ms290 fuel issues?

[a. palmer jr.]

On some 2 strokes putting the piston in backwards can cause an issue. This one just seems to have low compression though..

Sorry guys, I missed these last few replies completely. I have no idea about the history of the saw. These are just junked or scrapped saws that my friend picks up for his collection. Could be carb issues, could be piston skirt explosion. (See below)

Thanks for the troubleshooting help. It was definitely engine failure. Here's a photo of what I found tonite.



Ok. I guess I know how to identify "too much" blowback, lol! It makes perfect sense now that I think about it too. I should've checked it the multiple times I had the carb off. It is a learning experience.

Now to scout a jug and piston. These STIHL's seem a little more involved than the Husky jug/pistons I've replaced. It should be interesting.

Lol!!! Looks like a "modding" job by some of the guys here!!!

A little more work to change the P/C on a 290 compared to a Husqvarna pro saw but still not that bad if you have the time...

The 290 is back together. Since it was more or less a trade-out, I used a ms390 P/C from huztl to get it running.

A little more tuning, and she's out the door. A great learning experience overall. I definitely prefer the Husky P/C replacements.

Thanks again for all the help, guys.
