Hi people so i have a china saw myself which has a 45 cc engine and wears an 18" bar but even though its a 45 cc engine is so hard on the rope..its quite hard to pull and i say this because a neighbor of mine let me run his ms 270 which is like 49 cc and it was way easier to pull the rope.. I noticed this is a common thing on china saws...the compression is just so high which may be good but i can start my 362 without the d.e.c.o easier than i can start the china saw which is ironic because the 362 is 59 cc and the china saw is 45 for god's sake. Just why do china saws have such impressive compression? Its just so hard to pull..And it turns out the wires from the switch on my grandpas saw are broken thats why the switch doesn't work no more.
