Turns out timing & mixture were fine. 6 month old spark plug with < 500 miles on it was knackered.

Runs much better now, but good to know it'll still do 50mph on 3 cylinders!

Thanks for the help though

I definitely blanked the vac advance off. I think the timing was 10 degrees and the idle was around 800

Thanks for the replies!

I have a BDL needle & red spring

Tyres are 235/75 15's. I was hoping to go to 31"s but am a bit reluctant now if that's all the power i'm going to get.

By looking at previous posts, I'm led to believe this is a timing issue, so 1, is it a timing issue? 2, what should th...

Greenlanes or Byway Open to All Traffic (BOAT) are marked as pink -+-+-+ other routes that you may be able to drive are marked as pink dots (other route with public access) In both cases you ...

Ha! Thanks Scott.

Hi guys I'm doing a rear brake disc conversion and i thought whilst I'm at it i'll get some vitara calipers to go on the front and use my front calipers on the rear to improve my braking all round. I picked up some vitara calipers last night and I noticed that the piston on these are smaller than th...
