Thread: Ex-Military 109 GS (202)

Took the pump off and re-fitted it (carefully) without a gasket.
Started OK but quickly died again, but this time carby full and pump had primed.

Eventually tracked the latest problem down to the bucket seal on the accelerator pump, it had split and a piece had fallen out (managed to fish it out of the carby).
I remember a lot of problems on my Series I which has a Holden carby, replaced about 3 of these seals then eventually tracked down a leather seal to fit onto the old brass pump shaft. No problems since.




Looks like I now need an accelerator pump seal.....

If you can get access to a lathe Colin, you could make two simple male and female formers and press leather seals; an old riggers glove would probably work well. Do it with the the leather wet - with a bit of ingenuity a lathe may not be needed,

Thanks Charlie, the owner is sending me a seal.

You need the original brass plunger for the leather seal, the plastic plunger is usually supplied with the Fuel Miser kits.

Steve couldn't find a seal so I tracked down a carby shop (getting a bit thin on the ground nowadays).
Picked up an accelerator pump piston in plastic and also a brass one with leather seal. I'll keep the brass one as a spare for my Series I and hopefully the plastic one will get the IIa running well enough to get onto a trailer.

Took the carby off and fitted the new accelerator piston/seal, put it back together, filled the carby with petrol and...... it wouldn't pump fuel when the throttle was opened. Took the lid off the carby and the piston was difficult to push down.
Back on the bench it turned out that the passageways from the bottom of the piston had dirt inside. Pulled out a small blanking plug & used compressed air to blow the dirt out and the accelerator pump is now working properly.

Hopefully when I fit it tomorrow everything works OK and it'll start & run.


Colin

Fitted the carby and it started OK but the motor was revving quite high.
Tracked down a couple of air leaks and also a lot of play in the throttle linkages. Couldn't find a spring so ended up with some bungee elastic and some wire to make a temporary spring to make sure the throttle closed fully.

Starts first time and is now ready to drive onto a trailer.

G'day Gromit,

How far away are you going to be parking the car trailer? It has been a lot of effort to get it starting and running.

Are you going to park the vehicle one end of your property set up an obstacle course and run up to the car trailer located near the exit to your place? It would make all your efforts more worthwhile and more fun too!

Kind Regards
Lionel

Lionel,

Steve is on 13 acres and has promised that one of my son's can learn to drive the IIa once we get it up there. I catch up with him 3-4 times per year.
He also has a big machinery shed and has promised that if I buy a Land Rover up his part of the World I can leave it there until the dust settles at home

It has been a bit of work getting it running but as always the challenge provides the reward.
