Brian, I am running my oil mixture as the manual i got with it states.. 25:1
i have been chatting with Scott P. and he said i should be running a different mixture. I use Klotz R50 for oil because i buy it by the case to run in my dirt bikes. It seems to burn well. I have little to no smoke out the pipe and have yet to foul a plug.. it doesn't load up at a stop , idle, and i have also put a cap full of Marvel Mystery Oil in each tank i have run through it. total of two tanks so far. i just filled up for the third time. what do you suggest?
