Same here,but the real test is when you put her in some wood.I bet it'll be fun to watch the chips fly! This post was made with all due respect to all members involved.

Thanks guys!
I went a tested it out on some logs I have around, it really cuts great!
The recoil does seem to not want to "catch" at times. Thinking I should clean it up good, any other ideas?

I think that the starter is the overrunning type, undee are you sure there are dogs in this one? Does not look like the Fairbanks-Morse unit to me.

I’m not really familiar with the technical terms of some of these parts but I was assuming the dogs and the prawls were the same. Prawls is a term I only know from here, dogs are what I’ve always assumed were the two pieces that “sling” out when pulling the rope to catch the drum to turn the motor. Now how’s that for an explanation of how the recoil works...that’s why I felt it was best for someone else to explain that one😂

Yes this is the overrunning type starter, which I understand are a bit temperamental at best.
I looked on the board and couldn't locate anything specifically about repairs.

I think the most important thing for these type starters is that they're clean. Gotta be careful what you use though, I remember one I was cleaning out with either carb cleaner, or maybe it was acetone, anyway the cage was some type of plastic and it almost disintegrated. Now I use brake cleaner to be safe. Heard some people say to use only light oil, some say hydraulic oil, some people say no lube at all. I figure since the bearing is in constant contact with the center race while the engine is running, it needs some type of lube. Don't remember any literature in the shop manuals for the overrunning bearings, but maybe Homelite had something, I mean they used 'em on a bunch of stuff like the 995s, 51/71/91, XP 1000, early 1020, 1100, heck, even the 150 used a type of overrunning bearing for it's starter. I usually put a little moly grease and work it around the rollers. If everything is clean and the race isn't damaged, it'll grab.

I believe that dogs and pawls are similar, at least to me. I posted a thread on a Zip that I worked on filing the dogs in the Fairbanks-Morse starter on that saw. houseofhomelite.proboards.com/thread/3561/brand-new-zip That one had dogs that dig into the metal of the cup when the rope is pulled. Friction in the washers of the F-M starter is critical, do not lube them or certainly it will not work. The ends of the dogs have to be sharp enough to catch on the aluminum of the starter cup too. I think of pawls as the type used on the SXL series, they engage the starter until "centrifugal" force throws them out of engagement as the engine starts. I believe this starter has balls in it that are cammed out to engage the engine as the rope is pulled and they retract when the engine starts. If I am correct that is. Very similar to the overrunning clutch in an automotive starter. At first glance it appears to be a ball bearing, but it only rotates in one direction, allowing the engine to "overrun" the starter pulley as the pulley stops and the engine runs. Leon's IPL shows the two types but does not show the real differences: www.leonschainsawpartsandrepair.com/uploads/3/9/7/9/39792537/homelite_zip_600d_chainsaw_ipl_23794.pdf

When checking the parts book for the C-91 it only shows the starter being the overrunning bearing, no pawls to catch on a cup. The only way to know is remove the starter assembly and then you will know what you need. I do have some of the bearings 58480 if your bearing isn't turning easily. In that case a little grease might help. chainsawlady.

Thanks everybody! I pulled The Recoil off yesterday and the bearing had some pretty crusty looking grease / sawdust mix all over it so I cleaned it up with some brake cleaner and then gave it a light coat of oil, pullled it over about 5 to 6 times (with the switch off) and seems to be working good Saw started within 1 pull so I think all is good
