saw troll ahs brought this up

[J.W Younger]

many times. The 346 has better throttle response than the dolmar. I don't doubt this is true, my 5100 is not real snappy on the throttle but is a good power to weight saw. Just wondering if anyone had any ideas why 2 similar bore and stroke saws would be so different in that respect.

port timing?

So mod the muffler,,port the exhaust,,take the carb limiters off and adjust the carb as it should be.
then let Dolly have orange - juice for lunch..
need more info ?? ask C-town ,,the dolmar Daddy

port timing?

Carburetion
Ignition timing
Flywheel mass
Weight and balance of reciprocating components
?????

Anyone ever weigh the flywheel and clutch assemblies on those two saws? I'm betting the Dolmar is heavier on both sides. That may explain why stock out the box the 5100 will give the 346 a good whipping in the block but not up in the limbs where snappy throttle responce is nice.

I blame it on magic or gremlins.

that makes sense Tom, so does port timing but the mass thing seems more likely.Overall weight is close tho so...I donknow...

I'm sure there are alot of factors, weights just being one. Tolerances in the cylinder and bearings could be factors too. I was watching a show on TV one nite. They were showing a Nascar V8 enigine. It had a wheel bolted onto the front of the crank. With all 8 pistons installed the man could spin that engine like it was nothing. He said fricton must be removed to get every ounce of power out of the engine. Sad part is the motor is good for 500 miles like that..

Sorta a 500 mile fuse.....Top Fuelers have a 1000ft fuse.

Hey Tom can you tell me which clutch is which?

 

[volks-man]

if mr. hall can't tell that just by the markings he needs new glasses.

Dayummmmmmmmmmmm that top clutch is tiny, let me guess, 346?

Even the 260 clutch looks heavier than the 346.

To be honest I didn't need to see those. I knew the 346 clutch is very small and lightweight, I have a 346. I also have a 5100. The clutches are nite and day on those saws,

I knew you could tell the 2 clutches apart in a split second.
I was joking about it being a hard question.

Now I admit I haven't peeked at the flywheels on them but I'm guessing the 5100 has alittle more meat on it as well?

Now your gonna have to pull the flywheel of both saws and weigh them.
