Mk2 Chopper

Right got you, so more sequential, yeah I can see why that might be a good thing, thanks for explaining. Gareth

I'm not sure I'm totally getting the need for a logic box, what am I not getting here, over the standard set up of an on off switch and the inhibitor switches? Gareth

Hi Mike, Yes my set up is still the original split cable, I was just wondering if you could incorporate a single knob to your modified one for ease of use. Gareth

I like the idea, very clever. Is it possible to link this to a single cable/control for ease of use, enriching the MU while increasing revs at the same time? Gareth

The sound gives you the clue plus loss of pressure, I'm also betting its the inlet side of the pump causing the issue. There should be definitely be a pre pump filter, more so than post pump filter. Gareth

Did you tell Rees Bros about the clunk? I'm sure they would be happy to double check the area of the diff to make sure and perhaps identify where it's from. Assuming the diff area is good, then you've got drive shafts/ UJ's and the same with the prop as the next obvious points of wear. Worth checking the rear shock/ damper mounts as has been mentioned.

I use Retro Classic 001 tyres in 165/ 80 15, they are the same tread as the XAS' successor. Transformed the ride and steering and just look right too. You won't regret going to the correct size. Gareth

When I adjusted mine, the colortune wanted a certain setting to get the flame blue, but listening by ear, it didn't sound as good, when I adjusted by sound the colortune was starting to go more orange, but it ran better. So I'm guessing he wasn't far out to begin with, but it made some difference to how the car felt. My problem was being over rich and sooting up the plugs and exhaust. I don't get any noticeable bogging. Maybe have a play with it, mark where you start from and try adjusting things, assuming you've done the other checks first I suggested, plus I forgot to mention I checked

Sorry to see you've had to do this repair, but you've made a weak frame a lot better, so some solace. Gareth

I seem to remember, just tapping it gently with a screwdriver and hammer will loosen it. Best to mark the position of the cylinders before you do so that at the very least you can put it back where it was. I went through all the others things first that can affect mixture at the MU, namely the vacuum amount. Throttle plates closed and balanced, air filter clean or new, tappets adjusted correctly. I put a gauge on the vacuum take off to measure the amount. Making sure you have no leaks from the hoses, diaphragm etc. Good idea to make sure the ignition side is working well too before final

Enjoyable video, thanks for posting it. I've done the exact same adjustment on my metering unit, I had a colortune fitted but it was the sound that gave me the most accurate setting. Gareth
