Somewhat frustrating

[pyoor_excuse]

Normally I can work out why a car isn't running right. I may not be able to fix it, but I can suss out where the problems lie. But not this time.

She has a spark, she has fuel and she has air. She clearly has some compression, and yet she will not run. One cylinder is working just fine and dandy, the other one just refuses to do anything. I've tweaked the timing and adjusted the mixture anyhow, but she's completely sickly, will only really rev in neutral and let's just say I'm not particularly looking forward to the journey to the garage on Monday.

I'd probably have been better off spending my time getting a new brake-light-switch for Charlie, so she can go to an MOT. But I don't really have time for an MOT on Monday anyhow.

I hate the really odd ones.. Is the spark occurring in the right place? Is it arcing past the plug, or even in the dizzy cap? are the leads the right way round on the dizzy? (hey, I've done it in the past.)Are the valves doing their thing, at the rignt time and in the right way? Is the fuel actually getting into the cylinder?

I strongly suspect you've tried all that. But there might be something there that twigs the 'Bloody hell.. Of course' moment. Good luck!

I haven't checked the valves - because the problem's persisted beyond the replacement of the head. I think they *need* checking, but I can't be arsed now. It's not such a trivial job on the horizontally opposed engine - especially when I can't get her up on ramps. But there's definately fuel getting to the cylinder - 'cos I could smell it... Spark - could be lousy, but there's definately one at the plug... and I've tried a new plug :(

Cheers for the suggestions tho'
