stihl vs jonsered

[badcars2]

father and law and myself were cutting side by side today and i noticed his jon 2045 has alot more rpm than my 041. mine just seems to surge in the cut, seems to be a few hundred rpm fluctuation.
also when starting cold, it has a terrible flat spot when you throttle until it warms for a few minutes.
hate to fool with the carb but it seems the adjustments is where the problem is.
does the flat spot sound like to little or too much low speed fuel?
should i tighten the high speed in very small increments while working the saw to get more rpm. and how do i do this without crossing the line and burning my saw down.
by the way even with my lower rpm i can still outcut him easily, just sounds like my saw is kind of lazy, but has sounded like that the entire year i have had it.
thanks in advance............

Don't wan't to pee on your parade but the jons is a better saw. If you have a good stihl dealer local they should put your saw on a tach. and tune it to your alt. and temp. as a favor this should make it run almost as good as the jons saw . It sounds to me that your low is running a little lean.

I disagree as to whether the 2045 is a better saw...and I'm a Jonsered fan!

There isn't really a solid comparison between the two; two different eras, design philosophies and intended purposes. The 2045 is a "weekend warrior" saw, not made for day-in, day-out work, revs to around 13.5 but doesn't make enough power to pull a 20" bar with any comfort. It's at its best as a modest firewood saw, or around the hobby ranch to clean up storm debris, etc. within those limits it is a fine, modern tool.

The 041 is a workhorse of 20 years ago or so, heavier, louder, and won't rev so high, but it will work hard all day as a serious firewood producer. In my area, it was a solid harvest tool, for hardwoods to 24" (90% of our woods), and enjoyed a good reputation for dependability. In time, newer, lighter, higher-revving saws came into the pros hands, but for it's time, it was a great tool.

Take that 041 in for a carb kit, seal test, and have the dealer blow out the 20-year-old dust. It will still produce firewood for you for 20 more years.

Apples and oranges....

Sucks? I don't think so.

The 041 is 1/3 again the size engine of the 2045. In spite of it's older technology, and lower rpm, it will outcut the smaller engine in larger wood. In smaller wood...the higher rpm of the newer saw will win out. To maximize production, I would use the 041 on the butt sections and use the 2045 for limbing and upper sections (but not at the same time).

I second the opinion of having a shop do a tune-up.

Thats about what I meant to say also WRW, there is no reason to do a comparison between saws that different.....

ok let me regroup

one thing for sure, this saw will never out cut my 041. it is just a friendly thing me and my father in law have. and never tell me that this wal mart saw is more of a workhorse than mine, nuff said, ok!
now back to the real topic. if i fatten up the lo and lean out the high just slightly i think it will fix my little problem.
my sawgoes from 4 stroking to rev and back to 4 stroking, so it must be pretty close on the power side.
no i didnt mean to compare total different things, just the topic came to mind after a day of cutting watching an infereior product. who said that, i did, badcars. come get you some!!

OK, my sincere apologies to SawTroll. I thought Tennessee boys were smarter than that.

Again, I'll echo what eyolf said. Sounds like you may have an air leak and that could be the saws undoing.
