If you pull the plug out and it pulls easy but put it back and it is too hard to pull makes me believe that it is flooded. Either too much fuel built up or you put too much ARO in it and thats why its hard to pull with plug in it. Take the plug out again this time turn engine upside down and pull cord for several seconds to clear it out. Replace plug and try again.

Also preheat the engine with a hair dryer see if it helps.

Maybee I did use to much after run oil that would make sense.cause it runs great.i just didnt like the fact I had to get a new pull cord cause I broke the first one and its hard to pull.

When I aro my engines I always use xtra but I take my plug out and basically flush my engine out with aro and remove the excess,nitro fuel will atract moisture so the goal in my mind is to remove the residuel fuel and replace with the aro,I run the fuel out of the engine first before I do this
