This kit will work on the
Jonsered 670,625,630
AS always I only sell what I would use in my saws which I use to cut wood to heat my house with.
If you encounter any problems along the way, I am here to help you through it.
This is a conversion kit includes 50 or 52mm cylinder kit, wrist pin bearing
,base gasket, carb gaskets, exhaust gasket and all other item in the picture that are in yellow . Not eon the 52 mm kits , I am now adding an exhaust shield. this will help
shield the cylinder from muffler heat.
I also include a work shop manual via email.
To avoid this happening again, use fresh premium gas which is less than 60 days old. Use an oil mix rated FD and a gas can
with a tight seal.
This will insure the least amount of water dissolved in the gas and the most lubrication possible.
I will also send this work shop manual so you can do this right.
