Brock-Lee Posted August 4, 2008 Share Posted August 4, 2008 yuh, but with these same plugs in it it was running perfectly, then suddenly it wasnt, I wanna figure out what caused the problem. Start a tech thread and I will do what I can to help To clarify, It was running perfectly and then overnight it ran like a bag of sweaty ass. I replaced a perished section of fuel hose and cleaned out the carb. Replaced the cap rotor condensor plugs and leads. Checked the timing and compression. Checked the points gap, had to file a "lump" off one of the contact pads with a points file and then reset the gap to factory settings between 18-25 thou. Car ran perfectly for about a week then it gradually got worse and worse till the point where it was undriveable again. Now I have to clean off the plugs(using a wire brush) before it will run and within 200m of driving it has returned to running like poo again. Help would be greatly appreciated Quote Link to comment Share on other sites More sharing options...
thegreatestben Posted August 4, 2008 Share Posted August 4, 2008 Replace the plugs with new ones? Found this helped my Hilux time a billion in terms of smoothness and longevity of plugs. Needed less Choke when cold so doesnt tend to foul up. Quote Link to comment Share on other sites More sharing options...
Unclejake Posted August 4, 2008 Share Posted August 4, 2008 Humph. You just had the dizzy out to check for play so I am going to assume you have re-checked the points gap. I am going to have to have a think Quote Link to comment Share on other sites More sharing options...
Unclejake Posted August 4, 2008 Share Posted August 4, 2008 Is she blowing black smoke out of the exhaust and does the engine oil smell like fuel? Quote Link to comment Share on other sites More sharing options...
Brock-Lee Posted August 4, 2008 Author Share Posted August 4, 2008 I just re checked points gap, is fine. Will throw a new set of plugs at it tomorrow and see what that does. when it was running good it didnt blow smoke but it does once the plugs start to foul up, ie at the moment Quote Link to comment Share on other sites More sharing options...

Testament Posted August 4, 2008 Share Posted August 4, 2008 what carb is it? weber? whats it off originally? you know how to set the idle etc.? Quote Link to comment Share on other sites More sharing options...
Brock-Lee Posted August 5, 2008 Author Share Posted August 5, 2008 tis the stock carb, yes I can set the idle and mixture Quote Link to comment Share on other sites More sharing options...
Testament Posted August 5, 2008 Share Posted August 5, 2008 also, screw the idle enrichment needle right out, and take it off the carb (just be careful not to lose the spring if it has one). I could never get the 124 to idle worth a damn and had some similar fouling issues when I had the original solex carb on it - i took the needle out and found it was bent! heck knows how it happened. Then I put a weber on it off one of my 2L motors and now it goes sweet/idles/starts easy enough. Quote Link to comment Share on other sites More sharing options...
dirty_leppa Posted August 5, 2008 Share Posted August 5, 2008 i got a spare carb if you want it dave. Quote Link to comment Share on other sites More sharing options...
Brock-Lee Posted August 5, 2008 Author Share Posted August 5, 2008 yea I have been meaning to get in touch with you bro. I will flick you a text to suss out borrowing that. You get yours running properly in the end? Quote Link to comment Share on other sites More sharing options...
KKtrips Posted August 5, 2008 Share Posted August 5, 2008 Does it foul the same plugs over and over - ie number 5 mainly and number 1 or 2 every so often?? I say recheck that the distributor shaft does not have play in it - it took me nearly a month of fucking around including lending my car to Unka Jake for a weekend while it was fucked to figure out that it was a worn distributor shaft problem on mine.. exactly the same symptom as you describe (well the local sparky and an oscilloscope figured it out - not me) Quote Link to comment Share on other sites More sharing options...
Brock-Lee Posted August 5, 2008 Author Share Posted August 5, 2008 it is an l20b which is a four cylinder. It fouls all the plugs over and over but mainly number 3. I am pretty sure it is a fueling issue, will borrow dylans carb and see if that sorts it out Quote Link to comment Share on other sites More sharing options...
