hey guys, being this my first real car, i having trouble learning to fix things hahahaha. anyway, not sure if all cylinders are firing, and the engine cuts out when i stop or sit in neutral. wondering if anybody with good experiences with a 4ac or anybody knowledgeable could come and have a listen/look. can supply some beers and a bbq or something, jsut would be great as being a UNI student, money is slow.

regards in advance, Khai

Just turn up the idle screw alot... what revs does it sit on before it dies?

ive slammed all the screws, it revs high around 1500+, had it idling find on 900, then i reversed out fine but as soon as i drove and got to my first stop sign.........cut out.

like ill sit in neutral and get it so its out of the flat spot and hold the accelerator on 2k rpm, it will rather quickly just go 1800..2000.1800.2000.1800..2000

Could be losing spark, or fuel

Checked Sparkplugs?
Checked Ignition leads? Distributor cap??? Coil ?
Checked Fuel filter? Fuel Pump???

no. i think one cylinder is miss firing. im really new to all this and no nothing, trying to learn from forum asnwers from people who talk like i know what they are saying half the time. hahahahaha. just put new ngk plugs, nothing. might try leads but they r newish. when i look at a jet inside the carby throat, i see it kinda of plurting fuel when in those flat spots.

does it have an automatic choke, or a manual choke (cable that goes into the car with a knob?)

if i hold accelerator in the flat spot, it will stall.

Time for you to find a mechanic.

one word of advise, if you have know idea what your doing, take it to a mechanic.
i am a mechanic and i cant tell you how many countless people bring there cars in because "they had a go at fixing it" and made it worse.
and it can really come down to alot of things, ie plugs, leads, carby tune, timing etc

nundahhhh. =] i think maybe something to do with fuel pump. i mean firstly it literally would stall in neutral or changing gears. but tuned the idle down to around 500-600. this stopped the cutting out, after around 5 mins it just began getting flat spots, and now like sometimes if i don't pump the accelerator when in a flat spot it'll just stall. hadn't ran the car for around 4 months, could it be crap in the fuel tank maybe getting into fuel pump? but then again, it happens on a pretty accurate time when driving, as in its always at the same time (when taking off, but also mildly when driving u feel slight jerks.

if you havnt ran the car in ages, it sounds like its fueled up, try this - drive the car around HARD (high revs) for a day or so to cleanse the carby out, then see how it goes after that
