Crank Seals

[dono 57]

How big of a deal is it to replace crank seals on a Stihl 034.

Why do you want to?

I have a vacuum problem. It dont matter which way I screw my high and low needles it does the same thing. The intake boot ,crank vent are not leaking. I figure thats all there is left. Got a new carb , fuel hose and filters . Though it was the carb. I was wrong.

What are the symptoms?

A vacuum test will tell you for sure, low pressure air test will find it for you.

If your crank seal is leaking the saw will always be lean, even with the carb maxxed out
