Hello Folks. I think there is something you should know about this case. The positions of the needles are changed in the factory in Warsaw. We do this due to seeing a bit too high egts in the 4400-4900 RPM range in our climate. Also for this reason, the engine ecu software has been modified for fuel injected versions. There is a possibility that in other places than Poland other setting will be the best and safe but we recommend extreme caution when modifying carburetors adjustments. And we advise against it to people without experience in this matter. Lukas
