I did a search but there is nothing specific about what I am trying to find out.

So I bought one today. The "Gas" Version. :roll: Well, I installed it according to the directions, cranked the motor up, hit the throttle and had a Max RPM of 5000. :o This little motor is supposed to have max RPM of 3600. It also says it's idle is 2300. These numbers sound high. Don't they?

The model I have is the one where you change the settings for spark. Could this be set wrong? Doesn't a gas engine have a spark every other rev? 1 for combustion 1 for ingnition. That means it would be set on 720 not 360 right?

I'm stumped.

Intake, compression, combustion (power), exhaust. Single cylinder fires every other revolution. V-twin fires every revolution opposite cylinder each time. As for the setting, I'm not sure.

Woops said the wrong thing. Should it be set at 180 instead of 360?

Maybe it's right, but 5k rpms sounds a bit high.

Thanks for the help Kibb

doubt if that is right. think there is a setting for number of cylinders and you probably need to adjust that...

Still having issues with this tiny tach. If I set it up to read the idle RPMs right, which are 1000-1100 RPM, at WoT out of the water, I only get 2300-2400 RPMs. MAx for this 6.5 is 3850+/-150 RPM.

According to this page, it is to be set at 720, but then the RPM at idle is 2400ish. Right now I have is set at 180 and the idle speed is right, but this setup is for 2 sparks per revolution.
Doesn't make any sense.

OK, talked with the Tiny Tach tech and he said add more wraps and I did. Here is what I have. What do I have wrong?

I just wrapped mine around one of my plug wires like you have done and it works great.
