Posted: 28 Aug 2015, 09:35
hi guys
After my van always running rubbish and overheating all the time, and asking some questions on hear I decided to dump the faulty Double vacuum dizzy and replace it with a power spark SVDA unit.
It's a 1981 2.0 cu Engine with twin Webber 34 ict's.
I've had a look on the wiki but couldn't find anything to exactly answer my questions so here goes !
I watched a top video on retro fitting one of these units but can't find part 2 which would of answered my questions.
Before, it was timed at 5 atdc, however the video said to now time it at 8 btdc but it didn't show the process.
Which carb pipe should I now blank off ? Cos I've only got advance now
And do I leave everything connected and time it 8 btdc, or plug the pipe and do it ? And at what RPM ?
Any advice on the correct procedure would be great cos I've read so many different ways, I'm not sure where I am !
And the other thing is , my van makes like a whining noise which is alway there while driving , doesn't matter if you dip the clutch or put it in neutral .
It only does it while driving and gets faster with your speed. Although it's a contestant noise , it's a sort of broken whine if that makes sence , sounds like a wheel bearing and when my van just failed its mot on a bearing I thought that was it but I had it changed and it's still there.
I've just changed the gearbox oil ( comma gl4 ) but still there ?
As always any advice is appreciated x
