I finally braved the damp miserable weather to get into the garage and pull the engine part to investigate the issues of excessive breathing with my Uno Turbo engined X1/9 . Although the engine was completely rebuilt less than a couple of thousand miles ago a strong initial suspect was the inadequate fuel management system fitted when I first installed the engine.
To help in my diagnosis I found this handy guide to all things related to piston and bore damage.

My initial suspicions have been confirmed as damage as a result of over fueling stripping the piston and bore of lubrication. .
I've already upgraded the fuel system to something that can actually meet the requirements of a 180-200hp engine. I'll get the crank,etc checked while the engine is apart. The block will need liners installing as it is at maximum oversize. Another set of forged pistons will be required as well.
My expensive lesson learnt is to keep my ambitions in an achievable balance with my available resources and visa versa. Obviously I'll ignore that maxim at the first opportunity
