This one was delivered this morning (also free!)
Tried to get it going. When I got it, the engine was not seized, but it was a bit tight. Quick spray of WD40 to lubricate it, and it was a bit better. I think the bearings are bad or dry, since if I don't turn the motor for an hour it's sort of tight again, but once its free it turns perfectly. I'm sure once the engine is running it will fix itself.
Nice big spark. Not easy to see if there is a spark, because you have to pedal to engage the motor (you have to physically go forward, because engine drives off front wheel obviously!), at first I couldn;t see anything, because I was testing it in the sun. Easiest way was risk pedalling and putting my finger on the electrode. YES it works! It wasn't as bad as I expected, didn;t hurt as I thought it would (there again it's only 6v!).
I just have a fuel problem. The fuel was not going through, I found out that the fuel pump was not working, I think it is now (some stupid design, also acts as a reed valve). It works like a heart really, has a diaphragm that, with crankcase pressure/suction controls the diaphragm, and acting as a heart beat with the fuel, sucking it in the pump and umping it in the carb in the next beat, so there is no float chamber in the carb.
Got it coughing with a bit of spray in the bore, but I don't think it will need much to get it properly running.
No pictures yet, but I started oily ragging this one too, and its coming out lovely and black, not much ruse luckily!
