Fitting a cam. Complete rebuild

Discussion in 'Mech Tech' started by Borninabug, Jun 30, 2015.

  1. Non vac 009. The carbs have no vac take off
    I did put a vac dissy in to test where it sat and it did cover the m8
    I'll try the light on the starter I've got a remote starter rigged with an old lightswitch

  2. I gave up last night
    I finish work for five weeks today so will get to the bottom of it.
    Thanks for all the help guys I probably would have set light to it by now without the help and encouragement

    When I built this up I put a dizzy in at the same time as the drive to ensure it was at tdc for no 1. I could see the cam lobes were valves closed and the con rod was pointing at the ceiling ( engine on it side) I did put the drive in wrong 1at time but because the engine was in half popped it out with my finger and turned it. When in right and checked with the dizzy I left it in there to keep it from dropping out

    TBH it shouldn't really matter about the distibutor drive - you can turn the body, attach the leads and get it running however it's installed.However assuming you did get it right which I reckon you will have done, a pic of how the distributor is orientated after static timing would be useful. I realise the distributor in your pic was fitted to keep drive in place only, but for reference I'd expect to find it rotated about 45 degs clockwise from where it's shown in your build up pic above.
    And you might have just flooded it yesterday.
    Fingers crossed for today. :thumbsup:
     
  4. I do feel like it's something very simple. I will get there



    One day

  5. as a quick check and to eliminate the disi position question try moving the leads around one post at a time - this will put that potential issue to bed...
     
  6. ^ In that pic, isn't #1 at BDC not TDC?
     
  7. Did this last night
    No luck
     
  8. Possibly
    But the crank had Ben turned after mating two halves to make sure everything turned
     
  9. So I've got tdc

    This is where the rotor points

    This is where the leads go in order

    I would hazzard a guess that this is No.3 TDC.

  11. I think 009 dissys are 180 different to the vac advance ones I'm not there atm so will compare them later

    They are 90 degs different, that's why I think you have number 3 there.
     
  13. This

    :thumbsup:

    And looking at your points, you're a fair distance off opening when the engine is coming up to tdc...

  14. Thanks guys.
    I am knackered. I've been working and doing nights on this for a couple of weeks now Leaving it tonight as I think it is snow blindness now. I just can't see the wood for the trees. I am normally very logical and can see things straight away. The longer this takes me the more annoyed I am getting and therefore less likely to work it out.
    Fresh eyes and a no alarm start tomorrow may help

    Teachers hols:)
     
  15. It's fuel. Too much of it. It runs but floods. Need to get it right quick to run the cam in
     
  16. Cam run done. Popping and farting needs tuning but done:):):):)

  17. Nice one! :)
     
  18. I am not out of the woods yet. It may take some time to set this up properly. Once again thanks to all who have watched, commented and helped along the way. This all started with a dodgy FI system that was buried under six inches of rat poo when I got the van. It worked well. Sometimes. Others it coughed and misfired. The lifters were knackered so I gave it a go at replacing with new ones after the old ones bled down every five minutes. The break in was duly done but the cam didn't like it and I lost 6mm of 1&3 exhaust and who knows what off the others. This took me ages to notice while battling to get it running right. (Who can see valves opening and closing while turning the ignition key?). When I opened the engine up the centre main had all but collapsed so it was good timing getting in there. The new cam and a full set of bearings went in with a parts bill of about £600 including clutch, oil etc.
    I wouldn't do this if I didn't love the challenge and the sense of achievement but the fact that I have the support of TLB makes it even more enjoyable and gives me confidence that I will resolve any bay related issue.

    THAKS GUYS
     
  19. Been out a few times and all is now good. Still need to balance carbs properly but the local garage has said he will lend yes lend me his snail type carb balancer. Probably as he cant be bothered fiddling with my van but still a very kind offer.
    I had one moment of panic as I took a rack of bikes out on the last trip. The extra weight on the tow bar made the exhaust touch the bumper and but only when I dipped the clutch to change gear. I thought it was the new clutch release bearing ready to explode. I think I can adjust the angle of the engine using the front mount on the gearbox
