2.1 ticking over way too fast!!

Post by wasserleaker »

Does anyone have any advice on this problem, can't adjust the idle speed on my 2.1 DJ digijet inj. engine to less than 2000rpm! the air bleed screw in the throttle housing is completely closed, timing is set properly according to the manual, strangely it will tick over lovely at 750rpm when switched over onto L.P.G. which makes me wonder if the idle speed stabilisation valve is working right, as it is switched off when running on L.P.G. It buzzes when running on petrol so it must be working, but maybe its supplying too much air [ if you block the rubber pipe by squeezing it the tickover speed drops to roughly the right r.p.m's] also the revs at idle go up and down at a regular rate which doesn't happen on gas, the rest of the engine is in very good condition as it was just rebuilt recently, anyone had similar problems and managed to cure it ? ? any help would be brilliant.

Try bypassing the Idle stab valve electronic box. (you should do this to set the idle)
