Chainsaw Repair

Well depends on the saw model I suppose .The impulse operated  oil pumps on the 10 series and large reed valves were about the best ever built .The ones on the mini macs were about the worst .Then too compairing a mini Mac to an SP 125 would be like compairing a Yugo to a Cadillac .

I've never seen much less worked on a Titan 57 .I would have thought it was patterened after or like the Titan 70 but that evidently isn't the entire story . .Actually what I know about Italian made Macs is about thimble full if all knowledge of same would fill the Atlantic ocean ,I'm just dumb about them .
