Well this is the weird thing. As the fuel gauge is so crap, I use the trip meter. The gauge was reading 0 but had only been doing so for 50 miles or so. The trip meter from what I thought was a full tank was reading 200. I must have reset the trip at some point and forgot I'd done it. Senility creeping in. Generally I do fill up as soon as I hit zero, knowing I should at least have 100 miles spare capacity.
I'm also gonna invest in a mini jerrycan of some sort.
At one piont the guy was muttering about, hoping his apprentice had been storing break cleaner in the can also.
It ran fine after adding new fuel so I'm going to take the old girl for a blast today and hope for the best!!!!
