Hey guy , I've seen a video of a guy filing his chain with the saw in a vise upside down. I tried it for a minute and watched a little fuel leak out. My question is, will this harm the saw in any way? Will it flood the cylinder, mess up the carberator in any way? Is there any downside to flipping your saw upside down with fuel in it, or do I need to drain the fuel first? Thanks guys
Well over the years I've tried many tricks including saw upside down with gas cap tight.
One think I do to get the slop out of the chain while I'm filing is to slightly over tighten ( not running saw like that) the chain. Loosen and adjust when I'm ready to began cutting.
However, SELDOM do I get serious about filing a chain in the field. Normally change one out and sharpen in the shop.
In fact I seldom file a chain on a saw.
I built a filing jig. I'm a lefty but file using both hands.
I made an angle guide and after years of practice prefere hand filing.
Ill try to attach a photo of my jig.
The chain is always put on the bar backwards and I file from the nose end. The chain is tight. There is a sprocket that changes to fit pitch. It's not complicated just takes Thought and practice.
