Linkage bushing - Check your local hardware store's supplies of plastic bushings. You'll probably find something that works. It doesn't need to be perfect or exactly like the other at this point.

When I took it all apart, I noticed that there was a spring in the bushing on one side. Will the other side need a spring?

The 2nd bushing was there, it has just pushed into the cup. But it is in bad shape.

Not necessarily. The entire thing operates as a unit, so one spring should be fine as long as it provides enough tension.

Yes, you can adjust that linkage. That's the one good thing about the cross bar linkage. The fact that it has to be done is another opinion.

Great Job!

Love the cacophony of an aircooled motor on carbs!

Linkage is still wacky, but I got it DONE. 1.8 liter out of a 914, converted to a 2.0 liter, with Camper Special Heads, swivel foot adjusters, solid rocker spacers, chromoly push rods, 9550 cam, flamer thrower 3 module and coil, Stock exhaust, dished bus pistons, 7.4 CR for my VW BUS, borrowed weber 40s ( IIRC ) for break-in.

Some may remember my 1911 for my 914.... I screwed that up for sure. Miss-indexed the cam and the crank....

never started, had to crack it open and there is was. That one has 50,000 miles on it now.

Thanks to all that got me this far and thru that mess.

here is the finished product.

@malcolm2 - Those were 44's. Sounds great, very nice grumble to it.

I've seen it with springs on both sides, and single. You are on the right track, getting spacing and geometry the same on both sides.

On a couple 6 conversions, I've had to slot some of the mounting holes on the bracket. and/or bend the brackets to help alignment.

If you have to "cheat" and slide the brackets on the crossbar, do your best to get idle stop position and wide open throttle the same on both sides.

This is where I think the round crossbar type is better, because the linkage arms can be clamped at any position.
