My ofna ultra lx2's engine has been sitting there for almost a month now.

when i tried to pull it, its very sticky. and it has no fuel in it, so can't be flooded.
also after i pull it out, its kinda sticky for the return spring to pull the line back into the puller housing aswell.
 
If you didnt use after run oil or WD-40 then you have some old fuel gummed up inside the engine, spray some WD down in the plug hole and pull slowly, if that doesn't help you will probably have to tear the engine down and clean it, Also take off the pull start and clean the OWB (one way bearing) in some denatured alcohol,that's why your pull start feels sticky,it wont need re oiling as it gets that from the oil in the fuel. Hope this helps.

The thing is if you unscrew the glow plug, it became really easy to pull..

and its a fairly new engine, about half a gallon so far, maybe just need to be break in a little more?

i do use after run oil
 
Yeah, its tuff because its cold, I had the same problam on my Revo, but after she turned over from many tuff tugs, she pulled like a fart in the wind lol.
 
take pluge out spray wd in and put some in the carb ,pull about ten times ,ya it will be easy to pull then put pluge in .by leaveing the plug out you take stress off the motor and work in the wd it helps break down any gummed up stuff. it works i have done it on motors that sat for over a year .
