need confirmation, to advance the ignition (1.9DG) turn the Dizzy anti-clockwise (when viewed from rear and looking down), searched wiki and thread but no help.

You really need to time it with a strobe.. easy to go too far either way..
Why do you think it needs advancing?

thanks Toomanytoys, taking your excellent advice and going to set it at around 8 degrees for lpg. I will adjust it with strobe and vac disconnected. The v in the pulley is set at 5 degrees and lines up with the centreline of the crankcase so I assume after adjustment the V should be about 3 degrees to the left of the centre line or do I have that a*** about face?

"U" groove is TDC, V is 5 BTDC (std single belt pulley) so a fraction further on from that.. measure the distance from "U" to "V" then mark that distance on the pulley.. go in between the 2 marks..

I will be running a couple of experiments in a couple of weeks, so should be able to report back...

Many thanks toomanytoys, much appreciated, can locate the V but don't seem to have the U (TDC) or am I blind as a bat?, will check again in the morning and drop a smidge of tippex on the pulley.

"U" is 1 side of the belt groove and "V" is other.. run your finger over to feel for it, wont be far from the V..

Thanks Toomanytoys, found the U (more like a dent no wonder I missed it!), tried additional 5 degree advance (10 BTDC) and noticeable improvement on LPG, particularly on gradients (or am I experiencing a placebo effect?) but have reset to to around 7/8 BTDC which is probably a better compromise. Let us know how you get on as it would be useful for all the lpg owners (post details in the wiki?).

10 would prob work, but its the petrol side that will cause issues.. yep.. when i have better info I will let you know...

I do know ANdy had a lot more advance than that on his "DF" on LPG only....
