The guy I bought mine off said he was mixing it 20-1 but was adding a little more oil just to be safe. I brought it home and took it for a spin wide open through a field. I stopped and looked back and it looked like a frigging war zone! :ohmy: Smoke was drifting up through the weeds, it looked like the field was on fire. And talk about spooge, there was spooge coming out of everything, head pipe, where the silencer and pipe meet, and out of the silencer too. Since then I drained the gas and mixed it 24-1 and it was still smokey. Now I am at 32-1 and that seems right. Spooge level is way down. Its still running a bit rich but I think most of my smoke now is from the old silencer packing. The stock silencer can't be repacked and I know it is full of spooge. Aside from that 32-1 seems to be working for me.
