today i ran the car on my driveway with the air filter off and it was awesome! good punch and top speed. then i put it back on and it felt crappy again. it bogs withe the filter on so i tried to lean the low speed mixture and it dies how should i go about doing the high speed mix. first? find top speed or what?
clean the filter or replace NEVER run a nitro car without a filter
