Vent Tube Question
Experts,
Have been doing a bunch of reading and noticed that Holley / Quickfuel, etc sell vent tube extensions and am curious if it would stop engine bogging when stopping. In particular, when I declerate on a downhill incline, the engine bogs and almost stalls. Same thing sometimes happens when I slow down though a turn. I am assuming it is a result of gas sloshing out of the vent and into the manifold causing a rich / flooding condition. Will taller vent tubes help? I have also heard of folks connecting the front/ rear vent tubes together with tubing an drilling vent holes in the top. |
Where do you have your float levels set?

First of all, I'm running a Quickfuel HR780. When the engine is running, fuel level is 1/2 way up the sight glasses. This is the way it was set up by my engine builder.

Try lowering the rear float level some . That should help on the bogging problem under hard braking . If that float level is too high , the fuel will spill out the vent tube directly into the secondary butterflies .
Had that problem at open track Friday at SAAC 36 and cured it by doing that . |
