Need help with MS362 issue...

[AKDoug]

I assume you've pulled out the exhaust screen Next thing. Have you pulled the cylinder and looked at the piston closely? I had a 362 come in the other day that had a chunk broke out of the piston directly in line with the intake port at the base of the piston. I pulled the exhaust and there was no scoring, pulled the intake and there it was. We could actually get the saw to run at times, then it would mysteriously die. All the pieces hammered one of the transfers and puked out the exhaust, so there wasn't anything rattling around. It honestly pounded or burned the pieces up small enough to go through the screen.

My next thing would be to find a carb system I could switch out and try.

Oh yeah, last thing. The ground wire routing is critical on this saw. If not snapped into the keepers it can rub on the bottom of the carb and created an intermittent short.

Maybe it just ran out of gas this time.

 

[young]

sell it as parts saw on ebay for big bucks.

That saw is "THE DEVIL"

Yep . . . just like the source!

Did you vac / pressure test the carb air boot or was that off for the test? If the boot ain't leaking I suspect the carb!

The exhaust screen is clean. The piston & cylinder are good - I had them off as part of this rebuild and they checked out just fine. I've had two other carbs on this saw and it behaved exactly the same way.

Ground wire is routed correctly and doesn't have any compromised insulation, and after it quits & doesn't want to restart I still have spark....

The press/vac test is done with the intake boot installed. My original assumption was the carb, but I cleaned & readjusted everything and when that didn't work I tried two other carbs with the same results....

So where are we at here now it just dont like to start or does it still act like the carb is bad? Where is the choke on that model in the filter?

See post #19 - I described exactly how it's behaving now.

Where is the choke on that model in the filter?

No, not in the filter. The MS362 is a strato saw, so the throttle & choke butterflies are stacked on the carb (choke on the bottom).

Leave that saw in the driveway and I will take care of it in the morning. LOL
How about I give you the 036 pro I have and you can start over?

I have two of the same saws at work. They take forever to warm up, and if you give them too much gas when they aren't warm yet, they die and are a pain to start, with or without the choke. If they run out of gas, forget about trying to start them right up after refueling. They need to set a little bit. They were pathetic when new from the dealer, but that mostly had to do with a really lean high side mixture (only 1/2 turn out). After removing the caps and richening up the high, they both run better but still have the starting issues. I am interested to hear what you come up with.

Good to know it will likely never perform 'normally'. As far as letting you know what I come up with . . . I hope to do that, but the sad truth is that I'm very near the point of jumping ship and setting this joker sale on the 'bay.......

I might sneak out there and set it behind the wheels of your truck before you leave . . . that way I'm done with it and I can blame you...

Have you pulled the muffler and looked at the piston ?

Try swapping the carb one more time I dont know what is left.

Yeah, I'd love to, but I don't have access to any more to try. I would love to know that's the problem so I could buy a new one and have this crap over with. At this point I really don't know what else to try...

WANT ME TO BRING A CARB OR 5?
