Husqvarna 372 flooding
« on: February 21, 2013, 08:46:44 pm »
Hi everyone, new here, got the link from the Treehouse, thanks!!

3 of my old, everyday-use 372s were stolen a few months ago, they were great saws, no complaints at all, they had amazing longevity as well. So I replaced them with 3 new ones cuz why change a good thing (though I wish I had read the 562 thread before and I would have tried one of them instead).
The new ones cut and handle very well just like the old ones and the fuel economy seems to be a bit better too. One MAJOR COMPLAINT though: they start very, very poorly and hard.
When cold and pulling choked, one annoyance is that the cough you listen for when pulling, after which you off the choke and then expect it to start on the next 2 or 3 pulls, is barely audible, which caused many flooding situations until I got used to it.
But the MAJOR PROBLEM is that starting them when warm takes 4 to 7 pulls and that is ridiculous IMO. The brass tacks of it is that it caused nasty elbow tendonitis in me, and my 23 year old climber who is strong as an ox says it f's up his shoulder. And god forbid if a warm saw has been sitting awhile and youve got to decide whether to choke it or not based on how cold it may have gotten, well if you guess wrong youre looking at 10 to 15 pulls. It gets so you are hesitant to turn off the saw, and you send idling saws up to the climber so he wont have to start them aloft.
I start the saws whenever possible with them resting on the ground which is something Ive never done before and is a hassle and a time waster.

What say you, saw experts?? All input is thankfully appreciated.

I'm just taking a WAG here. But have you tried opening (richen)  the L side on the carb up some?

When it has been started do you put it in "throttle lock" position? Out AND in with choke before pull, it holds the trottle open about 10%.

Huge difference in the X-torq's than the old ones I bet.

I was at cut4fun's shop a couple weeks ago and the temperature was in the teens (F).

I had a 346XP and it was cold soaked. It started on the third pull with the choke full on which is very unusual. I shut the choke off and it continued to run but acted very lean. The saw had not been run since probably 70 F weather. The saw was still lean after warming up. I eventually had to open the needles some. When warmer weather comes I will have to lean it out some.

The Low jet is turned virtually as far ccw as it will go, just a tiny bit more ccw and the screw stops.

Trim the limiter tabs  (if plastic like on the old 372's)  off so you can get full adjustment.

What is used on the new 372 XT carb for stops? Never had one in here yet.

Found it on carb breakdown IPL. Not plastic tabs anymore.  Appears to be those metal stops like I seen on my newer 338.

I have one of these. You push the ring around the needle valve in with a scribe or point and turn the screw all you want.

You can take the screw out and the ring can be trimmed to remove the tab and everything replaced.

With a 19.05 mm venturi, that carb should be a very good option for many non-strato top ends, including the 372xp ones....

You have to use the 385 boot and flange as well as mounting screws and sleeves. The air filter elbow and blue choke rod parts have to come from the 372 XT to adapt this carb to a old style 372.

The problem is that the carb bolts are not straight across but one is high and the other low and they are longer

Two problems here, and two different solutions.  8)

Cold start: Do NOT use the deco. Not sure why, but I suspect this top mount deco drops the compression a little too much in addition to makeing that first "pop" harder to hear. Especially when the saw is new. People would come in with flooded saws that would really fog up the parking lot when we got them going. Part of the problem though was guys continuing to pull with the choke on waiting for that pop. One is a good friend of mine and fellow member on these sites. I watched him trying to start his 2172 and counted 20 pulls with the choke on before I yelled at him to stop. Every person that has had this issue has solved it simply by not using the deco.

Warm start: Carb is just not adjusted right, because this is not a problem I've seen with any of the saws we've sold. I suspect that it's a little too lean on the LO side. Every one of these things come out of the box too lean on both the Lo and HI. When setting up a saw I open them both at least 1/4 turn before even trying to start it, then adjust from there.
