Default RE: DL55 or EVO58

True Ari, Too many on this forum repeat what they read or hear. Those who know this engine have quite different opinions.
Here are the results of comparing the wt201 with WT610 carb. The 201 main jet is 0.88mm, and clearly too small for good adjustments. DA50 users reported the samelimitations with this WT201 carb.
The CHT (Cylinder head temperatures)readings are with same prop, just main jet adjustments were made. Final picture, the engine still was nicely two-stroking on a large prop, but CHT was down to safe levels on my test stand. In flight needs leaner settings due to engine unloading.
