Original ulster engine rebuild

[Tony Betts]

Hi dave,

The engine has always sooted-up so quickly its unreal. Which I've always felt was from the bores and the carb.

I've run it in the past on castrol straight 30 or might have been 40. But number 8 valve started to stick.

I run it since on castrol 20/50 and its started to stick.

I've bought halfords classic 20/50

I've always preferred 20/50. But if it continues, I'll go onto a detergent oil. I dont like it. But I've found it's ok if you flush and replace regular.

I know everyone will have there own miracle oil.

Thanks tony.
