Dolmar PS-9000 Questions

[Woodplayer]

I've got a lead on a non working PS9000. Saw is complete but doesn't run, no other details on the problem, other than it isn't seized.
I realize this is a heavy saw for the power, but it would be a project saw and the price is right.
What are the known faults or weakness of this saw, are there any common failure problems?
What improvements were incorporated into the PS9010.
Are parts still available (P/C, coil etc.) Are there any after market parts available?
Has anyone ever done any porting or simple muffler modding and how did the saw take to the modding?

Sorry for all the questions but haven't found a lot of info on this saw.

I would think someone has some thing to add about this saw, or do no replies in three days mean don't touch it??

It means that the right people haven't seen your question yet - like Cuttinscott, 166, Spike60, maybe Ultra and more.....

Yes most of the parts are available! the 9010 coil and flywheel will be an upgrade!

It is a solid saw and if the price is right, I'd definitely go for it.

Dolmar 134

OK the Dolmar PS9000 was originally going to be named a 134 as introduced on the DEC 1990 front cover of "Chain Saw Age" a wee bit of trivia for ya.. When we first got the PS9000's they were a bit soggy in weight from what we were told they would be. That being said they ran OK but were governed through the coil at way to low of RPM. Then they came out with a unlimited coil for them and if everything was in tune they were better. But they ate quite a few coils and also I experienced quite a few seizures as well. The saw with the unlimited coil was a tad temper-mental everything had to be in tune for it to live and still today some still do.

Then Came the redesigned PS9010 and it had a different Flywheel, Coil, and a Tilloston carb instead of that damn Bing carb. Then the saw became reliable and it makes a great 28" - 48" saw if your only planning on a 20" or a 24" I would rather use the lighter PS7900. Both the PS7900 and the PS9010 turn 13,500 RPM but the hp and torque go up with the PS9010 from the extra displacement. The PS9000 can and should be upgraded to the PS9010 flywheel and coil as far as the carb change its not necessary but I prefer the Tilloston.

There has been many a rumor of a replacement for the PS9010 in the near future its been named the PS9900 I would love to see this but I'm not hearing anything good from the rumor mill as far as a ETA

As far as mods go this saw takes VERY WELL TO MUFFLER MODS. My next door neighbor has a PS9000 with the PS9010 ignition swap and muff modded and it is the only saw that gives my EHP7900 a run for the money.

I hope this helps

Great that you saw this thread, Scott......

 

[Woodplayer]

Thanks a lot Scott for your reply.......... As always you have all the history and details.

Just curious if you found that the seizures were caused by carb or ignition problems or was there another common fault that caused the seizures?

If you have a ball park cost on 9010 coil and flywheel could you PM me.

Thanks again!!!

So there was an unlimited coil available for these at some point? Reason I ask is I had a 9000 years ago and it would easily rev up to 14k...I slowed it down with more fuel to 12,500 and was comfortable with that. Everyone here told me I was F.O.S. and that the limited coil wouldn't go above 11,500.

 

[cuttinscott]

Its my belief that the Bing carb could not keep up with the extra RPM's of the unlimited coil.

I have had mine 25 years and until last week never failed me. a dirty carburettor and and now lack of spark, Yes it is heavy but cuts extremely well.
