Bit of an update:

Finally settled on a position for the engine after a few attempts:

I had a Vespa JL exhaust kicking about and decided to put it on to see what fitment issues there might be. Held up with cable ties but still quite solid.

Quite a good fit as it turns out :o

I had the carb on with the throttle connected so thought about trying to start it.

Timing was set at a static 17* and i quickly connected a cdi.

This left the petrol. I quickly improvised a sauce bottle with a tapered end, this fit into the fuel pipe......another result !!

Choke on......started third kick :o

Couldn't believe it, revved cleanly and was quite responsive. Bits were rattling everywhere so killed the engine.

Gave it another 10 min and tried again. 4 kicks this time but started cleanly.

Tidied up and went in with a big grin on my face.

So i could test drive it i needed a petrol tank. With the quirkiness of the frame i decided to make my own.

First i made a template out of a cardboard folder:

Nice fit in the frame

I decided to 1053 aluminium for the tank. I made it slightly bigger than the template as i wanted about 9L. A rough calculation gave me just over. i'll have to wait till it's welded to check but it looks about right. Initially it's tacked up and i've still to fit the tap, filler neck and fastening brackets.

The tank looks a bit low but the fixings will lift it higher.

Next job is to finish the tank and add some strengthening braces to the frame.
