Hi I just recently purchased a airplane with 2 OS wankel engines but can not seem to get them to run properly. When I fuel up the airplane they start leaking out of the carbs and wont run.....just sputter. I have checked the plugs and even replaced one with a 4 stroke plug hopeing this would help. Are the engines suppose to be carb up or can they be installled at a 45 degree angle like on the picture? Also any help with the needle valve adjustment setting on the low end or high speed would be great. The engines did not come with a manual so I had tried about every possible setting but they just seem to blow the fuel out of the carbs while trying to run. I leaned them out with the high and low needles but it still didnt seem to help much. Thanks and any help would be appreciated.
