i just got a caldera and having problems starting it, the starter gets really hard i thought maybe the coil or something inside was messed up but, i took it off and when i pull on the starter/string it works fine, goes in/out and when i had put it back on the engine i was able to pull the starter and it was pulling easily and fine but, then i put all the screws on and after a couple more times of pulling in trying to start it, it got really hard then i took it off again and put it back on and again the first few times i put it on it's pulling fine then all of a sudden it gets really hard. i don't think it's over-primed, i took off the glow plug and turned engine upside down nothing comes out and if it was over-primed it wouldn't pull those few times that easily would it? it's literally 3 or 4 pulls not "few" as in i'm trying to pull it 10 or 20 times and it's getting over-primed.

i noticed when i pull the starter off there is this nut that goes into the engine that the starter fits on, i noticed that that nut gets hard as well, if i keep messing with it, i can turn it with a wrench but, then all of a sudden it will get really hard.

i put a couple drops of fuel into the carb and engine hoping that maybe it'sa lubrication issue but, didn't work same thing is happening. it has only ran once and then this problem started happpening, what could it be? is the engine messed up?
