HUSQVARNA HUSQVARNA THREAD

[Woodwackr]

I have a 455 and a 562xp and never any problems. I just wanted to say that I'm a new member today and I'm very happy so far, someone has already helped me. Other places I can't even get an answer so this is home now. I tore up my shoulder a couple of years ago and had surgery. My surgeon said it's one of the worst he'd ever seen. My 562 XP is just been sitting in the garage lonely. Since my surgeon said no more yanking chainsaws with the right arm I've been looking for a way to get it started with my left. I've been wondering about compression release mods lately and wow the first thing I saw on your site is a simple solution. I've been a machinist all my life and something like this is right up my alley. I just wanted to thank you all so much because a tremendous weight has been taken off my shoulders. Now I can get my saw going and move off grid. Many thanks to all.

Post pics of the project. You ain't the only one who has trouble starting saws…

Okay but I'll have to learn how first.

Wow, yeah that is a safe bet! I was working on a 562xp. The first saw to beat me. Purge bulb would not cycle fuel when hooked up to the carb, but would when connected directly to the fuel line. I replaced the diaphragms in the carb, even used clear nail polish around the seams to block any potential air leaks and nothing, carb still makes a high pitch whistle when using the purge bulb. It was frustrating.

I have a 562 XP and it kind of worries me to hear stories like this. I haven't had mine apart yet even to change a plug so I'm wondering does that have the plastic intake manifold ? You say that it runs hot so if it has the plastic intake maybe it could be slightly warped from the Heat causing an air leak. That's just a wild guess. I work more on motorcycles and cars than chainsaws but they're all basically the same thing. Glorified air pumps. Good luck.

I just had another thought. Maybe the whistle is not coming from the carb but the purge bulb.

It's easy to start a chainsaw with your left arm. That is, in fact, the way I start all my saws. Just watch any "Bucking billy ray" video and you will see how....

I thought about that, replaced the purge bulb and had the same issue. I direct connected the purge bulb circuit to the fuel line (bypassed the carb) and it cycled fuel like a champ. I put the carb back in line and it starts whistling and starts sucking air from some where.

Time for a new carb. I've come a across a 555 that did that. The purge bulb would suck 80% of air and only a little bit of fuel. I was thinking the electronic valve was stuck.

That sounds about right...I pulled that off and it appeared that the rest of the carb was moving fuel fine, but with that part being a sealed unit, hard to tell what is going on inside. I may just take it off again and bang on the module to see if something changes. I can't hurt anything, it is broken/not working at this point. I may have to pry it open just to see what is inside.

When you put on your new carb, did you have to take it to the repair shop to get the saw flashed or did it just accept the new carb?

The shop asked the saw’s serial number. I didn’t take the saw to the shop.

That's strange. Now my curiosity is piqued. I'm going to have to take the cover off my saw and start looking at it.

Yeah I've seen that, but I'm in my mid-60s and about half his size. Something that really helps me though is doing dumbbell rows with the same movement as pulling the starter cord. But I'm going to do that compression release mod that someone here told me about.

You sound like me. " Pry it open just to see". Remember that curiosity killed the cat, and Murphy's Law is just waiting to bite you in the behind. Some of my " just to see " adventures don't turn out so well. When you get the thing apart post some pics so I don't have to tear mine apart. Hahahaha.
That may be funny to you but it's actually not a joke. Good luck.
