I'm in the process of refurbishing the carb on BSA Bantam B175.
On removing the carb I noticed that there was no 'O' ring as shown on exploded diagrams.
Also the order of gaskets from the carb was... paper followed by 'Tufnol' washer/gasket. The exploded diagram for cylinder parts show the gaskets reversed, i.e. paper washer sandwiched between the cylinder and the Tufnol washer
The gasket set contains a warning slip stating 'do not use 'O' ring and gasket on same joint surface'
Before I commit to putting the carb back on the bike, is anyone able to confirm that the order should be........ carb with 'O' ring fitted, then Tufnol washer then paper gasket, then cylinder
Sorry if this has cropped up before on the forum, but my searching technique is not particularly efficient
Thanks for taking time to consider this
