BAR118 Posted July 18, 2011 Share Posted July 18, 2011 Last week my mini decided it only wanted to run on 2 cylinders, so i spent hours messing round with my ignition and timing before noticing that my reasonably new fuel filter was basicly solid black and the fuel that was going through it was a dark brown. I took apart the float chamber and there was literally half an inch of sludge in the chamber. (Keep in mind that I have only had the car running for 1000kms or so since full over haul). So I took out the fuel tank, fuel lines, carb and manifold out and started drowning things in meths. Replaced filter, and fuel lines and gave the carb and tank a thorough clean. Put it all back together last night and now I have copious amounts of fuel in my carb/manifold. Anyone got any idea why I'm getting all this fuel building up?

Unclejake Posted July 18, 2011 Share Posted July 18, 2011 Is it possible you have adjusted your float level incorrectly (I can't remember if an SU even has a float bowl)? If so then I would look at float level or the float valve. The manifold is below the carb so if the carb is too full then neat fuel could drain into the manifold Quote Link to comment Share on other sites More sharing options...
mjrstar Posted July 18, 2011 Share Posted July 18, 2011 will probably be shit under the float valve seat, so will not seal when the float is right up.. I have had this on a few occasions.. just whip out the pin for the float and have a bit of a clean-up in there.. (part 19) Quote Link to comment Share on other sites More sharing options...
BAR118 Posted July 19, 2011 Author Share Posted July 19, 2011 Just took apart float valve, was nothing in there but gave it a wash and a blowout with the compressor. I also went and leaned the mix right off and went to go crank the engine but dead battery, so waiting for batt to charge. Quote Link to comment Share on other sites More sharing options...
BAR118 Posted July 19, 2011 Author Share Posted July 19, 2011 Ok so Battery is charged, still no starting and I still have fuel all through the carb. I'm tossing up weather to change the needle over, but it was running perfectly before with the needle that I put in there. What do you guys reckon?

Beaver Posted July 19, 2011 Share Posted July 19, 2011 is the mixture set right? I put new carbs on the triumph in the weekend and they were pissing pertrol everywhere, set the mixtures correctly and fixed it. Quote Link to comment Share on other sites More sharing options...
BAR118 Posted July 19, 2011 Author Share Posted July 19, 2011 Mixture is sitting where it was when the car was running last week, I'll go lean it right off and see if I'm still getting the same thing. Quote Link to comment Share on other sites More sharing options...
BAR118 Posted July 19, 2011 Author Share Posted July 19, 2011 Dryed the carb, leaned it off and cranked it. There was less fuel sitting in the carb but it still doesn't want to fire properly (at all). Yanked out the spark plugs, theyre soaked in fuel, so cleaned them and I've got heapsa spark. Went to start cranking again and my battery's dead again so once again waiting for charger... FML Quote Link to comment Share on other sites More sharing options...
BAR118 Posted July 21, 2011 Author Share Posted July 21, 2011 She's still not starting, do you reckon stale fuel would be causing it to oerfuel like this? I've changed needles, changed float valve, this is doing my head in, the bastard just does not want to run! Quote Link to comment Share on other sites More sharing options...
goindf Posted July 31, 2011 Share Posted July 31, 2011 Sounds like it could even be electrical especially if the spark plugs are getting wet with fuel, what are the points like? have you tried new leads? The spark plugs may not be to good either if you had dirty fuel go through. Let us know how you get on Quote Link to comment Share on other sites More sharing options...

goindf Posted July 31, 2011 Share Posted July 31, 2011 Could even be timing possibly, which 2 cylinders is it not firing on? Running Single SU or Twin? Quote Link to comment Share on other sites More sharing options...

It's actually not starting at all now after I replaced fuel lines and cleaned tank etc. I'm running single Hs4. Quote Link to comment Share on other sites More sharing options...

felixx Posted August 2, 2011 Share Posted August 2, 2011 I had similar issues with my anglia. Bottom line was she was not generating enuff oomph in her spark (I had a ballasted ignition - didnt know it and was running a 2nd ballast resistor with the coil I had.) I removed 1 ballast resistor changed the plugs,and all was rosey. (Very few anglias have a ballasted ignition so I was caught out there. Is your coil OK? How are your points? I put in a new condensor as it was only $9 at repco, at least if you have her running before the electronic ignition goes in you will happy.
