If all goes to plan and the 911, currently at a specialist dealer, gets sold - big if, as due to #@%$ uncertainty I think, nearly all the classic cars for sale in November I've been watching are still up for sale - and if I can make a deal at the right price with the current owner, it will be this, a 1950's Alfa Giulietta Sprint. Worth a lot when done, it depends on what's missing or needs doing, the current owner is no mug and will have a good idea what it's worth, but it's going nowhere until I'm ready, I've been told. However that'll be a thread for another board if it happens. The CB750 K1 may have to go too if I need the garage space and cash.
Here's an immaculate finished restoration for sale, note the eye watering price!

I'd follow a thread on a 1967 Bomber rebuild Roy, as Ash says, many differences, sorry I can't help with a wiring diagram.
I had the CL450 running again this morning and once warmed up I got a nice strong tickover, but them as I stood back and watched the revs shot up for no good reason and I had to switch off! Not sure what that's all about, but fuel was dripping from the left hand carb. There seems to be a fine line with the float level between no fuel in the bowl and too much, I need to investigate.

Not sure if it's #@%$ or just a natural correction but some parts of the classic car market are very soft at the moment.
MrDavo:
Certainly nothing much is moving at the moment, a friend of mine is looking at E-types as they've noticeably dropped, that could well be because sellers were over optimistic in their expectations, as you say market correction.
Anyway, woo hoo! The post had a buff envelope from Swansea, I now have an age related 'H' registration, and can get on with ordering a black and silver numberplate. :D :D :D Once that comes its a call to the insurance company and 'head out on the highway' time, now I have got my motor running.
Along with fitting a nice new pair of pattern mirrors which arrived from Thailand, It's just about finished, though I still have to play with the flooding carb, if playing with the float level continues to be elusive I may try different combinations of needle and seat, I currently have the original needle and an aftermarket carb kit seat, with a new float. A real ball ache but I'm sure I'll sort it eventually. At the moment I can get no fuel in the bowl, or dripping out of the overflow. Looking at the Honda Twins forum it seems I'm not alone. Somewhere in between must be a happy medium.
MrDavo:
Up and running, but still waiting for a number plate to be made.
She wouldn't fire at all yesterday, I realised I'd flooded her and took the plugs out to dry, today I found still no joy, the offside plug wasn't sparking at all. A switch to the original plug she came with sorted that out, so BOTH new NGK's have failed, I got them cheap as chips off eBay and wonder if they might be fakes? She is now back on the original plugs that she came with! It reminds me of a lad I used to know with an RD250, his pockets were always full of spark plugs as he kept fouling them. Can anyone point me at a reliable source of NGK spark plugs?, I don't mind paying a little more for the guaranteed real thing.
Anyway I got it running, and took her out for a first ride, down a local ancient dirt road that has had no maintenance since the middle ages, but noone has told satnavs yet. You occasionally meet the odd stuck wagon with a very flustered driver.
The bike went OK, a bit of a handful on the really rough stuff, and the carburation isn't quite there yet. I may get the carbs off again (a real ball ache as you have to take the tank, side panels and air filters off first) and use the carboard float lever tool (I have a drawing in my Clymer manual) to get the float levels better than my trial and error setting, . At one point she cut out completely and I coasted to a halt, it turned out that the low tech bent piece of metal that rubs on the choke lever needs tweeking, as the choke had vibrated to fully on, killing the engine.
When I got back, with the bike up to temperature I got the screwdriver out and adjusted the tickover again, I was quite pleased with the result:

Woodside:
My 450 would wet the plugs for fun..
I found when starting do not even touch the throttle not even a bit...let it catch on the choke then roll the throttle on...never failed...
When I sold the bike the guy called in a bad mood saying it wouldn't start....yup he had wetted the plugs..New plugs and he was away...
On a foot note I've found that when the new ngk plugs have been flooded they are toast and never the same again..
MrDavo:
Thanks, after reading your post I’ve ordered 4 new ones, I can keep a spare inside the plug spanner in the toolkit, also I’ll remember to keep away from the twistgrip when I start up, I didn’t know that and have been giving her a touch of throttle when I try and start up.
