    MS290 two stroking and losing gas

    I fired it back up and ran it for a few minutes. This time I could see gas vapor coming off the saw near the chain sprocket. Removed that cover and noted that all the sawdust underneath was soaked in fuel. Pulled the air cleaner and that compartment fuel soaked as well. Opened the tank and noted...

    MS290 two stroking and losing gas

    I just set out to get wood for the winter. MS 290 ran great one month ago. I filled both tanks and fired it up. In the time it took to cut one five inch branch, the saw started running rough. It sounded like it was two stroking like when at full throttle with no resistance, but it kept getting...

    Ongoing MS290 trouble

    You got me wondring about the impulse line. After letting the saw sit for a few hours, I chocked it and it fired up after a few pulls. I went to half choke and got nothing. I pulled the plug. It was dry. Turned the saw over and no gas ran out. I put the plug back in, went to full choke and...

    Ongoing MS290 trouble

    "I think you have your L screw too rich..at idle..go right until 'slowdown'..then left until 'S-D'..then set in the middle." What do you mean by S-D? Actually, I have put several carb kits in this carb. The reason I didn't this time is because the current carb kit has less than ten hours...

    Ongoing MS290 trouble

    My MS290 has given me trouble for several years. I am convienced that the trouble is carboration. I have to go through the carb once or twice a year just to keep it running. When it is running, I like the saw just fine. My brother has the same saw with easially twice the numer of hours on it and...

    Just terribly flooded. Got it dried out, tuned it, cut a bunch of wood. Everything is good again.

    Post muffler mod tuning

    I used a jumper cable, one end on the spark plug and the other to a piece of exposed metal. Spark plug is fine. The plug was wet so I think I am flooding the thing.

    Post muffler mod tuning

    Not yet. I wanted to but I can not find any metal portion of the saw that I can hold the plug against to see a spark. Instead, I dribbled a small amount of fuel into the cylander and turned it over. No life at all. So, at this point, it appears that there is no spark but I do not know that for...

    Post muffler mod tuning

    Saw got wet I forgot to mention. Last week, this saw was used to cut firewood for a camping trip. It was left on the wood pile over night and we had an unforcasted rain storm that was unreal. No one remembered to bring the saw in and it got a significant soaking. I have not tried to use the saw...

    Post muffler mod tuning

    Let as assume that a new saw is not in the budget. This saw is used for firewood and a little ranch work so having a bunch of saws just does not make good sence. Before the muffler mod, the saw was starting and running pretty good. I did the mod, cleaned the air filter and set H and L one turn...

    Post muffler mod tuning

    I have an MS290 that is now out of warrenty. It has been a good saw, but I have been frusterated with the lack of power when tackling big wood. Today I modded the muffler in hope of correcting some of this. I know that I need to retune the carb, but am not sure where to start because I assume...

    Everything I hate about my new MS290

    When I checked the air filter, it seemed to be coated with fine dust that was a little bit oily. I opened it up and found the inside was coated wet with fuel. I pulled the filter and started the saw. I am getting fuel mist from the carb during acceleration. I assume that this is not how it...

    Everything I hate about my new MS290

    I always use fresh gas from our local station, though I am not sure of the ethanol percentage. How much is too much? I am also unsure of how quickly they turn their gas over. I will check the vent, however, I did run a few tanks through before the saw got sick. It seems like a plugged vent...

    Everything I hate about my new MS290

    I appreciate this, truly I do. The reality, however is that we ranch in a remote location and we will work this problem out right here. Anyone who can help with this will be greatly appreciated.

    Everything I hate about my new MS290

    There is no sign of scratching on the piston or cylinder wall. I put carb cleaner through every orifice. Everything was visually clear. The fuel line is brand new, only a few hours on it. I just cleaned the air cleaner and may have found a hint. When I cracked it open, it was wet with...

    Everything I hate about my new MS290

    This may be a silly question, but here goes. When I put the carb kit in, I removed those silly limit caps and threw them away. I was surprised to see that the needle valves did not have springs on them. They are held in place with friction only. I wonder it the needles could be moving with...

    Everything I hate about my new MS290

    The filter is original equipment. I really miss the old style foam filters. They are so easy to clean in the woods. Is their a replacement "foam" filter for this saw?
