my 1300 driver is playing up again! heres the story, only when hot the car decides to what i can only describe as misfire on me as im driving (regardless of speed). all power seems to go, but can fight for the revs to keep it going...usually resulting in completely dying. So i pull over and check it out...but now ive got to the point where i know anything i do wont work so just leave it to settle. It does start again when you leave it for a few minutes, but when you rev it up from idle to about 4000rpm it jumps up the rev range, what seems to me like a misfire. then it will settle after a few mins of light reving and im ready to drive again....until shortly (not knowing when) it will do it again but the thing is i have changed the HT leads, plugs, dizzy cap, rotor arm, points and condenser, air filter, carb base gasket...the works, but im STILL getting this problem. Has anyone else had this type of fault happen to them? or can anyone lead me in the right direction. PLEASE PLEASE...all ideas welcome because im all out of them
standard air filter...ive made no mods to the engine... doesnt happen in the same place, just seems to be when the engine gets up to a gd working temp it starts to play up...then will be fine.....then play up...
sounds like carb freeze, have you got a warm airpipe leading up to the air filter? should be silver and corgated.
yes i do have one of those - if you mean the large one...about 2 inches in diameter? is there anything i can do about carb freezing? i guess thats the same as carb icing?
yeah, check the pipe is connected properly, it should be taking hot air from the sorst, it may also be worth you poping to your local motor factors and getting some carb cleaner.
right i'll go and check that pipe is on properly. as for the carb cleaning, shall i completely take off the carb and clean everything i can get to or???? should i dismantle the carb and have a look whilst cleaning?
Just spray some carb cleaner down the carb for now, whilst revving it a bit. see if it helps if not rebuild the carb or buy a rebuilt one.
Don't mean to hi-jack but my Driver is a bit of a bugger when started from cold and it doesn't want to idle until you've held it at a fast idle for a few mins (1800-1900rpm ) and it keeps wanting to die! You can get it to idle after a few mins of the above revs and it will then idle at around 850rpm (rally-esque tick over noise ) and when fully warmed up, this will be around 950rpm as specified by weber. This would presumably rule out it being the idle adjustment? Emissions are low and if you use a bit of choke to start it, it is too rich! I've looked for air leaks in the past but never found anywhere and I'm not that keen on spraying flammable liquids around the engine when it's hot! Should I just get it setup by some old skool fella's at my local carb place or does this sound similar to what other people have experienced in the past? Sorry kieranpatchton
that could just be that it needs a service, check you dizzy cap and rotor arm are in good contition, and that all of the connetions are tight, also check all pipes are connected properly.
no porblem mk1 driver, my warm air feed pipe is connected correctly. i where exactly do i spray the carb cleaner ? in the air intake part? wont this send my revs through the roof as the cleaner will be highly flammable? sorry if this seems dumb, its my first carb car...and theres a lot to learn about them
ive done some research on this problem now and im sure its carb icing can anybody help me with the warm feeds to the carb which prevents carb icing...im really not sure what im looking for here it is a solex carb on 1300 mk1 golf
check the flap in the air filter intake is working and the vacuum hoses on the bottom are connected to the carb and to the flap actuator thingy, sorry I cant remember where on the carb they connect.
ok ive now replaced the warm air flap and vacuum pipes! ive also taken the carb apart and cleaned with carb cleaner. ive cleaned out all the jets. also i replaced the ignition coil...... i am still getting the same problem though has anyone got anymore ideas...they would be greatly appreciated as im at the end of my tether[:^(] Edited by: kieranpatchton
do you mean setting the mixture on the carb up?? if so ive done that a couiple of times after fiddling about with it and cleaning it out and stuff
Check the flap for the warm air feed actually opens, there should be a vacuum pipe going to it, check there is vacuum supplied to the pipe while the engine is running. Is the warm air feed connected to a metal shroud around the exhaust manifold? It needs to be Check the inlet manifold pre-heater gets 12v when cold, check the inlet gets good coolant flow and I believe there is a heater on the carb, check this gets 12v. The other thing it could be is a dodgy fuel pump, my dads 1.3 started misfireing & cutting out, once we replaced the fuel pump all was well. Edit: Replace the fuel and air filters too if it hasn't been done recently Edited by: rubjonny
yeah ive replaced the air filter about 2months ago and the inline fuel filter only a week ago....both in desperation of trying to sort this problem out when it happened to me last night i sat there with it idling...and i got a sort of 'popping' sound every now and again coupled with a fluctuation of engine revs.... does this extra info spark any fresh ideas?
