Help needed - engine tuning

Discussion in 'General Discussion' started by janerodger, Mar 19, 2015.

  1. Hi
    Is there anyone near Cheam in Surrey that could tune my engine.
    I've just fitted an electronic distributer and lined it up exactly the same as the old one but the engine is running fast and popping and im not sure how to adjust it.
    Thanks
    Jane

    Jane, there's a bit more to it than that. Don't drive it in the meantime.
     
  3. I`m out that way but couldn`t make it until sunday - as @zed says , park it up until someone`s taken a look at it .
    PM me if you don`t get anyone in the meantime .

    :hattip:

    As a rule that means the timing is far too advanced, turning the distributor clockwise until it runs about as fast as it used to will be in the ball park, but still don't drive it, too advanced can burn holes in your pistons so you need to know it's right.
     
  5. If you're stuck, and you need a seat of the pants 'get safely to a local garage' measure:

    Loosen the distributor clamp bolt...
    Start the engine and let it idle for a few minutes....(you're not loading the engine so even if it's way too advanced you won't do any damge)
    very slowly, turn the distributor clockwise until the rpm's start to drop
    continue to turn anti clockwise, until if sounds like it'll stall, then anti clockwise a touch....
    clamp the distributor back up

    If you bring your van to me for welding I can fix it whilst it's here , unless your wanting to drive it here :)
     
  7. Was sort of thinking if I got it running properly I could get the mot and attempt to drive it but can't find anyone local enough.
    Would a local garage be able to do it or do I need an air cool specialist?
     
  8. Autotechniks - 01372 878 464 the best but not the cheapest, he lives in Sutton and the workshop is in Epsom
     
  9. any decent garage with a strobe timing light and a Type 2 1600 manual should be able to get it spot on...

    1974
    Distributor type:
    VW 043-905-205C
    Bosch 0231 176 028
    5deg ATDC800-950rpm**

    1974 on
    Distributor type:
    VW 043-905-205
    Bosch 0231 170 034

    7.5deg BTDC 800-950rpm*


    * with vacuum hose disconnected and plugged
    ** with vacuum hose connected


    better still, ask the mechanic to check the timing advance at 3500 RPM....it should be around 32 degrees
     
  10. Thank you
