Running Too Lean ?

So SAAB out first thing for a utility run - Harkstead/Ipswich/Harkstead. Basic stuff really. 

I had the disabled passenger - but as you can see I did not use the space.

PM the sun was out so I got the Caterham out too. Stutton first to drop off bags and gave EB a short run in it too. Then home and I noticed the yellow and green flowers and car combo before going out again.

Good run when 'pressing on' but a bit of carb spitting on low revs. Looking at the problem is could be a lean mix - often used to get through the MOT - umm that would make sense as it happened when I got the car back.

Could that be the Ferrari problem too ?

Finally I re-checked the oil on the dipstick in the Imp - and yes it is just that clean.

But then the sun came back out - so the E-type got a run and tank of 99 octane. 

Still the odd hesitation - oh and the squeaky pipes. Mind you the 'youths' at the garage liked it a lot.
