With a bit more than three weeks left until the Morgan will (hopefully) get its paint, I thought it is a good idea to do a few maintenance jobs on Maggie – the MGB GT. The front wheel bearings really need to get done now. As the brake calipers need to come off for this – it is a good opportunity to also change the brake fluid. And with the master cylinder drained – why not also overhaul the pedal box. The pedals certainly will benefit from new bushes and powder-coating them would also not hurt. Oh, and if I bring away some parts for coating – the old valve cover I got last year would also look better in black. Checking the valve clearance never hurts – as usual: the list is getting longer and longer.
The simple task for this evening was to quickly change the garage locations between the Morgan and the MGB. The Morgan started and ran flawlessly for the last two weeks – so what could go wrong? It should not surprise me anymore that if something can go wrong, it will go wrong. Suspect number One was the Weber. On the bright side I am getting much quicker now in taking it off, dissembling it and checking the base adjustments. I still double check the steps with the Haynes Techbook – but I only need to read the instructions once now. The jets and needle valve were clean, all adjustments including fast-idle look good. The only small thing that I am unsure about is the return spring in the AutoChoke unit. The replacement I got does not to pull back the lever arm as good. I am about to get a Weber 32/36 DGV 5A with manual choke – as suggest on the TalkMorgan forum.
Checking the Weber just confirmed me: it must be something else. And the only thing left is the old distributor. Fortunately, I already had a new one on the bench. Ok, dizzy cap off, finding TDC and making sure that it is really cyl1 that is up, wiring the timing gun and making sure the firing order 1-3-4-2 is hooked up to the dizzy correctly – it all went much smoother today as I have been doing this half-a-dozen times over the last weeks. The vacuum hole needs to be covered on the dizzy and it only took two tries – to get it to 8° BTDC. The entire procedure took two hours. I was able to switch the cars – but decided to call it a day. On the way back from the garage Miffi finally reached the 100000km mark tonight. Well, I took an extra round around the block and got to zero right in front of my door 😊
It should have been a quick garage swap 
Weber inspection…. because I can 🙂 
Techbook says that the jets could be dirty… but no: they are perfect 
float check with 8mm drill 
16mm (two drills)for the open position 
needle valve all good 
locating throttle for fast-idle check 
0.5mm between wall and valve 
Finding TDC 
Cyl1 check – just in case 
new dizzy – much smaller Mototronic unit 
I am qute sure that this is the reason for the problem.. the old dizzy is broken

Maggie will get the TLC she requires this weekend
