| Beans,
I have just bought my first PB racer,i'm lead to believe it's a Blata B1 Replica,did'nt realise I'd be so taken with the shear grunt of these little things so I am currently looking for another (genuine)one for the wife. I've just developed a problem I thought it was fuel but when I looked at the spark plug I noticed there's a spring on top is this meant to make some sort of contact with the lead as I can see a copper end on the lead but cant see how it would make contact with the plug?? Hope you can shed some light on this for me. |
