Re: Choke coupling

Have you tried loosening the clamp at the front carb - that's the bit with the nut on top - it allows the mechanism on each carb to be matched. That will allow you to move the linkage on the front carb until it matches the rear carb.

Re: MGB Cooling

Paul, I know it's currently hot in Essex - it's quite warm on the west coast of Scotland. The MGB as designed should be able to cope with the sort of temperatures you are currently seeing. After all, it was built to be exported to the USA which can get very high temps in some areas. Have you found ...

Re: Jumping out of reverse

First make sure the gear lever isn't fouling on the edge of the hole in the tunnel. If it can't go right back, it could cause jumping out of gear.

Re: Safety Fast March 2026 Living with the MGB

It seems a complicated way to build a car, but I guess it has always been so.

George, I see you have a BSA Bantam. I first rode one of those in 1965! The speedo only went up to 55 mph and my brother and I tried very hard to get it there.

Re: Colour coded wheels - yes or no

Not an MGB, but my ZR 160 has the original wheels painted in black with a metalflake finish. That's how it was when I bought it and I like it.

Re: Mgb thermostat

I've said this before, but in my humble opinion after 40 years of MGB experience, the oil cooler is entirely unnecessary in the UK climate unless you are going racing, or such like. At the very least I think you should cover the cooler with foil to prevent the cold air passing through it. On my 1800 ...

Re: Carb rebulit

I think Ian is right. The problem is the depth (or lack of depth) of the filters. I reckon the standard filters would be better than those. I had K&N on my B (now sold) and they flowed so much air the carb needles needed changing to keep the mixture right.

Re: Carburetor Hose

Sorry, I don't think that Steve is right. The extra hose connections by the dashpots is for the crankcase breather system. Have a look at the pictures on Paul Hunt's site mgb-stuff.org.uk

The overflow pipes Steve refers to are normally on the top of the ...

Re: Steering wobble

Does a '77 B have Rostyle wheels? These can be hard to balance perfectly because the hole in the middle, where wheel balancing machines locate, is not always dead centre. My long experience with MGBs tells me that the design of the front suspension and steering is particularly sensitive to wheel ...
