Making stromberg carbs and piston type carbs more efficient
 

Dear hypermilers
During my research into stromberg carbs found on v8s and the piston carb found on older toyotas I discovered that trying to adjust the needle setting or changing spring pressure or trying other conventional ways did not help really.
So what I did instead is I decided to leave the needle piston assembly intact and rather messed around with the fuel intake line at the bottom,I got this idea from motorbike carbs which are kind of like a stromberg carb but use a cable to pull piston and needle up for acceleration but the major difference is that motorbike carbs are very fuel efficient,the reason is that there is a very small opening for the fuel inlet to the needle whereas the car carbs have a huge f****** hole for fuel inlet,so what I did is fit a small blind rivet with the pin removed and a little glue. as a fuel controller and well the results have been impressive.

ps. if you are confused just look at a carb of preferrably single piston off road motorbike,especially the bottom where the fuel floater shut off valve is found you will find the intake line to the needle.
closing unneccary vacuum lines like the big ones from engine breather to carb will help if you go ahead with mod.
