All that and no difference, did notice at 5000 revs when I done a mag check the engine didn’t like it , both the same , pulled the plugs and were all very black , swapped them with new ones about to try again and thought maybe check the air filter which is mounted in the bottom cowl , easy to overlook, caked solid and beyond cleaning as it would fall to bits, after much driving found found a good enough replacement at the fendt dealer , fingers crossed will fly again tonight, looks like I may overthought the problem again.
