Default How sensitive is the magnet sensor position?

Just wondering how sensitive the magnetic sensor is on the Super 80? I know it is supposed to be 6mm center to center, but wondering if anybody has had to adjust it after running it in? Thanks!

Curious what issue are you having to ask the question. I just posted a question on Mid-range issues and was wondering about changing my timing a bit....

I'm surprised you haven't gotten anything further here. PM Dick Hanson on here with the question. Since he does a lot of work with headers and pipes on the ZDZs, the 80 being one of em, I'm sure he has done plenty of experimentation with adjusting the timing, and can give you good information to work with here. Please do post any feedback you get.

I've owned two ZDZ engines, a 60cc and now a Super 80, and I have always set the timing to the manufactures recomendation. The settings have always worked just fine, but I have always used a Pitts muffler and a two blade propeller. The thought of changing the timing was not even considered then, but I recently changed to a canister muffler and a 3 blade propeller, and I'm experiencing some mid-range issues. ie the reason for considering the timing change a an experiement prior to making any changes to the header.. ie my posted question to mike.

I got a reply from Mike at RCS

Patrick,

With the TR-80, you MUST use the wraparound header at its full length. DO NOT SHORTEN IT.

We use this setup with the 26x12 2 blade and get 6400rpm.

The 24x12 should be close.

The silencer must be getting cooled sufficiently to work properly as well.

Please look at tell me what carb is installed on the engine.

I hope it is a Walbro WJ71.

Let me know.

Thanks,



Mike Dooley
