Hi Guys.. I really appreciate all the input.. i am making progress.
yesterday I did as Lynall instructed.. (only saw his post after unfortunately)
I remover the throttle linkage and got access to the blank cover and removed with an alan key.
When I got the the blank cover out I fond it had a thick layer of rust on the back of it. Using the Allan key I pushed through the hole. I was being very ginger as I was not sure what I was doing but after a bit and what I feel was a firm push the pin popped out .
I worked the pin and use WD and I feel it is pretty free. and using a screwdriver in the Throttle linkage pivot, the pin pops out when you rotate the throttle by hand. The pin only pops out at the last bit of the stroke... nearly at full throttle.
However, I found that when the throttle linkage was reassembled the pin did not pop out even when at full throttle? I tested this a couple of times. Looks to me that the throttle is not opening to the Max ? and so no pin pops out.
Never the less I reassembled it all and took it for a spin. Nothing has changed :-( still this huge flat spot where the engine won't pick up until the foot is to the floor and then max 50/ 55mph. The only thing now is that while the tick over is fine, when I rev the engine it will die unless I press the accelerator as the reves drop. ( could be I put the throttle linkage back one notch off? ) but tick over is ok so I am not sure if I disturbed anything.
A few questions.
1. how and why would you adjust the stops for the throttle linkage? (my adjustment screw is rusted in place.
2. How much should the throttle rotate... mine is about 30 degrees from idle to full throttle (linkage in place) but it will rotate 45 without the linkage in the way. ?
3. Would you have expected an injection pump rebuild to include the refurbishment of this "compensator " and throttle part ?
Where to next ?
Heres what I found.
After working the pin and lots of wd
but with the throttle assembly... no pin?
