100cc Super 1050 automatic

Picked this sweet little saw up off Ebay, needs some attention to the starter pawls and plug wire.

I'm not sure what would fit that thing .Maybe the starter pawls from a c5 or c7 .Scott in Vermont may be able to help you out or Bryce S .aka cheap chainsaw parts on flea bay .

When I get some time I'll take a peek in the big Homey book of IPL's and try to get a part number .

Thank you for the information and I have found that a lot of Homelite chainsaws used the same starter pawls, I stole a pair off of a old XL-800 flywheel. I repaired the stripped threads with Loctite and a helicoil but now I am having trouble finding the correct size shoulder bolts to attach the pawls.

The bar and chain showed up yesterday, the chain was kind of a surprise because the auction ad did not mention it and it was not in any of the pictures.

Here is a little redneck ingenuity for ya.....

The flywheel is fixed, had to end up making the shoulder bolts. I ended up installing helicoils in both holes because even the "good" side seemed to hold the bolt a little loose.

I have no clue what the little threaded sleeves are called but they sure did save me today, those are 1/4x20x1/2" bolts.


I cut part of the sleeve off and threaded it onto the bolt to create the shoulder, I used red loctite to hold the two parts together.


Here is the flywheel put together, I also used red loctite to hold the bolts into the helicoils.


I stopped by Lowes and picked up a nice D handle to help pull the 1050 over, compression test shows 180psi.

If I'm not mistaken those things are called flange nuts .They use them to hold wire reels together among other things .


Those grade 2 bolts will work but I'd suggest you check them periodically because they aren't  case hardened like a grade 8 shoulder bolt .

Now if it takes a 1/4 20 threads chances are it's a 5/16" shoulder .Fact is coincidently as I type I have one in my pocket .For that matter if I knew the shoulder length I probabley have several dozen some where hiding in a coffee can .

Now that you mention it I do believe the box was marked flange nuts. They have the type I bought and another that had spikes around the flange area, I have seen them used in the cheap pressed wood furniture you can buy at Wal-Mart.

Finding 1/4x20 shoulder bolts was not a problem, finding them with a short enough shoulder is where the problem was. The shoulder only needed to be long enough to barely clear the tickness of the starter pawl, maybe a 1/8 - 1/4 inch at best. Only ones I could find had a good 1/2 inch shoulder.   

I did mean to grab better grade bolts and did not realize my mistake until I was already at the house, so I will make sure to check them from time to time. I also bought a parts saw off Ebay this morning that is coming with a good flywheel, so I will have a back up now.  bought a parts saw off Ebay this morning that is coming with a good flywheel, so I will have a back up now.

Got the 1050 put together today and it started with 6-8 pulls, but I believe it needs some carb tuning. It will run fine at WOT but falls on it's face when it drops to idle. Had to find a plug boot cause it bit me a couple times, but I did figure out that it seems your hand makes a adequate kill switch.
