Well before you try to start it again, take off your pull starter and take out the one-way bearing. dont remove anything else from the pull starter housing cuz it isnt fun to winde the spring up. You can use denatured alchahol or anything thing that can clean oil. I think you can even use nitro fuel but that cost money
. After u clean the one-way bearing assemble the pull starter to the engine and recheck your plug to see if it is "glowing". after that reinstall it and prime till the fuel gets to the carb then once more. Then try to start. If it still doesnt start, hold the throttle open SLIGHTLY. If all of that fails take to your local hobby shop
. I hope this helps. I have the same engine in my t-maxx and the one-way bearing does get dirty sometimes.
