An attractive lightweight outfit. The latest Allon two-stroke with a Canoelet-minor sidecar and Rally wheel covers.
A new type of exhaust pipe connection which takes the place of a manifold cast on the cylinder.
The Allon spring sidecar coupling. The bayonet fixing can be operated by hand with ease.
Two views of the saddle tank of the Allon. Note the large filler caps, connecting pipe, and the sump over petrol tap.
Allon Two-stroke Improvements.
Detail Alterations to a Popular Lightweight.
IF evidence is wanted to prove that the two-stroke lightweight is as popular as ever the order files of the majority of two-stroke makers will supply all that is needed. Messrs. Alldays and Onions, for instance, have been obliged to refuse further orders for some time, as the demand was much in excess of the present output of their works at Fallows Road. They are not alone in this respect; many other manufacturers are "snowed under" with orders. Conditions are improving, and every week witnesses progress. Although there are many improvements in details which make for increased accessibility, the latest models are substantially the same as the former Allon production.
Unit Assembly.
The engine unit is now assembled and aligned complete with the gear box, magneto, and silencer on the bench, and the whole placed in the frame en bloc. When being decarbonised, the cylinder remains in situ, the crank case lower half is dropped, and with it the flywheel, shaft, connecting rod, and piston. The necessary scraping can be done through a large port in the head which carries the release valve dome. The exhaust port has been redesigned, and the pipe is now attached by bolts through two lugs on the pipe.
Frame and tank construction form the principal improvements. Messrs. Alldays claim to be the first to introduce the saddle tank, and all future Allon models will be fitted with a very smart double tank, saddled over the sloping top tube. A U-shaped pipe connects the two compartments at the rear. A sump and filter over the petrol tap is a good feature, while the capacity is one and a half gallons of fuel and three pints of oil.
Efficient metal leg shields are now a standard fitting, also small aluminium covers over the front and rear hub band brakes.
A coil spring hidden in the magneto contact breaker cover enables the former vertical spring and cable stop to be dispensed with, and so gives better access to the sparking plug.
A Severe Test.
The model illustrated is a special order, and, although the makers do not intend this lightweight for use with a sidecar, it is quite capable of giving much good service within reasonable limits.
The Canoelet-minor sidecar as fitted is probably one of the lightest attachments obtainable, but it cannot be termed roomy, and is only suitable for a small person. Nevertheless, a run of several miles in Birmingham traffic, and incidentally over tramlines and cobble paving in an atrocious condition, served to show its capabilities ; although rider and passenger were each about 11 stone, the second speed was very seldom needed.
Rally wheel covers are specially fitted to this machine, but these are not standard.
A lady's model also incorporates the saddle tank, and a belt guard.
The firm's recently patented sidecar lugs are now being made, and give promise of being an excellent fitting. The ease with which they can be manipulated will be the chief advantage; the possibility of detaching or attaching a sidecar by hand, without tools, is certain to appeal to sidecar owners.
