Title: Villiers 9e carb fitting prob.
Post by: Bob Purton on November 29, 2012, 05:24:59 PM
Hummm... just went to fit the carb on my rebuilt 9e and it wont go on, I know the bowl goes in that recess cast into the casing but I cant drop the bowl into that and get the neck onto the inlet manifold at the same time. Is there a technique? Do you have to fit the manifold to the carb first and then manifold onto the engine? What a performance!

I believe there are two types of inlet manifold for the 9E. One straight and other is angled to help clearance.

Thanks Rob, that could be it. I just remembered I used a barrel and manifold from an 11e so maybe its the wrong type manifold.

I've just googled this, Bob ... http://www.users.globalnet.co.uk/~pattle/nacc/arc0596.htm  

In 1955 the Mark 9E engine was offered.  This had a smoother outer appearance and was used as a pattern for future developments.  It was made available in either sports or trials trim, the trials model having a heavier flywheel to give smoother torque at low speeds.  A compression ratio of 8.25:1 was used, a caged roller bearing big end with 9 steel rollers and a special ignition coil with a cam which gave a longer dwell in the closing of the contact breaker points.  Trials engines were fitted with a gearbox giving wide ratios and the sports, or scrambles engine standard ones.  A number of different specifications were offered for kart engines and a standard model fitted with turbo cooling fan and a choice of either kickstart or electric start for use in scooters was also available.  The electric starter used in Villiers engines was the Siba Dynastart which used a 12 volt system.  The reverse mechanism used the fact that a two stroke engine runs just as efficiently in reverse as forward and fitted a switch which stopped the engine and then restarted it in reverse.  Engines fitted with electric starter, fan cooling and reverse gears are noted by the additions of S, F and R after the Mark coding e.g. 9E/3SFR is a 9E engine fitted with a 3 speed gear, a starter, fan cooling and reverse gear.

The 10E, which had a cylinder in an upright position and the 11E, which was a slimmer version for use in scooters were both introduced in the latter years of the decade.  The 9E was produced until 1967, the last year of Villiers as an independent company.  It had certainly been a success.

Ooo! Your name has come up in a lovely shade of blue.  ;D

Yeah, other one is called swan neck if I'm right?

So a straight one and one for Queens. Sounds about right. Nice.

it all sounds sensible advice - good stuff there rob. but is it that simple ? just had a quick peak at my 11E and even that manifold has a kink. yes i have seen the ones with a more obvious "swans neck" but what would happen to carburettor function if i turned my manifold upside down ? as it is the 11E has the well in the crankcase and the angle actually makes it harder if anything to fit the carb. could you turn the manifold over bob ? just a thought - or would the carb not then be horizontal

pics - poor i am afraid of my 11E

Bob, If you have a straight one and not a droopy one like Richard has, I'm sure it will help in your clearance and will do the trick.  Aunt Doris.  ;D ;D

Having just returned from a nightmare journey to Putney today to collect a pair of library globes I finally got a chance to whip the engine out of the car again and tackle the carb fitting problem. I don't know if mine is droopy like Dickie's ones but can confirm that if you remove the manifold, attach the carb and then refit, it all fits in place. See pic.

Ah yes, it sticks out straight and true like a good'un should.  ;D

i do think its droopy like mine perhaps you could put one of those tablets in the fuel . it looks very nice but whatever would that be in the background bob - is this it's first public airing  ;)

Guess, pic taken near whatever pier it is that people fall off hoping to win a prize for flying a 100 metres or some such distance?

As Fred Dibnah used to say on seeing an engine, "Does it run"?

It's a photo taken at one of the London Marathons I believe. I wonder if the chap jumped off one of the bridges on route when crossing the Thames?

Havnt tried as yet, still waiting to hook up an exhaust so as not to deafen the folk next door. The dynastart turns it so that a good sign!

Just decided to test the dydnastart on my newly rebuilt 9e. I had the instructions for connecting up the cables to a battery with the engine on the bench from my Schmitt days but could I find them? No! Then remembered Big Al mentioning them on the forum. Connected the engine up to my Punto  with jump leads and much to my delight the dynastart works fine in both directions. Now I'm wondering, should I have sourced a cylinder head with a decompressor? Then again scootacars dont have one neither do Friskies as I recall. Is it only Bonds that have them?

I am up north again so have no info with me. But its possible isn't it that bonds only used them on the pre dynastart engines . Took the strain off the hand pull start then the starter motors though I am not at all sure. Some of the villiers motorcycles had them as  an option but I again I don't think the dynastart scooters did have them did they ?

A 9E with its original 197cc top end won't require a decompressor.  The 31a & 35a used in Bond MkF & G with a 250 top end
needs the decompressor as the dynastart does not have the capacity to spin them  over.
Similarly a Sachs 200 with a Saab piston could do with one as well  :o

My bond mk a has a 122cc villiers 10d engine with decompressor which you would hardly think it needed n but its the early pullstart pivoted down from the fragile dashboard  I suppose it makes it much easier on the car body

Ok, I will forget the decompressor idea. It only came into my mind as my last Bond MkC did have a 250cc conversion with decompressor. Thanks for the info Grant.
