Hi all. This is my first posting to this group so please bear with me if I don't post things quite right. I recently started having problems with my MS191T saw. It would start up and run just fine. After cutting awhile and shutting it off, I could not restart it....seemed like it was flooding out (smelled gas). Tried starting it as warm or cold, it wouldn't matter. However hours later, or the next day, it would start fine, then cause the same restart problem. Suspected it was probably due for a carb rebuild, but I figured to take it to my local Stihl guy and let him check it out. He rebuilt the carb (I knew I should have just done that myself and saved $) and it ran beautiful again. Two tanks of gas later the connecting rod broke punching it through the wall of the upper crank case. I have since tore it appart myself, secured a used crank housing and nice used crack assembly on ebay. The piston and cylinder looked very good, so I just cleaned up the piston and put new rings & a new wrist pin on it. I'm getting ready to fire it back up but wanted to first see if anyone has any idea as the the root cause of the problem so it just does not repeat itself. I always used Stihl oil at the proper mix, and as far as I know, my carb settings were ok. The saw had about 9 years of moderate use trimming/limbing smaller stuff. Anyone have any thoughts?
