Ms 192 tc weird stalling after running

[BadgerClaw]

Got to check the basics and simple stuff first. No air in, no fuel out.

Thought I I did..
Anyways I took it off and blew it off with air didn't fix anything guess I got to order a new one.

Well I thought the issue was simple but just ran a compression test it held at 30.
Too low so I took the piston and cylinder out but no real visible scoring here are the pics. What else could cause low compression?

Using a compression tester that is not designed for small displacement engines!

OP now cross-check that gauge on a known good saw.

Lol this is why I ask you guys I'm just delving into small engine repair I've never had to go past the carb to fix anything.
Yep my ms250 that runs well is also 30..

I just don't know what to do at this point probably sell it, nothing I've tried has fixed it and I've spend 100 in parts. Now I am just getting angry with it.
Ignition coil, spark plugs, new carb , Fuel filter, gas, no scoring, gas cap off or on doesn't run so can't be the breather right?

OEM parts of China junk?

Well then the comp was good.

Possibly they are Amazon parts.
But begs the question now which ones.
Now I can barely get it to start for 5 secs before it dies then It will not start after that.
Should I suspect the ignition coil since I cleaned the og carb with with no success and tried 1 other

How crucial are the carb gaskets because I'm missing the intake side one

How crucial are the carb gaskets because I'm missing the intake side one

There is none:

Only a washer (14) that surrounds the sleeve (13) and the intake manifold lip (11,12). I think you need an IPL.

OP check the rubber boot for cracks 12 and make sure the ring 14 isn't missing. Are the carb and or coil china knock offs?

No cracks, ring is there. but yes the carb is China.

Well, you can not eliminate that as a cause of the problem now. Have you tried a tiny bit of gas into the intake and see if it fires momentarily?

I can what would that rule out?

What ,it will fire on a bit of gas?

Did it stay up when held by the starter handle? I rarely use a gauge for the reason stated about not being for a small engine.

 

[stihltech]

And chinese carb? Good luck. Took off a couple last week due to running issues.

Yea I am learning when I can and cannot cheap out I guess this is one of those
