Unless there's a punchline coming, I suspect it was only 'known' by those who had never looked at a map ;-)

Lowest part of the course is 23 feet above sea level at 23.96 miles which puts that just after Parliament Square
In fairness, Spannerman was only commenting on the point raised by Sticky re the carburation for two strokes. Spanners confirmed that it was the Crosby Valley that was the point on the course where you most likely to have a seizure on two strokes. I mentioned that it was this area, because it had the coldest air, particularly in morning practice.
I don't doubt that Parliament Square is probably the lowest part of the course, but I think Sulby straight will be pretty close.
I certainly don't think that the Highlander is the lowest, just the coldest!

Snap!
I fully agree that the Highlander is not the lowest, what I was pointing out is that it was once thought to be by someone and it carried on to be, the Highlander is the fastest part of the course though arguably.
With todays technology, it would be good to see speed traps on other parts of the course other than the Sulby Straight. It is certainly very fast past the Highlander. Cronk-Y -Voddy is another place I would like to know how quick they are.
When i rode two strokes there when they were the thing to have, you could sort of breath a sigh of rellief after the highlander you sort of knew that if they were going to seize they would do it from glenvine through to the highlander section. probably because of this people may have thought that it was close to sea level.

Hi Bill, I was always told Greeba Castle (I think that was the place, but certainly anywhere after the descent from Crosby)..... and I was always told below sea level.
Someone seized and crashed my RS125 in this area, not a happy time, not something I want to talk about either.

Now we have the benefit of hindsite and technology, would the 2 strokes have run any better now we know that they were being incorrectly setup when non of the course was near sea level?
Obviously there were other factors to to take into account, but if everyone was using bum information, how quicker would they have gone?

I remember that seizures used to commonly occur at Union Mills with the strokers. This woul dbe nothing to do with elevation. It was the first time they had been shut off after being held flat out under load uphill. High heat build, shut throttle, weak mix and reduced lubricant.

Mike, 1993 Stuart Jones from Crewe lent me a Stack System for my RC30 at the Manx which had a pick up system to the front wheel as well as the back and it showed the fastest part of the course was the Highlander by 4mph another example if you watch I think it was on board Brian Reads bike you can see the revs topping out at the Highlander compared to when he goes through Sulby, apart from being on the gas from Union Mills I think the drop down hill after the Waggon and Horses helped.

Bill, was that 4mph faster that the Sulby Straight, or all of the course?
Clearly, there are other parts of the course that are faster top end wise that the Sulby Straight.
Why do the orginisers put so much importance on Sulby?
Mike, 4mph was the difference between the Highlander and Sulby, many years ago they had the speed check at the Highlander then for some reason it stopped, I think the Sulby speed check started after Performance bikes did a couple of TTs there doing checks on speeds.
