As stated in title. I'm pretty much a novice when it come to timing my van so i need something with as little room for error as possible http://www.ebay.co.uk/itm/AccuSpark...iagnostic_Tools_Equipment&hash=item27cd3ac5e4
Looks OK - just spent more than that on a Gunson at Halfords. And that only does timing, less accurately but by twiddling a knob rather than button bashing.
all comments received and acknowledged. I was made aware that you have to do advance timing as well and running the engine around 3000rpm. Is there an easier way to gauge the revs other than using this bit of kit?
Basic one does the job good. That would be more suited to a mechanic who would make a lot of use of this tool. Wrth the money but not needed for basic mechanic in my opinion
I think you can just increase the revs until it stops advancing and it should be between 28-32btdc , if you dont have any means of measuring the rpm. could one of the more technical people on here confirm this?
Find top dead centre print out and use this to mark the needed degres on your pulley a small tin of humbrol white model enamel and small model brush is good for the marking Check the timing is correct at idle Raise the rpm untill it advances no more and check against the pulley with the timing light
Let me get this right. To check the timing at idle i need to put a mark on the pulley at 7 degrees (beetle engine) shine the timing light on the pulley and rotate the dissy until it lines up nicely (engine running at temp). Then I need to put another mark on the pulley at 30 degrees, take the pipe off the vacuum advance and put my finger over the pipe. Rev the engine until the new mark lines up? I will be trying this out at the weekend
edit, i brought the timing light in this thread. Do I need to just set the gun to 30 degrees and use the mark i've already put on at 7 degrees at idle? If so do I still need to take the vacuum advance pipe off?
If you use the settings on the gun, you just need one mark at TDC, not 7.5. Your pulley possibly/probably doesn't have a TDC mark, but there may be an indentation on the other half of the pulley which you can use to make a mark. Or set gun at zero and use 7.5 mark, then set at 22,5 degs and use your existing 7.5 mark to check full advance. The test for this is not just to rev to that mark, but to increase the revs until the mark stops moving which should be 30 degs at around 3000 rpm
