Best way is to use an exhaust gas sniffer. No, not your own nose! 😀

Gunson Gastester

I've got a rather ancient older model, found it very useful on older vehicles.

That’s what I’m looking at Alan.
Mixed reviews but worth a punt at £125.

Anything else would need some judicious use of Dave Ancill’s Man Math Calculator to be able to justify it!!

Went ahead and removed the inlet manifold and ripped the gasket.
New one on the way.
The nuts came off easily. Which was a surprise. The outer pair look a little more rusty so left them alone which means I haven’t disturbed the exhaust ports so may get away with splicing the gasket in.

Still got the old version with the analogue needle, a Colourtune see-through spark plug, the Hi-Gauge compression tester, a very old Gunson timing strobe and the 'autoranger' multimeter thing which does RPM, dwell, volts etc. from my old days playing with the Sprite, minis and such!

Is that the set in the yellow plastic case?

My man maths calculator has been fine tuned, it can justify most outlays, give me a call if you need support 😁

I don't think they do exhaust gas analysers in carbon fibre.

Inlet was black, has cleaned up nicely.



Next up a repair to the heat shield.

Watched anedition of Bangers and Cash today and they had 2 MGB GTs - both special editions one from the last produced and a 1979 MG Midget. All had delivery mileage on them. A gent in Ireland had bought them and just put them in his garage. I thought they would go for big sums but each sold for around £10k,

Sometimes I think of selling Buttercup, but then I realise just how much I enjoy garage therapy working on her.

Paul, I've seen that one. They were very original, right down the to the transport plastic on the door cards.
I daresay if they'd go into one of the big London Auctions, they probably would have fetched a lot more.

Wilf, agreed. Garage therapy is the perfect antidote to refurbishing offspring bedrooms and other such DIY demands from her indoors.
Although the BGT is my FiLs, I'd hate to see it go. I thought I'd feel that way about the Midget too, but getting in and out of it is a young man's game nowdays ;) I have considered selling it recently.
Youngest son's ears perked up when I mentioned it as he's very keen to have an MR2 .... possibly a blue one :D

Jeez Wilf, you would miss her without a doubt, unless it was to exchange her for another classic

A week on, the manifold gasket finally arrived.

The nuts holding the exhaust manifold are free so plan it to just change it.
I’ve toyed with pulling the head off and getting it rebuilt to run on unleaded fuel. Peter Burgess will upgrade my head for around £300 but the mess that is Brexit is mucking up shipping between NI and GB. I’ll leave it until after Easter.



I’ve added an aluminium panel to the heat shield due to it going a bit thin over the centre branch, and given it a quick coat of aluminium spray. The original heat shield is not available due to it being made of an asbestos fibre material. New stainless steel versions are available but not moulded to the same pattern.

Should get the carbs back on this week.
