When an accel pump works properly, it starts flow immediately at the squirters, and you can see the spring on the adjust slightly compress as you open the throttle. 015Ĥ - Return the spring to the proper position Then after that attack the bog if it exists stillġ - Reverse your throttle return spring to hold the throttle wide open (not running of course)Ģ - Use a tool to compress the accel pump arm all the way to bottomingģ - Measure between the accel pump arm and the accel pump adjuster, it should be. The bog is almost certainly a LEAN bog regardless of the smell and pipes, it would take a PILE of fuel to have a rich bog, rich conditions sort of soften acceleration, they dont bog if only slightly richĤ - Go back and readjust idle a/f screws to highest idle, doing each one is approx 1/8 turn steps and going to the next one to keep them all even

14 degrees initial timing can be smelly because of lower EGT leaving a little fuel in the pipes, plus that stink can stay for weeks if you dont run the car hard even if you do fix it Rich at idle can be tough, you cant go by smell. However, regardless of the PV, the ONLY time PV fuel can affect anything is when air is flowing past the boosters, meaning your foot is in it. The whole PV recommendation stinks of someone who doesnt understand the operation of Holley carbs Remember vacuum drops during acceleration. The guys are right, a 10.5 PV will open sooner, not later.
