084 vs 088. Which is better?

[Brewz]

Great idea and reminder thanks [emoji1431] bought a p&c also [emoji1360]

You going to keep it stock Vince or do a bit of grinding on it?

I might go measure the timing on my 084 stock tonight

Put the timing wheel on the 084
97/120/68.

Has anyone ever put a timing wheel on the Cross performance top end?
@Mastermind ?

 

[Mastermind]

I did, but I don't recall.....let me see if I can find that thread.

96.5* exhaust.
might keep it as a spare and use the OEM jug.

What a letdown

 

[mdavlee]

96.5 isn't bad. 97 is stock oem. Still 120cc saw with plenty of torque.

 

[Brewz]

Yeah I guess.
Would have been happier if it was closer to 100*

Will see what its like when it shows up

 

[Mastermind]

When I port the 084 I do lower the exhaust. So I get what you are saying. The longer blowdown and extra intake should help though.

My 084 OEM P&C

It needs a birthday

The aux oiler cable is still good so I now need to work out how to get the tank handle off without breaking it.

Time to consult the ipl

I think I will start another thread on it's rebuild

 

[Brewz]

Dropped all the parts in the parts cleaner and they were boiling away after a couple minutes

Most likely keep it stock. It's just a just incase spare as I had to use my spare on the blown one I did. [emoji37]

Yeah for the price it makes a good spare hey!
I'm thinking I may juts keep mine in the box too and use the OEM top end.

flip the plunger for extra oiling ( next to the start stop lever) over. it pulls on a cable with a ball end. then its like any normal saw to separate.

That's pretty well the limiter on them. That's why they're such dogs now. A coil swap to a 441 or 361 coil if I remember right fixes that. They should be limited at 13k and you wouldn't need to mess with them. Same with the 9.6k limited 3120s. They cut at the limiter the whole time.

Ok.so this is how a 660 coil sits in there.

Turned these up at work.

Made a bridge out of some flat. And screwed it down.

Because the difference in the flywheel diameter, it needs to be tickled a tad on the ends. I just used a parallel burr.

nice work mate
I am going to run mine on Sunday with the 1308 coil but will be doing something similar to see how it runs.

Thanks Vince,

Wish I had taken photo's when I did it. Made a bracket like this myself.

I picked up a very low cost 084 today as a build project.
Its had a hard life, but I am not worried about looks on this one. I want to fix it up to be an ugly duckling milling saw.

I want to replace the clutch drum and oil pump worm gear with 088 units but have been told they wont fit properly?

Is this true or will they just bolt in?

Just want to find out before I spend the money

 

[Mastermind]

Are the part numbers the same?

 

[Brewz]

No mate they are very different parts.

The 088/880 has a system for the worm gear similar to whats used on 044/066
The older 084 has a different worm gear that requires a sprocket with 4 slots in it.
