While my car was up north for a while i asked RVT to check the timing and throttle pot settimgs.
He says the timing was out 12 degrees and wanted to know why the pipe was disconnected and i only had one throttle spring.
My reply was when i had it serviced 18 months ago i was told the vacuum bit was faulty.
I replaced it and it ran like a dog so removed pipe capped plenum bit and it ran fine.
As for spring i find the throttle a touch heavy so by removing 1 spring it's better but i was told by doing this causes problems with the butterfly and can cause shunting.
Tonight reconnected pipe and spring and really made no noticeable difference
My conclusion is that the vacuum connected before sent the timing well off don't know which way though.
Not sure about the spring yet need to drive it a bit more to really see if theres an improvement.
Any of this make sense

mine was disconected when it was set up, i think its done this way when the timming is set up at 3500 rpm to acheive more power further up the rev range but does not drive as well lower down. thats what i was told it might be b... s.... ive put mine back and had the timming re set .your timming marks may be out as mine was .a chap tvrmike went through mine and he found the true drop dead center by bolting a guage to the rocker cover box and cranked it from the pully by hand till the guage shows tdc .it was a bit out.my car does not even show the degrees on the pulley .mike as a pre serp and its a lot easyer to work on his engine .the timming lights now does the degrees for you so you don`t need the timming marks each side of tdc . i must say the car pulls away better with the vacume connected there seems to be a delay with out it .i would get it sorted .
forgot to say my car runs very well , i blew a chap off at the lights in a 4l griff , it`s down to the mc1 cam , act induction kit k&n ar filter ,carbon trumpets and nearly forgot to say my driving .all i want to sort out is the e clatter noise when the engine is on load and the front end bang noise when i go over rough ground and weird angles .

According to RVT my timing is now correct something has happened because i now can reconnect pipe without any ill effects.
So the question remains was connecting it advancing too much?
It never pinked though and also got good mpg very odd.
Would only be advancing when a vacuum is present ie under light throttle or overrun. Not sure if pinking would occur under light load?So the question remains was connecting it advancing too much?

arb were replaced with thr rose jointed steve heath jobbys and nylon anti roll bar bushes.
It's the bar well that's what i found by accident whilst car on jacks.Full lock to lock there was a clunk narrowed it down to 1 ARB link higher that the other.
Now quiet when going up my drive on full lock.
Just a thought.
