Right so last weekend after replacing my trailing arm bushes, I decided to go out for a drive... I pulled up to some traffic lights and could hear a missfire, which got a bit worse and then ultimately it just cut out. I managed to start the engine again but it was rough and cut out again, fortunately I managed to just limp it around the corner from a busy junction. At first I thought it was just low fuel as the gauge doesn't really work too well (if at all)... so off I went with a jerry can to get more petrol. Fuelled up she fired up and seemed to run a little better, still not perfect, cutting out a couple more times in the next 5 mins or so, but after that ran well enough to get me 15 mins home. Up until this point it'd been running fine for maybe about 400+ miles of my ownership.
A bit later on it started up ok, and was idling for a few mins but again started missing and then cut out, and its been doing that pretty much every time since, the longest I've had it running this week is about 5 mins.
I quickly discounted any fuel flow issues as theres plenty flowing to the carb, so thought clear carb issue. First off I cleaned the idle jets and emulsion tubes (I think), whatever is accessible from the top. No real issue to be seen here but cleaned non the less. No improvement, so disconnected the choke and had the top off. Now there was a fair bit of dirt at the bottom of the float bowls, which is odd as its always had a filter in line, but I cleaned that out and stuck the lid back on for a test... No difference again, wouldn't idle. So then I tried the same again, cleaning it out again, had the jets out again and tried spraying some cleaner down the holes. Then I took the idle cut-off solenoid off to try and clean out better. Found the solenoid itself seemed to not be going in, I though I'd cracked it then, a faulty solenoid! But I put one from the old carb I got with the Landy on, put it all back together and again, no difference.
So now I'm at a bit of a loss, what do people make of this? what do I do next? The carb itself isn't that old, it was put on by the previous owner when he couldn't get the original running right, even with a rebuild kit. So now it seems like I'm in the same situation with this newer carb. I feel like this might be one of the reasons why you don't see that many 2.5 Petrol coilers these days... maybe life would be simpler with a TDI
