It Sounds as though the carb more of a Smith's Carb as used on the Bullnose Cowley and blower Bentley's these have no spring or hydraulic damper but rely on a vaccum created by the inlet pressure. The more the vaccum the more the damper lifts increasing the fuel rate making the mixture richer. The overall mixture is set up by the jets. If you squeeze the throtle pedal the engine will rev freely if you jab the pedal it will stutter and cough until you take your foot off a bit. Driving the Cowley you have to have a very light right foot. Allthough you can use your left foot for the throtle as the pedal is in the center. I would suggest that no oil is used a bit of pencil graphite rubbed on the touching parts should do the job.

If you belong to the morris register you can access the morris 10/12 operators manual on the web site. It has all the info regarding cleaning oiling and adjusting the carburator.

[quote="Spike2"]Thought I would check out valve clearances and timing etc. which leads me to ask how do I time this engine, I cannot see any marks on the bottom pulley or timing chain cover."

You will probably find that the timing marks are actually on the flywheel /bellhousing cover, accessed by a small plate or a rubber bung on the top of the bellhousing itself. To get at this you will need to remove the gearknob, and take off whatever kind of cover you have inside the car on top of the gearbox. It may well be a rubber moulding. You may also find that there is a small scale on the engine block next to the distributor which allows the fine tuning by rotating the distributor a point or two either way.
The principle in cars of this era is usually that you set the engine with no 1 up to TDC as per the timing marks, then rotate the distributor so that the points are just opening. Fine tuning is then done by trial and error advancing and retard ing by small increments by rotating the distributor until you are satisfied with performance.
