One advantage of the ghastly health situation and restricted movements is that I have finally found the time to continue dismantling my 1960 Ariel Arrow!
As with all these things the more you look the more you find and the machine has much evidence of bodged repairs and maintenance. I have now got the machine dismantled. With the engine on the bench I have a pair of bolt holes underneath the crankcase on the nearside with nothing attached nor any idea what they are for and also a single bolthole beneath the offside cylinder with nothing in it although on the other side in the corresponding position there is a bolt! Any ideas whether the empty bolt holes should have something in them?
Bear in mind the picture below is with the engine inverted.
Finally, apart from Draganfly are there any other useful suppliers of Arrow parts that people can recommend?
