free non running ms 290

[ncsawguy]

Someone gave me a ms290. he told me that he had it looked at said cylinder was gone. but never took of muffler. but anyway it hold about 145lbs on the compression tester. it runs for a couple sec. I think the carb just need to be rebuilt or the boot needs to be replaced. might need an ipl any one have any suggestions. it was a pretty clean saw. thanks for your info.

Dude..friend..If someone gave you a saw..and said it had been 'looked at'... that should tell you it's a POS.

Why are you posting about it before YOU pull the muffler and look inside...then you'll know.

If cylinder and the piston looks good...yeah, maybe a carb re-build and boot replace...but I think you have bigger problems..??

145 lbs..( who did this test )..?? If it is that...then the cylinder should clean up if you are willing to do all the tear-down on a MS290.

I'll pass...as the saw is tooo heavy for it's power...not good resale value...and just a PITA to tear down - But good luck to you..!!

Well...you see that is the problem...that being the compression is just fine for say...a several year old saw.

That's why I asked who did the test..?? In other words...something(s) is just not adding up correctly here.

If we're talking about you helping a buddy out on a saw that you have no real interest in..."color me gone".

145-150 psi would be normal for an ms290.anything below 120 isnt good.100 usually wont start and run.

 

[jughead500]

Pull the muffler and see if there is any scoring.id say it just needs rings

 

[ncsawguy]

he was going to throw it away. I told him I will take it. the guy who looked at it told him the piston is scored and cost around 200 to fix. he never took off muffler and he was a dealer. so if I can fix it with minimal cost I will. twenty bucks is nothing for a friend who would drop what he is doing to come help you if you asked him too.

 

[ncsawguy]

thank you jughead. that's next. Im going to try carb kit next there was trash in carb. I asked my friend how could the guy tell if cylinder was scored or not if he didn't take off muffler.

 

[ncsawguy]

I don't think it even needs rings. I wasn't going to take it that far.

I've got an MS390 (same saw, just bigger cc) I got in a trade. Had to put another crankshaft, bearings, seals, rings into it. Did a muffler mod to it and it runs GREAT. About $50 in the whole saw. One of my favorite firewood cutters.

Through the spark plug hole..

Before I bought a carb kit, I would pull the muffler. It only takes 2 minutes and you may save yourself some money on a carb kit (and put it towards a long block 290 kit ).

Pull the spark plug, shine a good light in the hole and you will be able to see any scoring on the exhaust side. Scoring will look like discolored vertical streaking.

 

[ncsawguy]

thank you sir. the saw hadn't been abused. everything was pretty clean. carb kit first he said it sat awhile. less than 10 bucks

 

[ncsawguy]

i did shine light I didn't see anything wrong. nothing normal wear.

For real, take the muffler off for inspection. You want to do a muffler clean and mod anyway, right? Visual inspection with a good light will tell the tale.

 

[ncsawguy]

I will tomorrow.

X2.. Dont buy anything you don't need. It's a free saw. Keep it simple and cheap.

Your gonna take 20 minutes to clean and rebuild a carb that may not need it.

Take 2 minutes and remove the muffler.

 

[jughead500]

It will be a different saw with a simple muffler mod.check the spark screen to make sure its not plugged.

By the way OP, the resale value on the MS290 is very strong. It's a very popular saw. they cost $400+ new. I got $225 for the last two I sold and the next one I list will probably be for more. (looks matters).

I sold mine for $200 and it was well used.
