Lets say I have the chance to pick up a Jonsered 670 Champ- or rather what once was a 670 Champ and is now a lamb in wolves clothing?
Lets say the owner has removed and discarded the cylinder, piston and intake tract from the donor 670 and replaced it with the internals of a Husqvarna 61.
Somewhat of a step backwards.
Saw (as is) is complete and runs with no issues, 18" Oregon bar and chain- and the asking price has nearly halved to the point of becoming appealing.
No, I don't live in the States, Jonsereds are not that common here, finding the original parts to turn it back to a Champ, while not impossible- will take a long time and most likely be uneconomic.
So, it is wearing Husqvarna innards- what do I swap the 61 cylinder for?
I am thinking if I can find a good one- 268, but have 272 and 266 on hand if needed.
Remember this saw has been changed from external pulse to internal through the intake block pulse and if the top end and intake system were changed, my guess is it is also wearing the smaller 61 carb- that will also need changing to a larger venturi..... so maybe it might be easier to go back to an external pulse?
External pulse is not impossible to obtain in a 2## series Husqvarna cylinder.
So, what would you do?
Which cylinder might you lean towards to help get the saw back to somewhere near what it was when it left Sweden?
Would you leave it as is and be happy?
Would you walk away from the deal and leave the Frankenstein saw to someone else?
