ryobi weedeater help please

I'm working on a ryobi weedeater and need some help with starter,please.
It pulls erratically and i'm not sure that is the right word. When you pull the starter rope it is very jerky and eventually after some cussing it will start and run fine. i've pulled the engine and oiled the pawls which seem fine but nothing seems to work. Ideas?

What happens if you take the spark plug out and pull the cord? Is it smoother?

I don't think so. (but I'm not a pro) It is jerky because two stroke motors have very high compression. Has it always done this? I feel like there is fuel (or some other liquid) getting into the cylinder when it is sitting around making it hard to pull. After jerking on it a few times it will clear out and start. Maybe pull the plug, pull it a few times to clear it out, put it back and try it again.

If you run it a while and shut it down, will it start smoothly again?

BTW - Whats the model #?

I'm not sure about model number. Picked this up at a yard sale and trying to give it to somebody that needs one, but I put all new fuel lines,rebuilt carb etc and then I found this. I have the engine off the unit and I can turn flywheel by and don't feel any "jerkyness" but i hear something like a loose whatever in the cylinder. I'll try some PB in the cylinder and see what happens, Ironhand.

Something loose doesn't sound good.

Most cases you will find the model on the plastic cover where the pull cord is.

I have a Ryobi 725r string trimmer that broke a clutch spring. Made some noise. Maybe that is the same thing?

Sorry for the lateness.

This is a string trimmer right? I saw weedeater and I guess I assumed.

If you do have something in the cylinder it should be able to come out the spark plug hole or you could at least see it.

yes, it's a string trimmer. What I think I found is that it may be the nature of the beast,but I think the rod needle bearing may be the problem. It's "wobbling" a little and it's making the pull jerky, it that makes any sense. I put some regular motor oil on it and it made it better.At least enough to make it usable.
Thanx for your help, Ironhand.

Good! I'm glad you figured it out.
I don't know if I was any help though.
