My Mini then mis fired on the way back to the farm shop, stalling, running like a crap and Colin said he could smell petrol. We checked it over but could not find anything wrong. I decided to limp it back and set off having trouble keeping it running.  1 mile up the road it came back to life, idling cleanly with no hint of a problem. It is just the worry now, next time I use it will it behave.

 

Muck on the float valve.

Or muck in the carb bowl blocking jets?

Jets? It's an SU isn't it?

Bit of grit on the needle valve in the float chamber, fuel pisses out and it runs rich. Grit clears, runs fine again.

I’ve no idea? Just assumed an eighties carb would have jets?

No jets in an SU. It relies on a varying venturi piston and attached metering needle to vary the fuel flow based on load and engine speed.
