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.
