2.5 N/A Hunting

CharlesY - ta for your advice on my leaky injection pump a few weeks back... But, explain this please! I bought a replacement pump, it arrived on the day that I had to drive 130 miles to chester and back. After this drive, the pump hasn't leaked a drop, and this was a week or two and a few hundred miles ago... Wha..? Is it likely to start again? Shall i keep my now spare injection pump, or do I sell it on again?


Murphy's Law 4456(a) says as long as you have the replacement pump, the old one won't leak.
Murphy's Law 4456(b) says the day after you part with the new pump the old one will start leaking big time.

Your decision!

Also, closer to this thread, when i bought my 90 the 'no throttle' adjuster bolt was wound right back in so that it didn't even touch the throttle linkage. In my ignorance i 'adjusted' this to make it touch the linkage and hold it open a tiny fraction. Should I put it back how i found it? It did seem to tickover extremely low when it was there, but should I put this back and adjust what I now know to be the slow running thing? Or should I just leave it as it is?

It is a pity it was touched at all, but the main throttle lever MUST rest against the STOP screw, but must NOT be used to control tickover. You were right to put it back.

I suggest ..... start the engine, and let it idle. Try VERY SLIGHTLY opening a gap between the tickover lever and the pipe it leans on, and the slightest gap should raise the tickover speed.

Now with the engine still running, back off the MAIN throttle lever stop screw until you can clearly see a little gap. The engine speed should not slow down doing this. Screw the stop screw in a tad until it touches the throttle lever, then no more than a quarter turn more, and lock it there.

DON'T do the adjuster screw other end of the main lever as that limits the upper engine speed, and if you raise that by any significant amount the engine may come to very serious harm.

All tick-over speed adjustments should be done on the little lever that leans on the fuel inlet fittings.
