stihl 192t starts,runs for a bit ,then dies?

[skip sail]

Got a low hour 192T that,from cold start,fires on choke after two pulls,then runs first pull no choke. runs well for about 20/30 seconds then dies. Starts,then dies straightaway,then wont start.
any diagnosis welcomed!

Quick test. When it dies and won't start, open the fuel cap, put it back and see if it starts.
If not then you are probably looking at coil or kill wire shorting out.

check the muffler screen too. hell just take it out altogether....
also drop a few dribbles of fuel down the carby throat after it stalls to see if it will fire on a force feed....

Put me in the corner with a pile of Mini Macs I guess?

The pulse line on these saws has been known to come loose from the fitting behind the flywheel and also crack with age. NO dumpster, the 192T is a great little saw!

This would be my bet. You can prime it with the primer bulb, but it won't keep pumping fuel.

Carb kit, fuel filter and probably a new set of crank seals.

thanks for the advice fellas. decided to work through the options,starting with easiest first.
Removed the spark screen,a little dirty,but not too bad. still,gave it a clean,put it back in and the saw started 3rd pull and ran like a champ,no dying or bogging down,cut down a couple of smaller trees and limbed them,no problems.
How lucky was that? and how simple? Angelo,i reckon you saved me a lot of pull down time.
what surprises me is that there was very little carbon on the screen,but that must have been enough to throw things out of whack.
I had no idea such a simple thing could make such a difference.
Nice to get lucky now and again, the yard sale 192T that i bought for $25 because "it doesnt run" turns out to be a keeper

Angelo...

Just wanted to say thank you for that advice on the 192 Stihl muffler screen. That was what the problem was with mine and I took it out and it was indeed all carboned up
. Runs like a champ now. so thanks for your advice. I really like these forms. Saves time and money!

I wish fixing a saw was this easy for me. I am jealous.
