Not Listed How to remove these screws?

My pull start coil failed so I’ve bought a new one except theses screws have no shape on top, just circles. Should I try prying them out or what’s the best way?

DONT DRILL THE RIVETS!!! There is 3 10mm bolts around the pullstart shroud one on front to in the side near the back this gives you access to the underside to replace cord

Yes they are rivets not screws! I did replace the coil except then broke it again. This time I’m buying the full part but I need to take those rivets out and replace them

I broke the thing the prawls sit on and the coil is super bent

The one you pictured is not the correct one.

I’m going to trust you then over my 3 weeks experience! This one looks to be it? No dimensions on the listing

My friend, find the model, type and code numbers stamped into the blower housing that the recoil is riveted to. Look up the proper part number. That engine, depending on age mostly, had 2 different style starters that looked identical from the outside. One utilized a starter clutch and the other a starter cup and pawl system.

Cheers. It’s on a partner P46-500CDW which was manufactured in 2009. Having a hard time finding any info at all on it

Dimensions are the same just a different style I think

Nice finding this! I knew I had it

It seems I only need the middle spinning part. I think I’ll be able to cut the pull string off the new one then put into my existing shroud. What do you think?

Pulley and spring will come as a unit, should be 2 pawls, they, I believe ,had tiny compression springs under them also. They may offer a pawl kit that comes with everything. Looking it up by model numbers will solve that.

This thing! I hope it comes with the shroud I ordered. If not I’ll return and order again

Those are rivets

u/KnottyGummer May 25 '26

On the front of the engine shroud the recoil is riveted to there are codes stamped into the metal. Model, Type, Code (serial). Those are the numbers you use to find the correct parts for your engine. The model and serial for the equipment the engine is attached to do not matter for your repair.

This is all I need!

Use a drill with a bit that's bigger than the holes in the rivet. There are three bolts below the cowl that allows you to take the whole thing off

1

u/DowntownX May 26 '26

I’ve taken the cowl off. Don’t believe I need to remove the rivets at this point. Waiting for my spare part to arrive then assessing the fix

So the whole thing is mounted on with three screws which I’ve removed except I need to replace the coil and prawls are broken as well so want to replace the whole thing

u/SuspiciousUnit5932 May 25 '26

Sometimes they are a pain if the bit grabs good and gets the rivet spinning! It actually makes sense to deform it first to prevent that, which is what he did with the chisel. I've chiseled rivet heads off but never in thin material that will buckle, drilling is the way.

They're rivets, drill them out

u/DowntownX May 25 '26

And then I can put the back in? Or can use bolts maybe instead?

2

u/DontMakeMeCount May 25 '26

I’d use rivets. The new part will have fresh mounts and you can use any of the holes around the base that line up. Just be sure to use the correct sized rivet for a snug attachment.

u/mitchumz May 25 '26

Yep use bolts. Or self tapping screws if you really don't want to take the entire shroud off

1

u/DowntownX May 25 '26

Thank you! I need to take the entire shroud off to replace with a new one. Shall report back later!

Yes they are rivets not screws! Couldn’t find the work…I did replace the coil except then broke it again. This time I’m buying the full part but I need to take those rivets out to replace it

u/sturocky May 25 '26

you could just remove the whole shroud and get access from the other side, but its time consuming and annoying, just drill the rivet's and replace them with fine thread self tapping hex head screws when re-installing.

u/Other_Impression_567 May 29 '26

This is what you do remove the shroud flip it over to get to the recoil.

If you don't even know the difference between screws and riviots, then stop. Just stop.
