Hmm, still not idling happily. I have fuel in the pilot passage when I tickle.

Not sure if I should have a short or long nut?

Absolutely. The other thing I like about box spanners is that they are very easy to modify - with an extension tube for example, and you can often store them inside each other.

Me too, here:

It's all too easy to spend hard earned cash on something you hardly ever use.

Is that right? I haven't looked at the weather yet.

Maybe it will give me a chance to stop this riding lark and finish the FH mudguard!

I've just finished looking at the timing. I have the spark at tdc on full retard, somewhere near 5/8" btdc on full advance. I found two things, one relevant, one not. The points gap had closed to a few thou, which by rough maths would equate to maybe 15 degrees extra retard; secondly my mag cha...

That depends on how you choose to wire it up. The simplest way is to replace the rectifier directly and make use of the voltage control Ariel designed in; an option would be to use a modern regulator /rectifier and make better use of the alternator, maybe converting to 12V at the same time. A replac...

Thanks Nev, I see what you mean now. Jet block is a very good fit in the body.

I've got one of those - I'll check it out.

I guess I should be aiming for idle to be set with the ignition on the starting position, rather than full retard?

We're looking forward to seeing the thread continue John! I read it all again this morning.

Another gotcha on pre monoblocs is that there are 2 types of jet block nut (the big one at the bottom of the mixing chamber). I see from your photo that yours is the long type. This will lower the float level compared to the other type, which is shorter from top to bottom - thus raising the float c...
