Need help! Having a few issues!

[overtimegc]

I recently rebuilt a 372xp for my first time. It fires up and idles for a bit then dies. Restart is a bit difficult but I think it it’s running very lean. Part of the reason I believe this is because the cylinder is wet around the decompression valve and exhaust is wet around the exit hole. This is my first question. Is the decompression valve supposed to blow out like that?
Second, my clutch keeps kind of locking up. When the saw shuts down after revving up the clutch drum gets stuck in a raised position. It’s raised so high that when I tried to remove the circlip to inspect the clutch the washer put it into a bind and straightened the clip. The raised drum causes the chain to turn when I pull the starter cord. I can’t help but to think the oil pump drive wheel is not staying in the notches and causing this.
Any advice is greatly appreciated!!!

Sounds like your carb is flooding and the clutch isn't tightened back on correctly.

Can you take a few pics?

I believe the clutch is tightened correctly. Everything goes together fine.

What am I doing wrong with the carb flooding?

I’ll post pictures tomorrow.

Sounds like the carb is flooding, go through the carb.

Is this your setup?

Harley tries to help you and you say you believe he is wrong because everything goes together fine. I wouldn't help you if you paid me!

Rupedoggy please don’t stir things up and troll. I was merely stating that I had no problems installing the clutch, so I think. You may keep your opinions to yourself. In the future I’d recommend not reading attitudes in text form.

I know what it is, had the same exact problem on a 372 I built.

Do you mind sharing? Are you talking about the clutch issue or the carb flooding?

On the clutch Tim check the worm gear, I have had this happen on other saws.

Check the carb settings first.

Forget about Timmy. @cuinrearview He is a tiny little internet assassin. He likes to get in there with his advise that is about as useful as hammer is to tightening a screw. His main objective is to stir up trouble and try and bolster his self claim of being some sort of master technician.

I've read your description of the problem, and can't make enough sense of it to even form a helpful suggestion. It is certainly running rich, not lean. And I can make little sense of your clutch problem.

Makes no sense --> "clutch drum gets stuck in a raised position."

From your description is sounds like the clutch shoes are not retracting (weak springs), but that doesn't account for pushing the drum outward. Like Harley said maybe the clutch is not tighten down properly, but you would know more about that then any of us. And those things self tighten with use (i.e. reverse threads).

Thanks for the response Montana resident. This may be my first complete rebuild but I have had clutches apart before. I am human and make mistakes so by all means I’m not saying i know it’s perfect. Because obviously I’m stumped. After the saw is revved up the clutch drum ends in a raised position where the drum is trying to come off the crankshaft so the washer is pushing on the clip so hard I couldn’t remove the clip without it breaking. I could not push the drum down to relieve that pressure.

So I can now envision the problem, but I too am stumped as to what could be causing this.

I must be the outer edges of the clutch shoes that are pushing outward. And they would not do that on their own, so some part deeper in is the culprit. I can only suggest start by removing the clutch, and suspect anything that does not look or feel right. Pictures here and we can possibly help. Good Luck!
