Hi all,
My MS 290 was running worse and worse, so I bought a replacement carb. Ran great for about 10-15 mins and now won't even start. I have spark and compression of about 135psi. I'm seeing 2 different carbs online and not sure which my saw takes:
HD-19B
Carb. HD-18B-HD-21B (only USA)
Is there a way to know which is the right one? I am in USA.
Thanks,
Jay
