mk2escort Posted September 25, 2009 Share Posted September 25, 2009 Im new to this and dont no jack about cars so dont cut me down please. So just got my first car a 1980 4door mk2 escort L and I'v noticed that when I turn it off it keeps spluttering and shakeing around abit for a while (long enough for me to get out of the car and lock it!!) I have been running it on 91 and will put 95 or 98 in it next time but is there anything else i can do to stop this? Quote Link to comment Share on other sites More sharing options...
ESKIN8R Posted September 25, 2009 Share Posted September 25, 2009 Welcome to the site Perhaps the idle is set too high, does it have a rev counter? You could slightly lower it and see if it improves. There will be a screw that acts as the stopper for the throttleshaft Single throat carb I pressume? Quote Link to comment Share on other sites More sharing options...
mk2escort Posted September 25, 2009 Author Share Posted September 25, 2009 ummm it dosnt have a rev counter and i duno what all that other stuff means i really am machanically nil ae (Its a stock standard 1300 escort L if that helps) Quote Link to comment Share on other sites More sharing options...
ESKIN8R Posted September 25, 2009 Share Posted September 25, 2009 If you let it continue to run on like that its guna do some damage. One thing you can do to stop it is to put it in top gear with the handbrake on and stall the engine out. But really you needa solve the issue causing the run on...

sholdowa Posted September 25, 2009 Share Posted September 25, 2009 Wap $20 of 98 in it and thrape the bollocks off it. At the end of that, you'll have cleared any extra carbon out of it, and you'll be sure the engine's solid. Or not (: Quote Link to comment Share on other sites More sharing options...
steve Posted September 25, 2009 Share Posted September 25, 2009 Your mixture is probably running to rich you need to adjust and make slightly leaner. What sort of carb is it? If you rev the car up before you shut it off does it run on? (Don't go nuts just blip the throttle and as the revs drop away kill the ignition) Quote Link to comment Share on other sites More sharing options...
FuzzayD Posted September 25, 2009 Share Posted September 25, 2009 If it doesn't stop then maybe its over heating quite a bit and self igniting mix off hot internals. Topped up the water lately? Quote Link to comment Share on other sites More sharing options...
My name is Russell Posted September 25, 2009 Share Posted September 25, 2009 Does it backfire when you engine break once the engine is hot My 1300 used to over run when she got hot from the valves pitting and getting fuel in them etc as above. Sometimes it would over run for like 10 seconds in summer, was roffles as Solution ... put a pinto in it Quote Link to comment Share on other sites More sharing options...
mutiny Posted September 26, 2009 Share Posted September 26, 2009 sounds like the timings out to me Quote Link to comment Share on other sites More sharing options...
KKtrips Posted September 26, 2009 Share Posted September 26, 2009 overrun can be caused by multiple things : high idle - turn it down, wind the idle screw on the throttle linkage about quarter of a turn anti clockwise : too rich - lean it out, wind the idle mixture screw at the base of the carb clockwise half a turn : too far advanced - retard the timing, loosen the distributor and turn the distributor about 2 mm the direction that the rotor turns : carbon buildup inside the combustion chamber glowing - decoke it, take the vacuum hose off the distributor (it goes from the carburettor to the distributor) and put itin a 600ml bottle of water and rev the engine to around 4000rpm and let the water be sucked into the engine : too much compression - can't do anything and if the motor is stock it won't be this failing the ability to understand these, you will need to pay/bribe a knowledgable person to perform said tasks there are a combo of things that it could be so on second thought it would be better to let someone look at it Quote Link to comment Share on other sites More sharing options...
mk2escort Posted September 26, 2009 Author Share Posted September 26, 2009 yea im going to try and run it on 98 if that dosnt help will have to get someone in the know to look at it thanks for the help. Quote Link to comment Share on other sites More sharing options...
tortron Posted September 26, 2009 Share Posted September 26, 2009 had a problem with the minor running on and being a pig till high revs The mechanical advance weights had gunked up and frozen in a well advanced position - once cleaned it was fine. carbon/decoking probably isnt the problem - slam a couple of cups of meths in the fuel tank next time you fill up and itl get sorted Quote Link to comment Share on other sites More sharing options...
SHGWAG Posted September 27, 2009 Share Posted September 27, 2009 Had this problem in my old mk2, gave it new leads, new dizzy cap, put some 98 in it and took it for a thrash. Fixed the problem. Quote Link to comment Share on other sites More sharing options...
Chrome_GT Posted September 28, 2009 Share Posted September 28, 2009 Try 98 or 96 before doing anything. I find my Capri runs like shit with 91 Octane but problems all go away with high octane. My Thoughts Try Higher octane - if this works stick with it or adjust timing to suit lower octane. Running too lean also causes run on doesn't it as a lean burn is hotter. Retarded timing gives run on as late combustion is more likely to heat up the carbon deposits on or near your exhaust valve. Don't mess with the mixture until you've done timing as it is unlikely your mixture is suddenly incorrect. Quote Link to comment Share on other sites More sharing options...
