grey not going

EKjimmy · Post by **EKjimmy** » Mon Nov 02, 2009 10:33 am

car idled okay this morning, as soon as i drove ti down the street started to run rough and sort of splutter a bit, then as soon as i went to take off up a very slight hill the car cut out.
started again, ran very rough. when choke is pulled out the engine stops.
when running, exhaust seems sooty.
fuel pump had all sorts of shit in it last night so i cleaned the bowl and drained the carby, fuel is getting through the jets (tested by holding my hand over throat of carby and opening throttle-engine off)
cleaned plugs last night as they were fouled.
any ideas?
Thanks, Jimmy

I'd say you still have shitty fuel somewhere in the system.

yeah, i cleaned the fuel pump and HOLY HELL! but yeah tried to clean it all out, drained carby. i think maybe one of the jets is blocked or something? possibly?
just took it off then except i dont have one of those tools for taking the jets out

anything else that can be used?
the bloody car is at the end of the street so i have to keep walking back and forth, thats why i took the carby off.
Cheers, Jimmy

If you have got crap into the fuel bowl then it will have made its way into the carby as well.Even with a fuel filter the micro sized dust particles still get through into the carby and eventually block it up .

You don't necessarily need to remove the jets to unblock any blocked jets, just need access to an air compressor and an air blower to blow out the shit that is blocking it up.

The strombergs are very easy to clean out as you don't have to remove many parts to be able to clean it out.

If there is crap in the fuel system then it is coming from the accumulated crap in fuel tank and your best advice is to eventually remove the tank and clean and dry it out properly or it will eventually happen again and leave you on the side of the road once more.

Also good advice is to install a fuel filter between the pump and the end of the steel fuel line from the tank.

Also don't forget to blow out the idle passage in the carby base as this affects the cars ability to idle properly.

Count the number of turns you have to turn to undo the screw and don't lose the small spring on the screw as it stops the screw from moving due to engine vibration.

After blowing out the idle passage reinstall the screw using the same number of turns you undid it.

You will have to re adjust the idle screw mixture but the above is a way of getting it to a "round about right" position.

this happens even more when just filled with fuel as the new fuel entering the tank stirrs up the accumuled crap on the bottom of the tank.

given the carby and pump a good blow out, so i'll just have to put it back together-although i might leave it till wednesday and take out the whole fuel line and clear that just to be sure i've done it all right.

Remember the fix may only be temporary Jimmy as the accumulated crap in the tank is the end cause of the shit making its way into the other parts of the fuel system.

I'd be taking the extra trouble of tank removal and clean.I know its a pain in the arse job but its a pain in the arse having an unreliable and intermittamt running fuel system because of a dirty tank.

Yes, it will.So does general driving as the fuel sloshes about in the tank.Eventually it builds to a point that it slowly makes its way along the fuel system to a point where it starts to affect performance.

whole fuel system has been flushed out and i swapped carbys between the cars-both carbys are fine so i can rule out fuel system.
still tries to turn over but wont actually start-checked spark, im not sure how big the spark should be but it seemed sufficient.
anything else i should be trying?

just charging battery at the moment as it's gone dead from the repeated failures at starting lol.
distributor timing has not been touched but i guess i should try that IF it starts in the first place.
at the moment im convinced it's something electrical.
distributor is working, but maybe the coil isn't giving enough power for a proper spark?

thanks again for stretching your minds fellas

If your battery is low on charge and sluggish/struggling just to turn the engine then there will be little power left to give a good spark at the coil so a good battery and/or a good charge is essential.

Do you have spark at the plugs as spark at the coil lead doesn't necessarily mean spark at the plugs.

Try and get it going as is but if it won't you will then have to go through a systematic elimination process like checking ignition timing etc.

Just a thought along one of the grey motor weaknessess, does the distributor shaft turn when you are winding over the motor.If not, could be a failed fibre cam gear and you'll be wasting your time checking anything else.

yeah the shaft turns, and yes spark is getting to the plugs-i'll check coil anyway just in case so i can eliminate that or fix it. i'll get there eventually

Thanks mate, Jimmy

okayyy...
fuel lines are clear
fuel pump is clean and filling up with clean fuel no worries
carby is fine, jets clear etc
dizzy points are okay, shaft rotates
plugs getting good spark
vacuum lines to carby are secure.
car cranks, but won't start.
im absolutely stumped. i swear these cars hate me

Throw me your phone number via PM if you want and I'll see if I can help you out over the phone, far quicker/easier than fixing the prob by typing.

Won't be able to ring until tomorrow night though.

my car was doin that the other week, needed new condenser and new points in the dizzy.

is there a kink in the fuel line maybe? if u have a hose that could be it.
