100cc Villiers

Was getting my bikes out for the upcoming move. This bike hasnt seen the light of day for years. Thought I take a few pics. The build is basically finished, just a million little details. The Villiers is driving thru the bottom bracket directly to a clutch on the right side to a 3sp IGH.
I did something I have wanted to do but have never done, is to convert a coaster wheel to a front brake. Notice also where the rear brakes are. Should be a cool old school ride. Its a true 100cc. The old Villiers are smooth, torquey runners that dont rev overly high. The engine is an early 30s and the frame is a 36 Cleveland Welding step thru.This one may reach forty. Will be badly under braked at that speed, will keep it as an easy going 30ish cruiser.

So have finally worked thru all the half finished motorized projects, this is the last one. It was roughed out a few years back then left idle while other stuff was built and left half finished. A bad habit I have, getting the construction done,
then starting something else from ideas rattling around in my head.
I am reacquainting myself with my thinking on a lot of this.

Its actually a 98cc English Villiers engine. Dont know its age, I had the folks in England date it when I bought parts, but of course lost the info. Its just old. It does run fairly well for the brief times I have run it.
Bear in mind its all just thrown together now, hardware is junk holding it all together
The frame is a Cleveland Welding, prewar. Was told was a late 30s.
Front wheel is a rear, converted coaster brake to hand brake. Drive is thru the BB to a jackshaft mounted clutch to a Nexus three speed hub, rear stand is scratch built, and sturdy as its a heavy bike,

Refer to the threads beginning for assembled pics. Some up close details.

The chain guards are mounted to the foot boards and come off with a bolt or two removal with them. The clutch cover is a reworked salad bowl. There is a generator. Exhaust is reworked CG. Fuel tank is soldered together quart paint cans, sitting on a way HD removable bracket. All mounting tabs are welded. Has axle adjusters common to prewar bikes, I really like em! I drilled the holes in the rear sprocket what a pain!

Awesome bike.., the custom fabrication is too cool.

This is the strangest carb I have seen and I have seen just about everything out there,
Is brass, weighs about 2lbs. The float system is crazy, no needle, just a float and a fulcrum arm that
presses against a wide open hole. The main jet tube has an air jet screwed into it. The jet assembly drops thru the carb body into the float area.and is kept in place by the bowl and nut. The slide is made up out of multiple parts.
There is no idle formal idle adjustment. Looks like its fixed by a bypass trough under the needle. I would be temped
to try it except Im 100% sure its missing a spacer under the jet tube assembly, which totally makes it a non runner.

So the intake measures 22mm as does a vm18 I have. Think it will go that way. Really wanted to run the original carb, but not looking for a rabbit hole that deep!

That's definitely a odd looking duck!!! I thought you had mentioned you had your Villiers up & running. That engine sure is cool thou. I think there is still support for that stock/original carburetor. Does yours appear to be like this pic?

I have popped it off squirting fuel into the carb, and it ran pretty well for what that is. I bought it on line, mainly because
there was a vid of it running. Guarantee it was not on this carb. Closer examination revealed it does have a needle seat, just no needle.

A vm18 it is. Its like me at my age showing up with a 25year old hanging on my arm at a party

Now it looks like you'll have to antique the carb or renew the cylinder.

 

[Cannonball3]

Think I will run as is initially to get the usual build bugs sorted. I have become more confident I can revive the old carb.
Now I need to find my parts source in England for some basic carb parts.

The old timer was introduced to the younger hottie carb and after a ”a few drinks together” he got fired up and showed her despite his age he is a smooth operator. Not hard to get started either.

Thanks DT that helps a lot!
