Had an Evo .46...flew the plane three dozen times and had around a dozen dead stick landings [:'(]. Engine would cut out after 5 or 6 minutes. Nobody in our club could figure it out. In Evo's defense, the thing did hand start on the first flip.
Heres a few things to try
check the oring under the carb and reseat
replace the clear line from the highspeed needle to the carb
use a new enya #3 plug they like hot plugs
remove the baffle from the muffler
15% omega fuel
my evo was on the stuburn side till I made these changes
