Re: SU MC2 Dashpot and piston?

I have most of a carb available, including dashpot and piston but you will have to wait till I have put my own carb together for the miscellaneous other bits.

Re: Sterring head lubrication

The movement of these bearings is minimal and 99.9% of the load is on the lower bearing. All the grease does is to coat the bearing surface and prevent rust. In time, the lack of movement leads to the balls of the lower bearing making spherical dents in the races (Brinelling) which cause notchy stee...

Re: DKX4A advice please ..

You could only tell the differences by making comparisons with an original. I do have most of a distributor which could be used for that purpose but it is badly fire damaged. That said, assuming the basic length of the body is the same, the likely issue would be the gear on the end of the shaft. By ...

Yes, Simes, I did use old rods. The new Club rods became available shortly before I sold the bike but it went with a set of new Club rods as spares to be fitted. The buyer swore he would use the bike but managed only 300 miles in 3 years. The new rods were not fitted in his ownership.

Re: NG Iron Head valve job

I have never yet needed to ream Ariel valve guides. On an enclosed valve gear head such as yours, there is no danger of any need to ream.

Re: Hello New Forum member

I would echo what has been said above but I wouldn't bother with the camshaft spray unless you are going to feed your rockers from the return side of the pump (which I wouldn't advise on a Mk II). I did something like 36,000 miles on a MK II engined bike (Healey 1000/4) without the spray bar or sign...

Re: seeking Rear suspension spring for Sq 4 MK II Plunger frame

Phil, There must be someone who makes springs in your area but if all else fails, email me full details of the spring which means wire diameter, number of coils (exactly, so 16 - 3/4 rather than 17) spring diameter, spring length and finish of the ends. Photos can help in this. My spring maker will ...
