Compete with calm 180. Worked in the forest for 15 years, sawed calm-180. When starting the HUTER BS-45M on a cold press the primer several times (6-8) until the carburetor fills with gasoline, a characteristic sound is heard, then we pull out the air damper, start it, grab it and stall , press the gas handle and start it. I pulled it 5-7 times for the whole operation and started it. Or 10-20 seconds.
