MG
The Classic Marque

I feel that GL5 is a bad choice. Could damage the brass and bronze components. MG recommended 90w Hypoid Gear Oil in gearbox, axle, and steering. (GL5 was not available in 1954.)

Few brands of GL4 Hypoid gear oil are available today. Too many trusted MG specialists recommend Redline MT-90 to ignore.

Interesting Len. Currently in Le Mans with my MGA Twin Cam for the Le Mans Classic 24Hr and just had both SU’s banjos go loose on the way down from the ferry, leaking petrol down the side of the engine and leaving a nasty dirty puddle underneath. Thought it was an engine oil leak but it turned out to be an oily/petrol stain due to the loose banjos. Tightened them up and all’s well but need to ...

Amazon has MT-90, don’t even have to get up to go get it, next day delivery here. George

Doesn’t answer your inquiry, but I’m surprised to see you can’t find MT90. It’s available at my local auto parts store.

William - sorry they are the original HS2's - it was late !

I do have another set of carb - I was unsure about buiding a good set out of bits - I tend by nature to keep assemblies together - so that's good to know.

Guy - I have tried that - but as William as suggested using my spare set for spares I'll try that next - thanks.

Thanks Rob - I'll do some more looking into what I ...

The float chamber angle is set by the spacer between float chamber and carb body. Also what car the inlet manifold came from. Mini manifolds will fit Midgets but you end up with a dent in your bonnet because a Mini manifold has a bigger angle than a Midget inlet manifold.

If you link to this page it's item 66 that sets the float chamber angle depending on application.

Andrew Neil. Is he wrong?

Sadly, he's not. The lights are going out.

-- "As I watched PMQs on Wednesday and looked at both front benches, something dawned on me I had hitherto only vaguely perceived: we are now a country bereft of a credible or competent governing class on either side of the political divide.

Sometimes just undoing the dashpot top and turning it so the screws mount through the next set of holes corrects the misalignment. Similarly, lift the piston up and down with one finger as you progressively tighten the screws does help. If neither of those sorts it, then centre the jet as Willy decribes.

If trying a differ carb set up the HIF44 really does work well on a modified 1275 like ...

To get the piston to drop properly it just needs the jet centering up--could you use the float bowl off another carb to replace the angled one if you have one suitable-
What size are the carbs on it now, you mention the originals were HS4's (1 1/2") but originals would have been HS2 ( 1/4")wouldn't they-?

Good job, didn't doubt you for a second.
Would be interested to know the result from the dyno man when you go.--Is this a factory v8 or a conversion car, is the engine modified at all
Cheers
