New project off Craigslist this afternoon - Only $40 + $3 for a new starter rope - early-mid '80's McCulloch Pro Mac 610 w/16" bar,full chisel professional chain!!VERY CLEAN with little use. Guy wanted $70 which included another 50cc McCulloch late model saw in pieces but I politely explained the starter rope wasnt the right one & was too small.Plus he put STRAIGHT GAS in it last night (estate sale find he said) to see if it would run *GASP* So I asked him : "What's your bottom dollar on the 610,since it has the wrong rope & needs a few minutes work?" "I'll take $40 for it...." SOLD" 61cc powerhouse,will pull a 24" bar/chain with authority.I should know since I owned the same model saw for 19 yrs,used it heavily for 8 & sat under bench for the last 11 before selling it as a "parts saw" in March 2011. This new one wasnt beat to death like my old one,I had it running in barely 30 minutes.I'll keep it & use it as a backup trimming saw.That model was practically bulletproof,even though sometimes the carburetor could be finicky.I could tear it apart,sell the parts & easily double my money- but not gonna do that. From what I gathered - this couldnt have had more than 4-5 tanks of fuel in it,someone broke the original rope over 25 yrs ago then it was put away in dry storage.Fresh fuel mix in tank,shot of starting fluid,7-8 pulls & it was running great.1 pull after shutting off & it was going again.My old one didnt run this smoothly when it was new,was quite tempermental at times. Kinda missed the old beast so I watched & waited for a decent one at a good price. Much better shape than the old one with great compression & lots of power.
