AAZ fast tickover

Post by **vantheman** » 06 Oct 2006, 10:36

This is an outstanding problem on my AAZ coversion. I recon the engine is ticking over at 1000 - 1500 revs (no rev counter)

Am doing more local short journeys now and problem is more apparent.

The throttle actuating lever is at the limit of travel with the stop slackened off

What other adjustment options are there?

maybe the throttle linkage/arm has been fitted incorrectly and the thottle is being held open , remove the arm viva the 8/10 mm nut and move it round a couple of splines, mark every thing befor you start so if it does work you can return every thing to wre you started from

There are two other adjustmenst as well if that doesn't work, I'll dig out the link..

This ofetn happens when the main fuellling screw has been screwed in, to increase fuelling.

also check the cold start on the back of the pump (nearest the engine block) is returning to the off position

That only advances the pump timing by a few degrees and doesn't actually raise the engine speed.

Sounds like someone has been messing with the fuel screw to me.

Thanks for the advice, I have managed to reduce tickover marginally.

As economy is good ( 37mpg overall) I am reluctant to attempt trial and error adjustment. In any event I am not sure which is the actual screw.

Many Thanks
