Re: DRIVING LICENCE

Hi Jonny; - IF "so i must have been dreaming about riding my square four in the late 60s with a chair on L plates at 16" - I don't think you were dreaming 'cos I was doing similar in v. early 70's... Main problem these days is there's too many cars on the road... mostly Chelsea tractors dr...

Re: Mk1 Sq 4

"Standard" orientation of distributor body on Mk1 was "Flat" was toward rear - approx parallel to front face of the oil tank.
As a matter of interest - I would like to hear of the methodology used to actually strobe the ignition on a Mk1, thanks. John

Re: Experts

Agreed - "Experts" are a dying breed - observe the modern car garage "mechanic" - he or she plugs in a diagnostics - bins the unit as identified as failed - fits a new one at the cost of all three testicles... and claims it's fixed... (not necessarily true!). The last of the Vulc...

Re: Fitting new valves and guides

John W. - love the "6ft long pipe extension" to adjust the head studs - reminds me of using a scaffold pole as a lever to undo the drive sprocket on a Arrow several years back... and recently I sheared an 18" torque wrench whilst attempting to remove a wheel nut form my Ford Focus; - ...

Re: Double adult sidecar

Hi Bernie - I can recommend the "Busmar"; - either the Saloon or the Astral as big roomy chairs... Unfortunately I have no idea where you'd get such a thing nowadays... I s'pose you could get hold of a chassis such as the Watsonian SV4 & custom build your own bodywork! Cheers, J. PS - ...

Re: Cylinder firing order in a square four

Sorry folks - I too failed to appreciate that AKumar was referring to a mag-dyno Sq.
I have no working knowledge of these & speak only of the all ally coil ign. 1949 & later.
My comments abvove are relevant to '49 & later only.
Apologies if I've caused confusion. Cheers, John

Re: Cylinder firing order in a square four

Sure - maybes you can orientate the distibutor body wherever tickles your fancy... Such does not alter the fact that when viewed from above; - the "buisness end" of the rotor arm points to the cylinder which would be sparked. I believe this to be true for both Mk1 & Mk11 coil ign machi...

Re: Square Four mk1, oil pressure

Hi Torbjorn, please are you running the original plunger pump or have you fitted a Morgo?
BTW - the "jury is still out" as to which pipe bore should feed the pressure gauge & which should feed the rockers... as far as I'm concerned your routeing & plumbing is correct...

Re: Clutch Lever still feels heavy.

Hi folks; - here's a lateral suggestion - perhaps try reverse levers - those that pivot at the outer end of the handlebars... they went out of fashion yonks ago but the leverage advantage gained by having your stronger fingers further away from the pivot is considerable. Such will probably be a pain...

Re: Cylinder firing order in a square four

Hey - the pic of the distributor looks suspiciously mislabeled! Sit on the bike - twistgrip hand is front pot #1 - number clockwise from there - thus clutch hand is front pot #4. Pic #1 of the block is correct - Pic #2 is WRONG The rotor duplicates the pot layout - the contact arm points to the resp...
