Chainsaw Repair

JMO and thoughts on this. The baileys univent xpw 75cc was done up to get around huskys new no online sales.

The univents that are sold by rescue saw company's and to fire depts are a totally different saws.  Here is a univent  by todays specs below. 

Mike I wonder with yours being 50mm bore if it has been replaced or maybe one that came in right after the 272 univents was phased out. All just a guessing game on my part.

The baileys 75cc I ran was no better  then a stock 372xp or xpw JMO.  Going by the univents sold by Unifire to FD's there seems to be some hop ups done

Powerhead Specifications:    Unifire specs NOT the ones that came from baileys.

    Saw power head must have 4.5 cubic inch (74 cc) displacement with a 2.05-inch (52 mm) molybdenum impregnated bore and 1.34 inch (34 mm) stroke.
    Power head must develop 6.5 horsepower at 8500 RPM
   

Well, the 75cc 372xpw has a 51.4mm bore, but Baileys stated 6.5 hp - I am no wiser.....
