Thought i would give you all a day to tell me what you saw before i went and did the same.
First off....Yup, like has been said and implied all threw this thread, the Speed Demon 850 is JUST TO BIG!
And watching the booster trying to draw fuel and only being able to dribble is "dead truth!"
But this is what i notices beside from the bad Shake, dim lit video.
At the beginning of this thread when i keep throwing bigger squirted in it to fix the bog and every on said Put A 50cc pump in it. I never could decide if i should put it in the primary side or the secondary side.!? Well that video showed the primary side squirt er die out much sooner then the secondary.
NOTE: 50 cc on primary side.
I noticed that the left/drivers side Rear Venturi would dribble a little when i open up the secondary, manual.
In the slow mo video, even when the mains came on, they were more drippy then spraying.
Primary never did more then drip.
Why does it bog/act up, MORE when it warm then when i have run it for a while at eng temp??????
MY Answer: when the fuel come out of the mains in a dribble,(droplets) the bottom of the manifold is hot enough to put it into suspension...or more of the droplet into vapor.
My Cruise rpm is steady state around 12" of vac and 9 under slight acceleration.
My staging rpm is around 9" and i have a 6.5 PV in it right now.
Would replacing my 6.5 for 10.5 PV help????? Probably but not enough. The full throttle dribble would still be the same as we r at (0) vac at that point.
As far is the o2 meter. that is as much live data so far.
that was from about 20 mph in 3d gear 4000 stall up to 5000 rpm.
Ran out of road to go to 5800 rpm
Like the fact that it leaned down to around 12.6 then when back up to 13.5 and look like it was going to hold around there.
Note: only full throttle, is accurate numbers as the sensor is a foot from the exit of the exhaust
"Whats next?"
Well i want a ET slip with a good mph from this carburetor, then pull it off and start to figure out why the Proform don't pull as well on the top.............or that my butt odometer is incorrect and there is no different in the top rpm/ HP between carburetors.(same day same air)
Was going to have a T@T this week end but Mother Nature say NO!!!!
