Stu_B Posted September 19, 2009 Report Posted September 19, 2009 I had that on an old vw polo, it was to do with an earth to the engine or the carb can't quite remember, it was years ago.

Fishtailparka Posted September 19, 2009 Report Posted September 19, 2009 The strap to the engine itself need to be in good nick or it just earths through the throttle cable. That's what he meant.
drjekell Posted September 19, 2009 Author Report Posted September 19, 2009 what engine you running 2L pinto, just under 35,000 on the clock
caprinerd Posted September 19, 2009 Report Posted September 19, 2009 pinto has 2 earth straps going to the engine one from bulkhead to the rear inlet manifold stud bulk head is a screw make sure its tight as i had one that had a habit of getting loose all the time the other earth is, looking from the front, down on the right hand side near the dizzy and connects direct to the battery with another lead coming out from the battery to the strut top area of the inner wing check that the leads are in good condition and connected firm when you drive the car is there any hesitation in the engines performance apart from dieing on tick over
Peter-S Posted September 20, 2009 Report Posted September 20, 2009 Take out the two idle jets and give them a blow through. See if that helps as it sounds like there could be a bit of crud in there somewhere.

caprinerd Posted October 15, 2009 Report Posted October 15, 2009 the anti stall valve may have a split in it
drjekell Posted October 15, 2009 Author Report Posted October 15, 2009 the anti stall valve may have a split in it is there a site where I can get a diagram my haynes manual dosent have it in it also a setup of the carb in the car so I can see if the pipes are the rout way round Some pix would be very helpfull of what goes where
caprisun Posted October 15, 2009 Report Posted October 15, 2009 I had the exact same problem when I was running a pinto on this carb, just crap in the jets, take the top of the carb off, don't have to take the whole thing off I think from memory and whip the jets out one at a time so you don't mix up what goes where and blast straight throgh them with carb cleaner and hey presto its back up again. Did you have slight backfire when you let off when driving too? All sorted for me after cleaning them out.

drjekell Posted October 16, 2009 Author Report Posted October 16, 2009 A couple peole mentioned an earth....but if the car is earthing down the clutch cable, and the engine doesnt have its own earth, it still shouldnt die, as the engine would remain running via the alternator..... though I have had this problem on a transit, and at least this lead to the discovery that the charging system wasnt connected either i have tryed the earth cable as i have said before i have changed a lot and checked a lot to figure it out im guna strip the carb next week and blast out the jets and clean out the carb and if that dont work iv got a 1.6 i could put in for a while what do you mean by charging system and did the trany keep cutting ?
drjekell Posted October 26, 2009 Author Report Posted October 26, 2009 Hi just stripped down the carb it's all clean and clear but it's still cutting. Does anyone have any other ideas?
JP. Posted October 26, 2009 Report Posted October 26, 2009 Do you brake at the same time when your engine stalls???????????? If so, then your brake servo has died and causes your problem. Easy to check, remove the vacuum hose from the servo and plug it. Take it for a ride ( warning your brakes aint assisted now so you have to push the pedal harder to stop). If your stalling problems are gone now you know where your problem is...............

If your stalling problems are gone now you know where your problem is............... urm the engine will stall if I down the clutch whilst still moving without touching the breaks could it still be the servo ? I'll test it would it stall on the spot ? If it does then it can't be the servo can it.
