought a basic repair kit from Peter Slater in the UK their website is www.pslaterfie.co.uk
. I think it cost me about $30 AUS and was well worth it.
So, for those who have any basic mechanical knowledge do the pump yourself. It will probably only take about 3-4 hours to do it.
If the engine used to run ok just make sure that you don't adjust the plate screws that deterimes how much fuel is pumped out by the pump.
This plate will determine how far the rollers move in the outward position.
I can't see the value in paying someone $500 to whatever it costs for something that's so easy to do yourself.
Just make sure the saddles that hold the roller bearings are in the right way to begin with.
I just washed all the parts
in petrol in a small container and reassembled it with new "o" rings, seals
, rotor viens and gaskets.
