How Do You Install A New Boot On A 410?

[Deleted]

Back some time ago I made a post about my 410 screaming at full throttle.I was told it needed a new intake boot.I have since purchased that boot,but due to surgery,I had to stop work on the 410.I've got two 410's,one will be my runner,the other is my parts saw.I took the boot out of the parts saw in pieces because I had no idea how to get the plate out that holds the carb & the boot is under that plate.I took the recoil off & the fan housing,that's as far as I've gotten.I'm stumped.

You can do everything from within the carburetor chamber...it's tight, but doable. I know you already have some of this stuff removed, but I'm starting from the beginning for folks down the road doing this repair.

Remove the carburetor cover (has the big aluminum nut with a screwdriver slot) and remove the carburetor. Depending on the year of your saw, the carburetor adapter plate will either be retained with the carburetor screws or there will be a plate held in place with (2) small screws. Remove that plate and you should see the reed valve retainer. It's a black square part with an opening in the center for the intake boot. Remove the (4) screws that hold that retainer in place and you should be able to carefully lift the reed assembly out. Clean all the old boot off and press the new one on.

There's a slight angle to the shape of the boot...if memory serves, you want that to angle out away from the saw. Hopefully someone else who's worked on these saws can confirm or correct that statement.

Reassembly is the reverse.

I would do it if I could.It looks to me like I must get to the screws that hold this plater on from the other side.

There's no screws holding that in place now that the carburetor is removed. It should work loose with some careful screwdriver work. There is a phenolic spacer behind it; I've seen those siliconed in place before even though they don't need to be. It does look like your carburetor pulse hose will need to be replaced as well...can't tell for certain, but it looks deteriorated.

Yeah,this is my parts saw.All the lines in it are bad.I'm doing a practice run on this one to see how t comes apart on my runner saw.On the upper left there's a screw from the other side,that's what's been throwing me off.
    I also read an old post from a bunch of yrs.ago that said that a 410 screaming at full throttle isn't always the boot,or an air leak,it's in the carb itself.There was something about"resetting the carb",then it ran fine.It was on this site too,but I'll be damned if I can find it today,go figure.Since I have the new boot I'll put it on & see what happens.Thanks Leon!

Well,I went out & tried to get that plate off - no dice.Here's a better look:

As you can see in the upper left,there's a screw holding the plate on from the inside.I tried twisting the plate with a pliers,hitting it with a screwdriver & hammer,still nothing.I saw a post over on AS,but no pics available because of the age of the post.The person there said that yuou have to split the 410 in half to do the job.I'm beginning to think that.Was there more than one style of these 410's?

So, Homelite had 2 different plates or adapters. One type (#93306-1) could be removed from the outside after removing the carb. The other type like you have here (#97623-1), required separation of the tank/handle assembly. Two screws retain it from the inside. So, you'll need to remove the 6 retainers that attach the tank/handle to the antivibe buffers and separate the engine from the tank/handle. Move slowly as there are some oil lines that come in for the manual oiler and you'll need to pay attention to where they go and disconnect them.

Can the two plates be interchanged?

Update on the 410 - It seems that I got a little lucky because this saw had the "easy access"intake boot.Removing everything was simple.Installing the boot was fairly easy except when it came to try to put the plate back on.I lost one of the allen bolts somewhere in that stinking saw.I had to disassemble the boot again anyway because someone here told me awhile ago that the boot should tip outward away from the saw,that is not correct.So now what do I do for the missing allen screw?And how in God's name do I get this damn thing back together?It seems that a person needs at least three hands to accomplish anything on these saws.

If the screw fell into the saw you better find it before you go on. If it is in there and you start it up you will certainly do some damage.

I had to take the boot off again to get the screw out.I put the boot back on for the fourth time,but the boot won't come through the plate.Here's a pic,maybe I'm doing something wrong.Is there some kind of special trick you do here to get the plate screws back in too?Like maybe stand on my head when the moon is full on the third Thurs.of the month while singing a favorite song in B flat?

It's been a while since I've done one of these, but I think the boot must be carefully worked through the plate in order to provide a good seal. You'll have to get an edge started through and careful work the rest through using a small blunt object. But you've got to be careful not to tear the boot in the process.

Any update on this? Im looking to replace the boot on my 410
