Modern Petrol!

[Robin Boyce]

I must apologise to any participants of the LCES Summer Tour last weekend who were held up by my recalcitrant Chummy, invariably on the narrow steep hills you had nearly conquered, and to thank the kind enthusiasts and passing strangers who gave me uphill push-starts.  The diagnosed fuel starvation was caused by this brown, resin-like matter in the tank.



Local light-carists suspect a residue from the bio share of the unleaded that has settled out during the winter lay-over.  My own fault for avoiding the cold in my old age.
Any other thoughts on this annoying problem (not my old age) would be appreciated.

That looks like shellac to me

Well, there's a good selection.  I'll leave the biltong thanks; the tank has never been sealed as far as I can see (but that might mean it has all dissolved and formed the stuff shown); and I don't know what shellac would be doing there.  Unless the other half has been using my petrol in desparation to remove her nail varnish.  I'll just hope for the best.
