Tanks BM, no visible contacts so would continuity between pins when hot suggest contacts closed.
Next problem, Auxiliary Air Valve, came back after 3 months supposedly sorted. Virtually no voltage to the said.
Ran a new cable from the positive at the fuel pump relay and sorted that.
While ago that seemed fine 1600 revs dropping to 960 after a few minutes..
Started behaving erratically. Stuck in a spare, now starting at 960 and staying there but running fine.
Saw the method of squashing hoses, bit daft as they are hard plastic.
So wondering if the earth wire to it is goosed or can I just put 12v direct to see if any of the 3AAV's
I have function correctly?
