hey guys iv been stuffing with my ute i set it to base timing 6deg n dwell to like 52. it ran like crap no balls at all. then i read this forum n did the performance timing rev to 4200 set advance to 35deg. didt wanna start but went ok. so i backed it off a lil bit but it only revs to 4400. any help would be great.

what colour are your sparkplugs now?

I once hit 7200rpm with my old a12, it had extractors, home made dick smith electronic ignition and a down draught weber. 2nd gear and a very long straight.

Where was your timing?

4400? stocko motors should be able to sit on 5500 all day and bounce up to 7500, i think with gx double vaulve springs they rev to 8500

ive got a 1985 a12, running on unleaded with a 32/36 weber. what should my timing be at? its way off now cause its down on power and munching on fuel. and what kind of kms should i get out of a full tank?

This was a few years back now, i seem to remember it being advanced slightly, but not too sure. I tryed several times to get it over the 7200 mark after the rust got the better of it and it was good for nothing other than parts, but never had any luck. Maybe if i played around more with carb jetting and timing it could have gone further.

9500rpm maybe thats got something to do with my 13bt haha

I'll tell you what mine does after this weekend :)
But if it starts pinging due to my tuning I'll not rev it hard :(

my old L20b went to 10000...but that took alot of work
