I have had an "AccuSpark" (simple, 'hall effect' type) system on my engine for over 2 years--no problems at all. At about £40, very cost effective.
Yeah Toshi I’m happy to have a go at making my own. What kind of material do you suggest for the spacer?

I measured an original and it is about 5mm thick. All you need is a small off cut of Bakelite, tufnol etc. If you have a local specialist plastic sheet supplier they could advise on the best heat tolerant material.
I can have a look in my box of spares tonight. Might be lucky
Cheers

So how do I access the fuel filter in the bottom of the fuel tank? I put fresh fuel in the tank before. However when I tried to out back the original Fuel pump there was no fuel coming into the fuel filter before th pump so I agree there must be a blockage between tank and pump. The tank fel filter needs looking at but how do i get to it??
There's a mesh filter over the pickup pipe attached to the sender unit in the tank. Six small nuts hold it on. I doubt it will be that blocked and I suspect it's a problem of just starting a flow moving. Once the entire supply pipe is filled it would empty the tank by siphonage if the fuel pump wasn't attached. To get that flow started, some people would suck the fuel along the pipe to the pump (me). Others would pressurise the tank using their mouth or a device, (no names mentioned) and others would be sophisticated and have a siphoning tool. You could also find a tiny funnel and with the flexible delivery pipe to the pump held as high as possible but no higher than the tank, fill the pipe with petrol, lower it to start a siphoning action and then quickly reattach it. Some people might call the problem an air-lock and this setup seems quite prone to it.So how do I access the fuel filter in the bottom of the fuel tank? I put fresh fuel in the tank before.

Hi Dave,
If you have access to a couple of 'V' blocks, a dial test indicator + stand and a 360 degree protractor, you could plot the valve timing figures for the Alquati camshaft
(so that we can copy the timing figures :devil: )
If doing this, remember to check what the valve clearance figure for checking valve timing is (might be in the official workshop manual, it's often different from the normal valve clearance settings) and position the DTI plunger this distance from the base circle of the cam lobes.
AL.
Not sure if I wasted my time but I have been on this all morning and some. I have the crank and camshaft in the crankcase and I dropped in a cam follower with another one on top of that upside down so it extended outside of the crankcase and gave me a flat surface to work on with a dti. Came up with the following readings direct from the cam.
INLET opens 50 before TDC , closed 70 before TDC
EXHAUST opens 75 after TDC , closed 30 after TDC
The lift on the cam lobes measure 0.28"on the exhaust & 0.285" on the inlet.
