Husqvarna 394xp build

[Gord404]

Doing a build on a 394xp and thought since I have a near new crank from a Jonsered 2095 and are supposed to be the same I find when setting the squish the piston on a stock OEM cylinder seems to be about 25 thou to short in the stroke- don't mind shaving more off the bottom of the cylinder because I do have the setup to do it but was concerned if this would make any difference to how well she runs.

Are you saying the squish is .025, or is .025 more than the original crank? Squish clearance has a big impact on how a saw runs.

Well if you put a stock cylinder on there with no gasket the squish would be about 80 thou so I said screw it I will pop the cases and go with one of my 395 cranks and works out the way it should lesson learned, for an hour more work it is a sure thing and a lot less work in the long run- thank God for a crankcase splitter, sure cuts the time down. Done a lot of 394&5's so this seemed like the easiest way to solve the problem.
