Constant problems with 372

I bought a new 372 in February or so. Was having some neck issues at the time so didn't really use it much at that time. Last couple months I have used, at least tried, quite a few times. Runs for a bit and then smells like gas and won't start. I have taken it in 5 times now. Carb replaced, tank vent replaced and now the ignition. Anyone else having problems like this. Bought that model because I thought it had been built for a while and would have no bugs....If a problem again will insist on refund or replacement. Hesitant on the replacement as it would be the same parts and potentially same probelms!? Are they sourcing alot of parts from China? Maybe upgrade to the 576? Any suggestions welcome, thanks.
 
If it smells like gas, it might be some connection with the fuel line and the engine? I had the same thing with my first 540, turns out there was a brass fitting that wasnt pushed in far enough at the factory for that batch of saws i guess. with use the fitting works its way out, leaking fuel. took it to a dealer who was aware of the problem, he pressed in the fitting and put on some locking compound, and its run like a top since.

I got a brand new replacement saw yesterday, only the filter shroud and bar were from my old saw. Crane shows up, truck and trailer show up, saw won't start again. It never caught once. Took it back they forced some fuel out and eventually got it running....going back this morning to see if it will start. Maybe ask for 576 replacement....

Yes, initially was the fuel tank vent...seamed to be doing the same thing yesterday
 
So far so good. Had to take back to shop, take out spark plug and get flooded fuel out. Since then been starting and running ok. Seems to be a sensitive saw. Was told 10-15 tanks of fuel ran through to get it broke in and then should be better. We'll see. Thanks for the responses....chad
 
Guys on the new 365/372XT models donot use the decompressure when starting the saw , the hole is to large in the decompressure and lets to much of the cylinder pressure out for the saw to start proper , these new saws have a lot smaller intake port so draw a lot harder threw the carb so flood very fast . Just try starting without using it and you will find that the saw starts a lot better . Also if your gas has ethanol in it I find the 365/372 fuel line last no time and ends up getting a hole in it right where the fuel line comes out of the fuel tank , I have had some saws not last a month and get a hole in it
 
Yes on the choke and being a little sensitive to start it seems. Has been running much better lately. Seems after we got a few tanks of fuel through it much better. Yes, after it floods pain in the hiney. Take the plug out,dry and usually gets going. Little more temperamental than I was expecting.

I have to drive a little to get non ethanol fuel but try to do so as much as I can. Thanks.
 
my 365/372xt are the best starting saws I have owned , you just need to do things abit different also mine are ported and that helps starting as well . Guys if you find your saw is not idling like it should and seems to be running abit lean there is a good chance you got the hole in the fuel line, I just pull the fuel line off the carb and pull up easy , if the hole is to big the fuel line will break in half but if not the fuel line will pull up out of the tank, take a close look at the fuel line where it goes threw the fuel tank, you will see that spot pretty easy, look for a small hole . I only pull up enough fuel line that where I cut that bad spot out it fits back on my carb and that will still leave enough fuel line in the tank for the saw to run proper
 
Agree with ehp and ROYCE. No decompression, and it likes a little choke even when warmish, but really easy to miss the pop. My 372 had a really rough break in period - lots of flooding! Now it's one of my strongest running saws. So, be patient, there is light at the end of the tunnel.
