Hi,
I am a very newbie to this, I had a Kyosho sandmaster st2 back in the days, 25 years ago. I just found it and thought I had it a go to start it.
The whole engine was very thick and oily and couldn't move, so I took it a part and washed it in clean alcohole, now it all turns fine. I have my old fuel where I mix it with nitrogen, I mixed the nitrogen apporximate 15%.
I bought a new glow plug K7 from Kyosho, I read on it that it required 1,5V. My glow starter is 1.2V. The glow plug doesn't turn "organge" by the heat but it does get warm and somes the left over fuel on it if I have it in my hand.

When I pull the motor to start it mostly does nothing, I have tried many times ( 50?) and two times the motor just started for maybe 0.5s and then died again. Can the problem be the old fuel? Or that the glow starter is 1.2V? Or do you have any other sugesstions? Can the plastic tubing from the tank to motor or exhaust to motor be dirty? They also had old fuel in them but they are fine blowing through them now? When my glow starter is in, there shouldnt be any issues with compression right? I will notice compression problems when removing the glow starter?

Thanks
