Are we to assume that it has Villiers 125cc or 150cc Lightweight engine ? The set up is more or less the same for both and there’s plenty on of info line.

Can’t help with the disc but I was fairly familiar with the Trantor. Another good idea that didn’t quite make it. You may know that there’s still a couple or more around in the UK that turn up at shows etc .

Uninformed guess ! The unit’s pulley is slightly out of line with the one driving it. Try a straight edge across the unit’s pulley and see how it lines up with the one driving it.

Mk 25 – maybe ?

Mine arrived today. Cover photo, what is it – can’t find any reference to it ?

Aspera were Tecumseh made under licence in Italy . Latterly called Tecnamotor a corroboration with Fiat.

I’ve got BS parts manuals going back to the 1970s but will need the complete Model, Type and Code numbers from the engines . Theres no short cuts !!

If the shaft is pitted etc you can use a repair sleeve to give the new seal a smooth surface to run on. SKF Speedi Sleave is one brand.

Kohlers , as well!

Not sure where this is going but it should be accepted that back lapping is to keep the edge on cylinders that have been properly ground. Not the process to use to recover really blunt blades.

Definitely suggests an issue with the distributor. Either the cap or the rotor arm, probably the cap.

To back lap properly use a water based paste , not oil based as in valve grinding paste. Water based so that when done you can hose it off and get rid of every trace before rotating the cylinders in the cutting direction. Leaving a trace of paste “ undoes” some of the sharpening effect gained by the back lap. In an ideal world neglected cyl…[Read more]

Back in the day when the Vanguard was currently fitted to the equipment that we were selling we would experience the very occasional strange ignition issues – not starting, running on one and even not turning off on one. I remember that these issues were the subject of one or more BS service bulletins and were usually sorted by the replacement of…[Read more]

I presume that you have the chain off the machine ? So just take it to a bearing and transmission factor who will measure it up and supply the correct link. Possibly the chain is worn and it may be the time to renew it.

I’ve successfully repaired many tanks over the years using a heavy duty Rawlplug electric iron – no naked flame. Alternatively a large old style iron that can be heated with a blow torch well away from site.
I think that your main issue may be other areas that have not broken through yet but are lurking waiting to do so. Anyway, assuming that t…[Read more]

Only ever seen Beta in canal boats !

Re David Bliss’s post regarding Homelite two stroke generators. There’s a James Condon with a YouTube channel where he repairs and restores generators. He recently tackled a Homelite two stroke, possibly of WW2 vintage, with the same style of fuel lift pump that David shows in his post. The lift pump was in rather a sorry state but James man…[Read more]

We seem to have forgotten Lister and Petter !

Without too much head scratching. Loncin, Olsen and Rice, Lauson ,Subaru. In the USA there are several of what are loosely referred to as Honda Clones – several basic engines with different brand names and different colours, such as Predator which is the house brand of the Harbor Freight chain of stores similar to Machine Mart over here.
