Default OS GT33 33cc gasser

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

Nice, like the single prop shaft fastener. much more user friendly than having to drill 4 darn holes.
I'd buy it over the DLE 30 for that reason alone!

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.

LOL so true! And think about it this way! If you join the super saver club you can get 50 off the 419 price which puts it that much closer to the dle 30!! I love the OS reliability in their 4strokes! I have a dle 30 and love it, but a reasonable priced OS gasser in the same size! WOW!! So if OS can can translate the quality of there glow engines over I will be buying some of these little gems!! And if a 23cc comes out!! My wife is NOT going to be happy!

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...
