Ok chaps ive been having this problem pretty much since i put the 1.6 in. Basically sometimes the car will run fine for a while, sometimes it wont start at all, and other times it will run then stall, then run then stall.

So far i have replaced both fuel filters and blown through all the fuel lines for blockages.
Running a low pressure facet pump that when the fuel feed is off the carb, it pumps plenty of fuel out.
Running the correct needle and spring.
Adjusted the needle correctly and fiddled till kindom come with it.
Timing is spot on because when its running it runs just fine.
Carb float has been removed, cleaned, and put back.
All plugs fire fine, coil is fine, dizzy is fine.

Everything points towards that it should be working fine. Have i missed anything basic that i should have checked?

......Battery?

Battery has been serving me really well, when the engine is in its "don't start at all" mood the battery keeps the engine ticking over nicely.

Blocked fuel tank breather?

Something carb or ignition related if not, nothing blocked on the carb that shouldn't be and vice versa?

When it dies have you checked for a good spark?

Fuel tank breather clear, as far as I'm aware nothings blocked that shouldn't be and vice versa. I'll get it running tomorrow then check the plugs, just can't figure out why it's so temperamental. Went on a 20 mile round trip the other day no issues, today 12 miles then nothing!

Odd.

I had a small crack in my dizzy cap contact. Looked fine on quick inspection

It ran fine but would bog a splutter sometimes mainly in the damp
Then it wouldn't start one day.
Then it ran fine
Then I went to use it and it fired up perfect but died shortly after.

Swapped cap and arm. Spot on after that.

Have you tried another coil? I had one that would randomly cut out

i have a spare coil i can try, will put that on tonight. will check the dizzy also and see if there is anything obvious, its a really odd/frustrating fault!

Coil changed, and used a timing lamp on eat of the ht leads and the coil ht and the lamp isn't missing a beat....?

going to swap the float over from my spare SU in case the one in mine has gone, just clutching at straws now, not sure what ill do if i cant find this fault....!!
