I have become involved in a discussion about timing and the relationship between timing measured in crankshaft position BTDC and distance before TDC measured in mm from end of upward piston trave. The calculation requires the conrod length, so, any sages out there who could share centre to centre dimension for a standard 1275 conrod?...
Thanks

You just can't trust anything nowadays---check check check-

John--Thanks for the thought but not running a welch plug in the cam hole, he's all sealed off with a bolt on steel plate and gasket. Sorry for the thread drift , now back to master cylinders----how's progress

Blimey Crikey Willy - all in a day's work then?
I have the same bellhousing drip - must get onto it. Or buy a tin of tuna & make a catcher.
While you're at it, better check that welch plug at the end of the camshaft?

No Les - I'll be using my nice cheap RamAir foams.
But before that - test-fitting the rampipes - I found that the new gaskets for my H1s have apertures an eighth too small. They really don't care, do they?

That's what I have William. No vent from the rocker cover, 1098 side cover with oil separator plumbed to the inlet manifold, sealed oil filler cap.

Very nice. So you'll not bother with filters?

Nice one--you'll actually be able to feel the difference driving it i reckon.

Something has gone right!! Having decided to re-use the fifty year-old rampipes that came with the car, I had a good look at them, and saw that they narrowed nicely to a diameter of approx 1 1/8", but then opened out to the fixing plate hole of 1 1/2" (see the first picture). A tuning modification!

I hunted round the house and garage for a 1 1/8" cylinder of some kind, and found a plasti...

Personally i think you're better off with everything sealed off except the hose to the carbs, any leak anywhere just increases the flow up the hose.
