Oxygen shots?

[creedman]

I have an idea that i was gonna try, using my gx200, a modified carb, and oxygen cylinders. I dont think the cylinders are pure oxygen, so it wouldn't be as dangerous, right? any thoughs are welcome.

Be like half a NOS shot, oxygen=dangerous

Good luck with that project. Why not be safe and just get those eBay nitrous kits?

 

[sayre315]

you probebly should use NOS because NOS kits have oxygen and nitrus the oxygen is for more fuel getting burnt and the nitrogen is to cool it down. if you use only oxygen it will over heat

Pure oxygen into the intake??!! YOUR ABSOULUTLY CRAZZY!!! That can make a HUGE intake back fire and litterly RIP your plastic intake and carb right off the block.

This guy knows what hes talking about.

haha thx, I have seen Nitrous back fires and there nasty!! espeiclly when using a big shot of wet nitrous system

This one time i was at the drag track and heard BOOM from the start line, from what I was told a defective NOS tank EXPLODED. Dangerous stuff.

Be more like 5x a NOS shot, nitrous is less than 20% oxygen.
The combustion would be so hot it'll burn right through the piston immediately.

thats giving me an idea.

i have a 3hp briggs w/ most likely a bad carb. and i also have access to an oxy acce torch setup. what about sending that mixture in through the carb as if it was converted to propane. or would that send me to the ER right away?

Only one way to find out, eh?

Just kiddin

 

[ed1380]

i just might. i got it started. works great for a 40+ year old motor. starts on the first pull and i didnt even adjust the carb

but i got to remove the dipper i made.

Briggs & Stratton engines last rediculously long times. I read a story in which a Briggs 2 horse was ran all its life (30-40 years) on WOT for whatever application. A few decades later, took off the head, 90% of the factory crosshatch marks were still there.

Odd, must have been some good cast iron.

 

[oscaryu1]

They were all aluminum blocks. 3.5HP's and up had I/C versions.

Heck, I have a 60's Briggs 2HP. More compression than any of my Briggs 3HP's with new rings, new head gasket, ect...

 

[ed1380]

I/C? internal combustion?

 

[oscaryu1]

Heh... Nice one <-

No, Industrial/Commercial. They feature cast iron sleeves. Heavier duty. Very common in the flathead kart industry. Unlike the Kool Bores.

Have you cranked them all backwards with a comp tester? The decompression system only works spinning the right way.

 

[oscaryu1]

Don't have a comp tester. You can just tell. I've had a few kids tell me the 2HP was harder to start. Accompanied by many flips because they didn't hold it down hard enough.

Could it be lacking a decomp system?
