valve cover pulse fitting place?

[johnf.357]

need to drill hole for the brass pulse nipple,on the 5 hole clone valve cover..

it looks like the best spot is right in the middle of the "o" in the lettering,(there is nothing behind that area to interfear...

anyone agree?disagree?

do it at the top facing straight up, less chance for as much oil, i solder the fittings into the valve covers. works great. Best place to pulse is off the intake so you dont get any oil at all......imo

someone correct me if i'm wrong, but don't you need to put the pulse fitting as close to the seal as you can? in other words, it needs to be in the blank space between the gasket and the reed valve, or whatever that's called. :shrug:

i don't want to sound like an idiot,(maybe to late) but what is the function of the pulse fiting and were do you connect the other end to? pics?

connects to a fuel pump that force feeds gas to your carb. the pulse of the engine pushes the fuel through the pump and into your carb. look at minidragbike photo album, you'll learn alot just browsing.
