Huztle MS361

I am going to put one of those husky screw on deflector kits.

Debugging continues.

Last night it died after a short run and refused to restart. Today I pulled the carb and it was totally dry. It wasn't passing fuel. Reassembled carb and changed the fuel filter just to eliminate that. I did notice the carb fuel spigot was weeping around the hose and pushed it on a tad further.
Maybe it was sucking air.

The carb has a Mylar pump diaphragm. Not my favorite material for that.

Screws supplied for the top wrap handle spring mount were unsuitable. I used a couple smaller leftover from a Farm Boss.

First major failure.

I consider it major because if one were to push the stem in sans button.

The stem would most certainly interfere with the piston and wreck the top end.

I think the same thing was reported in the 660 thread.

Does the decomp port go all the way through the cylinder wall with a large enough hole to fit the valve?

 

[67L36Driver]

.391" tap drill for the threads.
Does that answer your question?

The stem will easily pass into the cylinder.

what we need here is a picture... 360 vice 361 but same idear

 

[Justsaws]

Yep, thanks.

When I did my 272 top end on my Husky 61 I had to cut that button off.. but on that style of cylinder it can't fall in... Perhaps some JB weld on it would keep it on?

 

[67L36Driver]

I'd be more comfortable cross drilling the knob and stem for a tiny roll pin.

Not the first time I've seen the problem.

Fellow came by over a year ago with a MS 441 that swallowed the decomp valve stem (OEM Stihl). Fortunately for him it had passed thru without doing any major damage. Just dinged up the piston crown a bit. Yikes![emoji15]

With the multiple failures we've seen, I wouldn't even install their decomp. You're playing Russian roulette.

 

[scheffa]

Can you simply install a bolt to block it off? Don't think a decomp valve is really needed

 

[blsnelling]

Get the proper plug or use an OEM decomp.

 

[Ryan'smilling]

I'd plug it. I never felt my 361 needed a decomp.

 

[67L36Driver]

The carb on this supposed to be a Walbro HD clone?

It's not passing fuel reliably.

I think it is the hard plastic pump diaphragm. Not flexable enuf.

I'd plug it. I never felt my 361 needed a decomp.

Does Stihl have a plug for that or did you just use s bolt?

Short bolt from the hardware store has a larger hex head. Usually won't clear adjacent cylinder fins.

 

[Ryan'smilling]

There is a product available. I don't know if Stihl makes one or not, but a quick googling found several.

I didn't plug mine because it worked just fine. I just never felt it was needed. I was just saying that if I was in your position, I'd plug it rather than buy an OEM decompression valve.

We are dead in the water. I can't get the carb to pump fuel. Even pulled the end of the impulse line and squirted mix into the crankcase.

Every time I pull the carb off ''tis dry inside. Replaced the original diaphgrm with a brown one, bottom. The original is the middle.

Top one (rubber) don't fit. Locator tit hole (arrows) is in wrong place by a tad
