Experimenting on a Saw...

[Stump Shot]

The carburetor would need to be mounted on the intake to the vacuum cleaner for the venturi effect to work. Might have a chance then, that is if the vacuum cleaner does not blow up. Lol

My next thoughts are to put a carburetor from a dirtbike on it and feed it from a elevated fuel tank.. i'll have hoses everywhere.

Could just be cause it's a Poulan.

The funny thing is when I start to put the pressure to it it doesn't sound like it goes lien it just falls on its face.

Placing positive pressure where negative pressure should be, would do just that.

I'm really hoping to see the video with a giant flame coming out of that saws exhaust in the future. Lol Keep at it!

Or some piston

Or some piston

Better yet!

Iam loving this and have you looked a centrifugal super charger were the carb is in a box on top of the intake

I think whats killing it is the pressure is making the fuel/air do 2 things. 1st...the "boost" is doing a u-turn in the crank case while the intake is open, it's the only place it can go. 2nd...if there is any trapped pressure once the intake closes, the rest of the fuel is being blown out the exhaust

Fill the shop vac with gas/fuel mix and add an agitator to atomize. Has to work.

 

[Dub11]

this is what iam talking about I think theres a reason the carbs in the box with this blow through set up

 

[TJ the Chainsaw Mechanic]

Might work on a 4 mix model as the valves would do the regulating instead of the piston. Some good points have been brought up to.

 

[XP_Slinger]

What about replacing the decompressor with a barb or something. Then you could use an air compressor to put the boost where it belongs...in the chamber. Would somehow have to time it to only boost once the exhaust is closed. Getting extra fuel would still be an issue. OR...Maybe a reed valve would let you pressurize the case?

 

[Dub11]

I was thinking that too on the decomp as a boost port. Now if only to get the timing down

 

[Simondo]

Exhaust gas driven charger becomes a reactive thing to engine rpm.. faster the engine ..faster the turbo... put fuel in that flow and "Bang"
I would have thought you need to go "Passive/reactive " on the air charge then you can burn more fuel.
I think

 

[spencerpaving]

In order to get the carb to work on a push through system the diaphragm has to see the same pressure as the intake.....on a float style carb you have to pressurize the float bowl otherwise fuel won't flow...pop off pressure would have to change too...

Just like an updraft on a tractor, I looked into a turbo and it just don't work

My brother talked with some folks at Garrett and they had no options for us. Stock carb is sufficient?

We wanted to put one on our Farmall Cub
