Tii 4mm Tool Clarification.

[PaulTWinterton]

Just so I'm clear.

I've been told, read, and seen DIY mechanics using a 4mm rod or drillbit to set the TunaCan cam to benchmark the KF fuel/air. The cam resting up against the edge of the 4mm rod/drillbit.

Now I've seen the best picture of an ACTUAL 4mm BMW tool. Is it possible that I've been setting up my KF wrong?

During setup should the cam rest against the 1 or 2 position on the tool as shown below? If it is #2 then what is that diameter?

Thanks,

Cam rests against #1 position. So 4mm rod works just as well.

Proper tool will bottom out in indexing hole before larger radius section can contact the cam.

That's enough clarification for me.

Paul,

Here are the dimensions of the original BMW tool, out of the Kugelfischer maintenance manual

Here is the picture of the original 4mm tools, three generations on top, a reproduction, and a 4mm dowel pin that does the exact same thing because the 4mm is the only dimension that matters in this tool.

You can grab an allen wrench

Or use a proper tool

The factory setting should be used as a starting point. On engines like mine, your adjustments may be totally different.

Jim,

Did you ever check how your engine was running with the the throttle completely closed? Was there an airleak thru the warm up regulator hose? Or is the throttle not fully closed?

Two DIY tools for adjusting the KF. I hope it helps.

La verdad, era un destornillador viejo de mi padre al que le corté el mango para otros usos. Con lo que quedó hice la herramienta.

Me alegra ver una respuesta en castellano. Gracias. Saludos: Pepe (España)

To be honest, it was an old screwdriver of my father. I cut the handle for certain aplication. Then I took the handicaped screwdriver to make the KF tool.

Good to see some words in my mother tongue. Thanks. Pepe, Spain.

I never got that far. It has been running fine ever since the last round of adjustments.
