Husky 55 intake repair

[David Young]

This may be child's play for a lot of you. I work with the h 50/51/55 often because there are so many around here well known Achilles heel is the plastic intake bulk head. I think the worst part is the carb is held on by screws that secure in plastics.

Here are some pics of what I do. And a couple 1 minute vids. Hope someone find this useful.

Below first pic is the stuff I use

Second pic you can see the threads are starting to pull out

Good thread David. We have fixed several by using Stihl carb studs. Drill thru, and install from the back.

I usually install a 5mm helicoil and then use 5mm x either 55 or 60mm allen head screws. It works for me

Thanks guys, I like this type of repair I am sure you all have them for various models. Hope it helps someone.

Yep thats what I use. M5, I thought they were 45mm but I will check the length for reference when I get home. I bought them at Fastenal because they were super cheap.

I need to get another pack of Heli coils.

If you do the repair Randy talked about put a dab of loctite on the nuts I had a buddy crunch a new meteor piston when the nut went down the intake.


@Mastermind

Randy when do you want stuff in the technical area and when in the chainsaw area?

You guys use your own judgement on that David.

I'm just a member here too my friend. Think of me as traffic cop/peacekeeper.

Some poulans have similar intake manifolds 4620 comes to mind,The poulans already have metal threads.

I'll have to look in my stash but, I picked up a package of machine thread inserts intended for soft material (plastic or wood) at a machine design show.
