Any one have photo's or any more information on the new 33cc gasser from OS. Tower's info is real sparse so far. Has it been posted anywhere else and I just missed it?

So all you conspiracy theorists, Which Chinese gasser did they copy ?? Or maybe a DA 50 ? After all, they LOOK like one...NO wait, the cylinder doesn't come off, just like a G38 or Q40/US 41...Side exhaust like most other gassers...
No rail mount, rear carb, a prop stud like a G26..ETC.......

Yep, two stroke engine designs are so unique they've been copied over and over for the past 50 years. It's all "new" every time a new engine is released.

Don't know what will be the price from others than Tower Monopolies but if they sell it under $400 the DLE 30 engine is in danger [img][/img]

I wonder if any of you have the GT55 version? Are they still having ignition issues or did that get resolved? If not I wonder if the issues will carry over to this engine? Don't mean to hijack your thread.
I really liked the GT-55 and it sounded great (kinda like a dragster) on a wrap around pipe. Anyway was just wondering if the ignition issueis fixed. I have been looking for some threads on that but other than youtube I have not been too succesful finding what if anything OS had done.
Thanks

I fixed mine by first running it on a DLE-30 ignition, then after Tower kept saying it was fine, I replaced it with a DA-60 that weighs less, runs perfectly and puts out stupid power.

Funny, Tower kept saying there was no problem with my OS ignition box! I wish someone besides Tower was the distributor for OS, because with Tower, you basically have no warranty.

yawn.... standoffs(should be beam -mount) rear carb (should be front) $419 (should be $319) the single-bolt prop hub is the only thing they got right. OS seems to be designing their engines in a bubble. I've heard-read that a 23cc is coming soon. maybe they'll get that one right.

O.S. designs engines for people that live in a bubble.

That is some twisted logic.
Your close and my close aren't close.
The $50.00 discount gets the OS 33 within $50.00 the retail price of the DLE30 yes but when you apply the same discount to the DLE 30 they aren't "close" anymore.
OS 33 $419.97 - $50.00 = $369.97
DLE30 $319.98 - $50.00 = $269.98
If the replacement parts for the 33 are priced anything like their 55 they will be astronomical.
You can tell your wife you saved $100.00.

OS 33
Price ""$419""
Prop ""20x8W 6,580 RPM""
-
now let's compare that to only 2 more cc, my MVVS 35 that I bought some 4 years ago,,
Price,, $30 more ($449) less muffler
Prop,, 3W 20x8 7370 peaked, Zinger 20x8 peaked over 7600
now the OS may be lighter and most likely is, but with those Prop numbers I don't think it will fly side by side the MVVS 35 or the Roto 35

Take a Look at the weight ,MVVS is very good engine but the weight difference is around 480 gram only on engine , also same weight difference with Roto.

HMMM, runs just like my MLD 35....
Or my OLD Bully 35, same cylinder as the old 3W 35...About 20 YEARS ago....Maybe I get a new Bowman ring for it and do a little comparing..The cylinder and piston came from a CHAINSAW....
Nothing much new under the sun..The Bully was about 20 YEARS ahead of its time..
How about the 3W 28, Pat ? You think your company will be using the NEW technology OS ??
Too funny...
