Well, ive got the van running again, it goes like this:
Put a new Carb on it after a thorough clean out with carb cleaner, with a new middle gasket.
Still wasnt for starting, now thinking its the Vac Advance gone duff bc i could suck on the Vac pipe for ages.
Replaced the Vac Advance unit, dead easy to do,
Remove the Two Flatblade srews holding the Vac unit onto the Dissy first.
Dissy cap off,
Rotor arm off,
Circlip on the top off,
Then using two screwdrivers inserted into the Vanes square holes either side i pried the Vane off, it can be a bit tough to get off if your nervous like i was about wrecking it,
Once its off there's another circlip to take off with fine a circlip remover, careful not to lose the Drift Key/small pin as i did!
I then used a 1.5mm drill bit instead, i cut the shaft end off to the required length, please note the original Height of the original Drift pin before removing the 2nd circlip or the Drift might come out with it and be lost easily.
Once the circlips and drift are out you should be able to simply wiggle the Vac unit off the arm, its quite simple.
Fitting is the reverse sequence.
Once all that was done, key in the ignition and it fired first turn.
Timing was out so manually set the timing to 5degrees before TDC as per Haynes, ive heard 7deg is good but waiting on a timing light to set it and the carb mixture right, apart from that it runs good, bit down on power but the timing gun should help rectifiy that.
Hope this helps people with carb problems to check all the vac pipes as this will help resolve some issues.
Thanks for all the help and advice from everyone, IL BE BACK!! Lol
