On a stromberg 97, when the float level/gas level is set correctly, should gas be covering/going into the accelerator pump? When I turn on my electric pump/with regulator, gas goes over the accelerator pump. Thanks.
Here's the scoop on setting FUEL level as I posted it on here a while back. Note yo set FUEL level, not float level. Neither Ford nor Stromberg published float levels for this series of carbs because they do not react consistently to that setting--you set float so FUEL level is right. "The preliminary setting should be as stated, down around 1/4-5/16". Note the PRELIMINARY--Stromberg and the Ford rebuild info on this both call for setting by GAS level, not float level. Unlike the later carbs, the Stromberg's float valve setup was considered too weak and flaky to produce a consistent fuel level result from a particular float level. Ford set them after rebuild on a fixture under stock fuel pump pressure, which would be easy to do if you have electic pump. If you have good fire and health insurance, you could try the old timer's way of running the engine with tops off the carbs, or build a clear tubing device to screw into the lower jet port so you can read level in the tubing. This will read a bit high due to capillary action in the tube. The tubes sold for Model A Zenith fit those threads, or just drill and solder an extra plug for a tube nipple. You can also just measure after stopping engine, but who knows... Oh, yeah, numbers... FUEL level should be 15/32"-1/2" from edge of float bowl, measured away from the edge. Ford used a simple go-nogo gauge which you could easily make: One prong each for the two numbers, one should just touch fuel surface, other should be dry with the baseline of gauge bridging the bowl. Neither Stromberg nor Ford even gave a preliminary float setting--I guess they assumed normal stack up of dimensions with genuine parts would allow carb to function well enough to move on to fuel setting. The kits give a float setting because they have to give the poor customer something he can comprehend, I guess. Remember, the carb is now 65 years old and has been hammered on by generations of mechanics, hot rodders, and idiots, probably is made of mixed parts from several rebuildings, and likely has at least some damaged parts and some off spec repro parts. You may have to tinker the level a bit to make your particular carb happy. " Don't know why sentences are set like that...looks kinda like verse by Don Marquis or something...
Thanks for your help Bruce, but back to my original stupid question. Should gas sitting in the fuel bowl be over the accelerator pump. My carbs are running way rich. Both carbs have fuel level over accelerator pump with elect. pump on. should the fuel level be contained in the carb bowl below the accelerator pump? Yea, i'm stupid.
yes, fuel should be alowed to run over the slit running to your accelerator pumps. if it didn't you wouldn't pump any fuel
Stop looking at the damn pump and go get a ruler! The fuel level, measured slightly away from the wall, should be at about 15 or 16 /32" of an inch from the top edge of the bowl casting! I think that does put it over the pump, but measure it!
I ordered new floats, suposed to be here tomorrow, I will install them and carefully measure fuel level, thanks for the help, Dan
Another thought on the running rich: Try measuring the fuel level at the back of the bowl rather than front--I know there isn't much room in there to choose--because that's where its important in relationship to the discharge level. My thought is that this will account for any problem if carbs aren't leveled as original in your application. Once fuel level is established, you can try easing it down a tad if needed.
