The heads on mine basically are out in the open.
Do you have pics? I'd like to get a better idea on how you did it.Mine is baffled-on an EF78 Extra 300. It really didn't run consistently and was a booger to jet until I did baffle it. Cylinders also run evenly after baffling. Just directed flow from the inlets of the cowl over the fins. Have a deflector in front of the opening on the bottom of the cowl.
I am running the stihl ultra in mine as per vv recommendations. I doubt the oil is causing a problem.
I will take some photos and post them here. You want baffles and exits? I did a bunch of different trials on exits using telemetry to find the most effective setup.Do you have pics? I'd like to get a better idea on how you did it.
What does your air exit look like? I also found that the scale carb hole below the output shaft made a huge difference in cooling. Blocking that off made about a 20 degree difference. Not that all cases would perfom that way, but it allowed too much air not doing any cooling to use up the exit hole area in my particluar case (no change in jetting). FWIW.I am running the stihl ultra in mine as per vv recommendations. I doubt the oil is causing a problem.
