Belt start?
On that old model 7,my uncle had,he rigged a belt,from the pulley of a John Deere B,to start the contrary saw.It worked,saved the arm .At 14 years of age,I could barely pull it over,and I never actualy knew the weight,but it was heavy.It did,however,have a chipper chain,that threw the biggest chips I have ever seen,because it was the biggest chain,I have ,to this day,ever seen.That saw was made when men were men .
I still laugh,when I think about the way the governer would "hunt",if the saw wasn't loaded,and him,yelling above the loud engine"lean on that handle boy,dang it".When my grandmother bought that McCulloch 250,I thought it was a gift from heaven .After that"little" saw,and a big old model 73 Mac,the old Mall went to the shed,never to run again .I sure wish I knew what ever happened to it,cause after over 40 years I'm over being mad at it
