dolmar 5105
DIR By: brokenbudget

---------------------------------------------------------
i've had this dolmar 5105 sitting on the shelf for a little
while, bought it new last summer.
once i have a couple more projects cleared up, i wouldn't mind
going into it.
so i've heard that there is another piston that can be used,
with wider skirts. what piston and what am i looking at to get
it to fit properly? not looking to go extremely wide on the
ports, but i do want a little more meat on the skirt. for the
first go 'round, i won't be doing any timing changes, just make
things flow better, unless somebody has some good numbers they
would share either here or in pm's. i'm not somebody that goes
around giving out info given in confidence ;). keep in mind this
saw will be used as a chainsaw.
any hints that pertain to the 5105?

They run pretty good the way they are. Mine is a early one. I
removed the 20" X regular 3/8" bar and put a 16" X regular 3/8"
bar on it. I also removed the catalytic muffler and replaced it
with a 5100 muffler. You might not notice it was changed unless
mighty familiar with 5105's.

:) already have the 5100 muffler on it. and that did make a
good difference. barely 3 tanks of fuel through it. and they do
run well stock. but i know there is more in there. :)

A Husky 45mm 51 piston works in 510-5100-5105. Husky 353 45mm
should work too. Iknow the 51 does. Haven't seen a 353. Cut
windows and trim skirts.

but no relief.

piston in the 5100/5's

I empathize on the toothache :'( . I'm pretty dang tough and
I've never had anything bust me like a toothache. Was in Fla
when it hit on a weekend too. Dang near OD'd on Ibufrofen
trying to get some relief. Wife said I was babbling
incoherently on the trip home.
Yes ED does post here.

:)lost a chunk from between 2 teeth a couple days ago while
flossing. felt something moving around in there the floss
couldn't get rid of so i broke out the water pik. blew a piece
out half the size of a 3 year olds finger nail. went in to the
emergency dentist (no pain at that time), she says it's infected
and i need to wait until that clears up with antibiotics. say
i'll need the hydromorphin when the tooth starts to dry out. boy
was she right. it's kicking in good now, i can still feel it,
but it's so far down there it feels like heaven right now.
i find it funny how a tooth ache needs to make my ass cheek feel
like it was ripped off ;D i swear, my whole left side hurts like
i have bad teeth all over.
thanks shep! i did see he was posting on here. just need all the
guidance on this one. if there is any benefit to it in a work
saw. :)
