Sorry Anna The engine I am assembling DOES have 2 studs with nuts and 2 Allen bolts to hold the carbs on.
The two front head fixings on every Norton twin that I have worked on since 1971 has two 5/16CEI studs in the barrels and this Manxman has two BOLTS. The current owner did not change them, and we believe he is the first to dismantle this engine back around 1990.
Well after looking through my 1961 Norton Manxman parts manual parts numbers 23369 x2 inlet port sleeves parts numbers 23394 x2 distance pieces for carburetor part number 23563 studs x4 & E3231 nuts & washers for studs Now argue with the 1961 Norton Parts manual and there is no mention of Allen bolts in this part section grope P of the 1961 Norton Manxman parts Manual[/quote]
We agree no manxman in MY1960 see here the FACTORY brochure OK

Here is the FACTORY pix of the "62"manxman

Look through 61-62 FACTORY parts book ps214 on page 56 for the "allen screw" 23395 carburator fixing screw

I have heard of a mythical parts book not FACTORY but instead Berliner in New Jersy USA
Is this what you are refering to? IMHO a parts book from those days is a snap shot in time and NOT a final authority that anyone including you "MIS Researcher" should get so wrapped up in.
For example this Norton memo is an example of the fluid nature of a production environment. Sometimes as few as 30 machines before another change!!!

Well this is the wrong parts book For the Norton Manxman It HAS it own Part manual And has 35 pages in it and is in A4 size NOT A5 size So you all have the wrong information My machine was built December 1st 1960 Its stamp marked to this date and the Magneto has the same date too Only I have the Norton Manxman 650 factory records
SO "Mis-Information",!!!!! My friends genuine Norton Manxman has 2 Allen bolts identified as 23395 carburetor fixing screw and what you are trying to prove is that rocking horse poop does or does not exist. And I'm not buying it.[/quote] NOW ONLY the Singel Carburettor fitting have 2 Allen key bolts The Twin Carburettor were fitted to all Manxman 650 Twins unless the dealership changed them for you to single carburettor fittings
