  1. Good turn-out last night  - I now now have a 635csi and a Prince Skyline on my ever expanding want list.

    I'd be keen to try the same venue again next month before crying too much about the parking  - I wonder how much was School Holiday tax? 

    Also the GC from Burgerfuel said he'd accidentally park his ute and trailer across a few carparks next month if we wanna try again. This has nothing to do with me winning free fries after playing burger-pong. Who am I kidding. Free fries motherfucker!

  2. I'll be there - but have mismatching tyres. Got the burn-out tyres* on the back y'all.

     

    *T's & C's apply,. Burn-out only possible if someone covers the carpark in a thick coating of lard, ky jelly and pamolive dishwash. Burn-out will actually be a combination of wheel bearings, tire rub and clutch exploding. Credit criteria and a $99 dollar booking fee apply. Goes hard for what it is. Cut cat M8. Like a shit on a rail wrapped in blanket.

  3. 3 minutes ago, Mr Vapour said:

    pop over and bring your extra 4 sets of plugs. 

    We will give them a clean up in the blaster, get them super clean. 

    Shit yes. Awesome. Planning on using your services a fair bit once she's running - seen what you can do with throttle bodies - awesome result. The whole engine bay looks like the Exxon Valdez used it as a port for a while .

  4. Small update - trying other stuffs:

    As previously mentioned, engine is running rich enough to kill a set of plugs in a few minutes.

    The metering unit requires vacuum to control fuel supply. Not enough vacuum  = rich.  There are three throttle bodies, each used for vacuum supply. 1/2 = dizzy advance, 3/4 = metering unit, 5/6 = vacuum reservoir then to brake master via one way valve. For those playing along at home, the screw on the end is the idle control. In/out  etc. You can check if your butterfly's are closing correctly by jamming your finger over it. Stall = good.

    So, checked throttle bodies for leaks, including balancing pipes, other pipes etc. All seemed ok. Possibly small shaft leakage but I'll leave that for now.

    Threw a vacuum gauge off a T inline and got a bouncing reading under 6hg. Not good. Factory says 10-12hg. Checked other throttle bodies - same deal.

    I'd previously checked the tappets with @Threeonthetree and we reset to factory 10 thou just the other day. Then it struck me - has someone put a more aggressive cam in this? A bit of research suggested it might have something like a Piper fast road cam. Opened up the top and changed clearances to 16 thou. Reconnected vacuum gauge and what do you know. 12hg. God knows what cam i've got - this is gonna make setting things up more interesting :|

    Anyway, now with the correct vacuum the metering unit has the prescribed travel on the control link  (see previous post for pic) but, alas, it was still running too rich. Had a think about adjusting the xmas tree of fuel delivery on the metering unit but knew this might be a tad out of my skill set so tried something a little more creative.

    Knowing there was likely some wear on the follower and control links of the metering unit, I decided to sacrifice some feeler gauges. Warmed the car up, and slowly started increasing size between the follower and roller on the control link until maximum idle was achieved without stalling the car - the theory that this was backing off the fuel cam. Got to 18 thou and found what I assumed was a sweet spot so cut the gauge in half, stuck it in the metering unit and road tested.

    Findings so far :  car not as rich at idle now = win! Car now has no top end pull = lose. 

    Next steps: Back of the gap a bit more between the control roller and follower and try and find a compromise between idle and full noise, check ignition advance, play with fuel load fuel setting screw.  PI Lyfe.

  5. Lil more progress however she's running oh-so-rich - to the point that I keep fowling plugs / black smokes.

    Been through a few plugs now trying to diagnose. I reset the max fuel screw to factory spec on the metering unit and fluffed about with trying to balance the throttle bodies. These could do with a bit more work, but I don't think they are out enough to cause this kind of enrichment. Also, overfuel/choke lever is resetting per guidelines. Blew the over-fuel return clear with the compressor, and then checked for vacuum pressure to metering unit  - which seemed a bit low - however I might have also fowled a plug in this process. Did a compression check and all around the 160 mark which I would consider healthy. 

    Did a dort sans bonnet up the road

    So, next steps (and yes - please comment/suggest) are : Double check ignition side -  try another coil in case it's weak, replace/clean plugs again, test lead resistance,.

    Vacuum to Metering Unit: more vacuum diagnosis across all three sets to see if any difference with side of metering unit to check travel. 

    Metering Unit: Double check fuel pressure with another gauge, then if that all turns pull metering unit again, replace all seals / rebuild and/or start playing with calibration adjustments under top cone of metering unit. (I don't want to do this.... see below) Also - all o-rings at both injector end and metering unit end could also play into problems.

  6. Post Nats update:

    Tightened front left wheel bearing, rolled guards a bit more, installed oil, de-greased some bits, changed polarity of windscreen washer so that it squirts instead of sucks. Will remember to take pics next time. 

    Things to do: Fix brake shudder.

    Still driving it lots. Weekend jaunt on some closed roads (it said ROAD CLOSED AHEAD, not road closed....) around the Clevedon coast with some OSGCs.
