At the bottom of the kickstarter, where it goes through the 90 degree / wedge part. At the bottom, there are grooves cut for a detent to index the lever (deployed vs. stowed).

Is that a pin and spring? I have nothing there......

You're missing this special spring washer -it's like a flat spiral going through about 720 degrees (I forget what they are called), and a special washer with a depression pressed in it that mates with the grooves in base of the black housing, (scuse fingers!) -it also has little tabs on the inside diameter that slide into those grooves in the base of the main lever.
When it's all bolted up causes the 'detent' to hold the lever in / out when it rotates.
(Hard to describe really!). Assembly as follows: slide the housing onto the main lever, followed by the 'detent washer' so that the indents in the washer fit into the corresponding depressions in the housing, and the little tabs slide into the slot, then the spring washer, then a plain washer and bolt.
Gawd it sounds all a bit long-winded eh?! Make sense?

It has been awhile since I was into the kickstart on my Venom, but I don't remember any of those bits! Was there a design change between the early MACs and the Venom?

Yes Ed, these were used only on the old ones (Pre 1946 I think)
Sorry I can't help with a source, but part numbers are as follows:

A278 -"Clickwasher for swivelling footstarter crank"
A254/2 -"Springwasher for swivelling footstarter crank"

I'd be surprised if you couldn't track down a suitable springwasher at good fasteners outlet, size is: I.D. 5/8", O.D. 1", Approx 3/8" thick uncompressed
And it wouldn't be too hard to fabricate the clickwasher.

Thanks J: mine bike is a a1952 rigid MAC. Its the older style gearbox. I just made a "click washer". 1" od washer, drilled the center to 5/8? ground a piece of welding rod to a "D" sections. Laid is across and welded it in, then took out a little center piece. works fine. Still no washer. I'm going to cut a piece of 5/8 heater hose (heavier wall than garden hose), and let that be my spring. should work fine....
Mike

now that I have it together........something doesn't look right. It pretty much is the only way that it goes together, all the pieces that came out went back in!

Seems that I've seen MACS with the same gearbox; with the kicker up, pointing at 11, 12 and over the top at 1 o'clock. What gives?

Mine looks like the nut for the pin hits the stop at the top of the ramp. Can this be right?

Or will it stop in a different position , when installed on the gearbox?

Can you put the pin in from the other side so that the nut is on the backside?

no. holes are different sizes. I looked at my "before" picts, and its in the same place as before disassembly. I've looked at other same vintage MACs. the kick start mechanism changes....but the ones that "look" like mine, clock in a multitude of different positions.......

Is the pin an off the shelf cotter, something made by Velo, or something home made? I am wondering if you can either get a pin with a smaller diameter threaded portion or make a nut with a smaller hex? By the way is the nut fully home?

Looks like the cotter pin is too long - shouldn't be that amount of thread above the nut.

The housing ramp may be worn, resulting in contact with the cotter nut.
But that would affect the kickstart engagement too, you'd need to assemble it on the 'box to check it.
A thinner nut and washer would help obviously.

I am officially a "dope". holes were the same size, I just put the cotter in from the wrong side. All is right with the world. Ed had it right!

Down on the kicker, the gear moves out......lever up, the ramp pulls the gear in. 5/8 rubber spring works pretty well.
