powershot racing carb question

was just wondering if the powershot carb you sell gives a extra fuel shot when throttle is pinned fast like the big mx carbs?

while dealing with some jetting issues i noticed the 24 flatside carb may have a powershot sprayer (clear hose running to the top of carb opening)? if this is true, does anyone know how it works since there isnt a pump anywhere. i am familiar with the bigger bike pumpers. my wr250 sprayer had to be modded to work right.
also read some info on the 6 racing carb that g-force sells and they say it is a powershot carb. getteing that shot of fuel when throttle is cracked wide open sure helps the jetting problems for me.

115 main and 60 pilot seemed to have got rid ok the bog and top end is good for now. mixture screw seems to be comfortable at 1-1-1/2 out.

some pwk flatslide carbs are power jet and some are not.

Powerjet is for long wide open throttle runs and the vacum send fuel thru it to Richen the mixture so it doesnt lean out.

Very helpful in Drag racing and on scooters on the road.

Many debate wether it makes a difference in MX or not since there usually isnt long enough WOT runs

Stage 6 makes an awesome Quality Carb that is as good if not better then the Kehin - Stage 6(being from scooter origins) makes all of their flatslide with the powerjet.

Dana, I understood the powerjet to be: Once your at wide open throttle and you close it suddenly it supplies some fuel so that the engine is not running without fuel/lube while it idles down.
I run a 28 powerjet on my 70.
