the "dogs" aren't hard to find., they are the little tabs that engage the pull starter to the flywheel
Yes, it pulls freely when the plug is out and the pulley on it's own when it's off the body.

When a cylinder floods it makes the compression rise dramatically, when the piston nears the top of the stroke[ TDC] it resists going past top dead center, this makes the pulling of the cord feel lumpy as the recoil feels like it is binding up each time the piston nears the TDC.

For those of us who work with saws a lot but are not saw mechanics, these explanations are excellent. Guys like me are all a little smarter after reading this stuff. Thanks, Jerry!
Jerry is spot on here, he simply has a flooding issue. The old "I used some carb cleaner" thing gets a lot of folks into trouble. As most of us know carb cleaner can ruin gaskets and diaphragms. I would suggest completely disassemble the carb clean all the metal parts with cleaner, and then wash it all off with water, dry with compressed air, install a kit. But first read up on how it's done. The search button is your best friend on this site, a huge wealth of info in there. I hope this helps, here's a link to show you how it goes together.

I've bought a few saws now that the owners had given up on, twice in the last month I found the carbs were assembled incorrectly, after putting them back right I had good running saws.
hard to pull, jerkie. strange thing is...i was using the saw before putting it down and switching it off to move the the tree stump and other stuff, went back to it 5 mins latter and bugger me...hard to pull and jerkie...removed spark plug and pulls freely.
I have an 038av super (never any problems with it, brought it as a teenager), this saw has a metal screw with a rubber washer that screws into the side of the cylinder head, is this screw what you guys call a compression release button???
If it is, i'v removed, plugged the spark plug back in and still hard to pull, so much so something is clearly wrong, i can't see how its the rewind starter component as when the spark plug is removed all is sweet (just like it was running 5mins before)
i've downloaded the dealer workshop manual, but don't want to disassemble the head etc to find the issue. because of the nature of it working one minute and not the next i think it must be something basic and common on these models for it not to be know...
cheers for any assistance
