It's getting a bit off topic but how does an 064 stihl stack up to a 288, comperable saws from same time period,(and i have an 064 but no 288).

Whats off topic? I thought the title of the thread was "talk to me about 288's"?
Did we stop talking about 288's?
Or have we just really confused you?
 
The 281 actually makes more compression stock than a 288 but suffers from less displacement. If you look at the 281 and 288 jugs side by side, the combustion chamber for the 281 is half again smaller.
If the 288 had come with quad transfers, it would be the best 80-90cc saw ever made.


Finger ports. :)
 
I don't know why anybody would want to buy a 20 year old 288 (whatever that is) when you could pick up a brand new 460 rancher for the same money

Surely you are joking Jon.

Is that where you grind out the transfer ports so big that you can stick your fingers in them?

Now Brad.....you know that would kill transfer velocity. :buttkick:

THe thread was talking about 288's. Talking 064's is straying a bit. Should I be afraid to post and be confused in your presence?
 
Wouldn't finger ports drop the velocity. Or is there a diff between one big transfer and two smaller ones

Yeah, a big difference. In a two port engine the transfer tunnels are big.....and sorta lazy. They even work better with different transfer heights than a tighter four port engine. When building a strong work saw, transfer height, crankcase compression, and transfer port velocity are the most important considerations. Say for instance you lower the intake, and raise the transfers......what happens to case compression????? And in turn, flow velocity thru the transfers?????

You've been here long enough to wade in any damn where you please Moe. :bowdown:

Relax buddy.......it was a joke. Go find Curly and Larry and give em a big hug!
No.....seriously Moe....was a joke. I'm cornfused all the time.
 
Lowering the intake is increasing the time fuel is flowing into the crankcase. In my mind that's increasing case pressure and faster flow through the transfers
 
Think of this though.....what about the other side of the stroke? When the intake closes, that is when case compression begins to build. If you lower the intake, you delay the point where case compression begins. Everything is a compromise, finding the best compromise is when an engine is not good, but great.
 
Just finished another one on Saturday. :)



Brad.....The whole "Lite" thing was an interesting marketing thing for Husky, but is super simple....It's a low top saw without the spring front mount. Nothing more, nothing less. The rumor that it has a lighter flywheel is complete nonsense. The 288's that came with the spring mount, have no rubber front mounts originally (Although some guys add them with the spring mount)......I love that family of saws right from the first 181se!! :rock:
 
The big spring and high top filter is the regular version. The lite doesn't have the spring and has the low top. Top ends are the same besides the early KS non decomp cylinders. They will make insane compression with machine work. The spring can be removed no problem.

Yep, Yep, and Yep. Brad you are in for a big surprise with a 288. Still my favorite in my bunch.
