Thats a good one, might try it one day.

Regarding all the other 'suggestions'; been there - done that - timing, porting, induction, tuned pipe, compression - all. There are two things I havent done yet - build a small gas turbine and supercharge an engine. I am getting exceeding lazier later in life, dont see myself machining an impeller - thence the cox shortcut.
Seems like the little cox is not really the ticket afterall - Ok, lets see, I have a turkey to devour, and I could mull over the idea of what to do with all those little engines later.

In the meanwhile, it is forecast to be a dull, rainy and snowless xmas.

Merry Christmas to you and yours

Merry Christmas to you too, man. Good luck with the search for more power.

Don't give up on your ideas. Try it on a smaller motor if you want. Failure is only another lesson learned, and more experience gained. Heck, I'd be behind you if you tried to supercharge something with a balloon! And Merry Christmas to you too.

Sid,, what weedeater motor is this any way ??, I have a (new, never used) modified Homelite 30cc cylinder for sale,, with a piston change it will fit the Homelite 24cc..

give the supercharger a go -
the mechanical losses on positive displacement types are pretty high and the turbo or centrifugal types are really of limited performance in very small sizes-
A piston setup is likely the best - in that small size
The OS supercharger on th 1.2 fourcycle was the WORST supercharger setup I ever worked on.
They ended up putting highly restrictive devices and a small carb to try to limit the boost -all because as a glow plug setup it was destined to fail.
We made it work by seriously reducing compression thru grinding out the squish band in the head . Still the compression build up as the boost increased, tried to create pre ignition and detonation.
It did preignite like crazy in stock form
IF they had opted for a spark ignition (and there were no good ones at that time ) it could have worked very well.

Nope....He asked to name one that "works"...and thats all im saying on this

Boosted Weedwacker

I think supercharging a two stroke is a great idea in fact i'm building my own supercharger but the problem is finding the perfect carb I would say I'm 25% done. I'm supercharging a mac 1385L 32cc weed wacker engine I know the engine is crap but It's all I have anyways here's some pics of the engine and my project .

You got it Eddie.......The only substitute for cubic inches is, rectangular money.....

I have no idea id this would work...but here goes! Use a carburator with a float. Build a box just big enough to enclose the carb. The output from your blower will push air into the box via a connector. You may be able to "Test" this therory by using a high output electric blower (ac or dc powered) to simuate boost. A tube hooked to box would show the ammount of boost. The amount of boost woud have to be controlled by electric blower controls or a waste gate to relieve to much boost. May be kinda fun! Capt,n

I was just wondering, why don't you run a ducted fan engine with a brushless engine setup linked to the throttle channel and some kind of mixing to regulate it the same as the throttle or the amount you need....

With the latest technology in eletrics, that would be the way to go, all you would need is a lipo, a DF blowing into your intake or to manifold.... I like your perseverance, inspite of all saying there are better ways.... This is the way things get invented and go forward, because of crazy nuts like you :-).....

Could even use the aircompressor turned down a bit and mess around.
