Stihl 460 problems

[SilverKing]

Hi everybody.I recently bought a good running Stihl 460 at a flea market.Saw starts easy and cuts great,but im having trouble with it idling.It will sit flat on the ground and idle fine,but as soon as you pick it up,it starts to idle very fast.Then if laid over on its right side(bar side)it idles down very slow and will die.The high side limiter cap was gone when I bought the saw.Any help would be greatly appreciated,thanks in advance.

Sounds like a crank seal sucking air.

When you pick it up the intake boot is sucking air.

That could be too.

Likely lone wolf or redfin are correct (and ignore the other idiot), but I would also check the fuel line, and replace the filter & plug just cause U should.

If/when U check the boot, also check the impulse. line.

Good Luck, and let us know what it is.

He should start it and move top and rear handles back and forth to stretch the boot then it will be confirmed.

UR post was not appropriate or helpful, U don't do that to someone who is having a problem, it is like putting salt in a wound, just my opinion.

No problems Watson.I got to antsy and went ahead and tore it down tonight.Very noticable hole in the impulse line.The boot looks good,but I think I will replace it while its down this far.New fuel pickup line too .Piston and cylinder look great,at least no damage was done.Thanks again everybody

Great news, thought the impulse was a possibility! If U have not already done it, a HD-2 air filter and DP muff cover (and get rid of the muff baffle) really help those saws, just remove the carb limiters and richin it up a bit. And if U want to take it to the next level, porting really helps those saws, my 046 really woke up to the porting.

Glad U found the problem, glad it was minor, and enjoy the saw!
