Status: offline 		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?

No rail mount, rear carb, a prop stud like a G26..ETC.......

I'd buy it over the DLE 30 for that reason alone!

Status: offline 		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 issue is 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

Glenn Williams

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!

Status: offline 		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.

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

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...
