    78,
    Sorry for any confusion, but I think you are confusing 'total' timing with idle timing.

    Total is what the engine wants under load at high rpm, though it may come in at lower rpms. There is...

    LX,
    Why don't you get a GM HEI for it? Put your own curve in it so you can run MVA. $80 brand new from Road Star in Sydney. I would be happy to set up the dist for no charge. I provided the...

    I do not think Summit is the problem as far as shipping goes. There is a HUGE amount of product on b/order in the US. Some of it could be due to the China/US trade war.

    What he is saying is he is blipping the secondary shaft.

    In that case, I suspect fuel flow from the sec T slots would be correct because that is the only airflow into the engine & is at high...

    Not a silly question. VA, whether ported or manifold sourced, is a load sensitive device, based on engine load & vacuum. That is the beauty of it. When you go to full throttle, vac drops to zero or...

    Yes". many engines run 'perfectly fine without 35-40*', on, say, 15* init timing . The point is that many of them would run better with 35-40* of idle timing...or substantially more timing...

    Agree with EH about more timing.

    If I am reading the numbers correctly, you have a total of 40* at cruise. That is really low for 9.0:1 CR. I would add at least another 5 -10* of vac adv. That in...

    I think most likely cause is a vacuum leak or valve adjustment [ valves not fully closing because of wrong lifter pre-load adjustment ]. Also check the PCV. Block the PCV. If vac is then steady, PCV...

    The idea is to try 'balance' the force or load on the t/shaft to minimise wear. So there would be some adverse affect if there is a spring pulling in the same direction as the linkage/cable. It might...

    Two points.

    Don't use RTV where petrol or fumes come in contact with it. It softens up. If you are sealing a threaded hole in the induction system, use Loctite 567 Pipe Sealant.
