SHUDDERS WHEN CLUTCH RELEASED

E.EVERYE.EVERY
Sure could use some help.
Ever since I built my Speedster, every time I release the clutch the whole car shudders pretty bad. Reminds me of the time I tore half the facing off the clutch plate on my 66 Fairlane when I was 17.
When I built the car I measured the thickness of the disc (ok) and presure plate looked like new. I have know idea what kind of cluch it is as this engine was in a dunebuggy. (rebuilt before installing in my Sppeedster).I don't know if the plate has cusion springs or not. The clutch works fine if you are rolling the slightest amount, but if you are on a hill, OH BOY!
Do I have a problem or is this typical of VW drive train. Chassis is a 65.

An incorrect "dip" in the bowden tube may be what you are experiencing. Too little dip will cause a clutch cable shud-d-d-der! The tube should dip down in the middle. The good news, this problem is easily fixed with a few shims. Can't remember the exact spec off hand - something like 3/4 inch dip? Check any VW manual. This is one spec our replicas do NOT modify. And remember to center the clutch cable in the bowden tube exit to prevent chafing.

If it's not the Bowden tube it could possibly be the clutch disc.

If it came out of an "off road" dunebuggy, the original owner could have installed a feramic 3, 4 or 6 puck clutch disc. These are fairly common with the off road crowd as they refuse to slip.

If nothing else solves the problem, you may consider removing the engine and checking the clutch for the correct street components.

Well do I feel stupid or what? I omited the tube when I built my car because to shorten my cable I cut it 3 inches longer than needed then overlapped the two ends 1.5 inches then wraped them with wire and solderd together because I don't trust the ends held on with a set screw and doing so it wouldn't fit in the bowden tube. Sure would like a hydraulic slave setup.
Well I'll be removing the transmision in the spring to install 3.88s so guess I'll be looking at the clutch assy. and the bowden tube and new cable. Thanks much for all the info guys.

Films like The Terminator, where the assembly line robots have taken over?
I remember being at my cousin's house in Grosse Point Woods (a Detroit suburb) one night in 1964 (?)when I heard lots of gunfire just a few miles away. That was the year of race riots. That same year, the hotel room where I interviewed for a job, later had its windows shot out from across the freeway. I left Detroit in 1967.
