What's wrong with my 254XP?

[cliff-1972]

I got a 254XP that I just can't get right .I bought it used and fixed it back up.I installed a new ring,rebuilt carb and modded muffler.When I tore it down,the crank cavity had a mixture of water/oil in it .I guess it must have fell in a river.So,I cleaned up.Well when I got it back together and cranked it up.It turned some high rpms at idle.I adjusted it to about 3600 rpm,as low as I could get.I then set the high idle.This thing was turning 18K+ @ WOT.Is this right?I checked gaskets for vacuum leaks,but none there.I don't have a way to check the case.Do you think the modded muffler caused this?I didn't try running it before I modded the muffler.So,what do y'all think?

Sounds like you are running way to lean.

Could be I have tried turning the high mix out all the way no difference.

Hi Cliff,

When you said you checked gaskets did you mean that you checked your crank seals also?

Sounds like your saw is a good candidate for a pressure/vacuum check. I haven`t seen any muffler mod that would make a properly running saw unadjustable.

needs seals probably, maybe a walrus too.

check intake boot or pulser lines? does it have them? I know nothing about husky saws..

one things fer sure, it aint right

I have replaced the gaskets between the intake on head,spacer to carb.Is it possible for the case to leak?

 

[JohnL]

The case can leak at the seals where the crankshaft goes through the case.

Anyway to test them?

Close off all openings and see if it will hold pressure and vacuum in crankcase.

I use carb cleaner I'm not sure if it the rite thing to do .
but when you hit the leak you will know it.
