I'm currently working on a 372xp using a Tillotson HS-274. The Tilly carb has an external pulse (there is a barb coming out of the carb that is for the impulse)
I've been online easily for 8 hours as of right now trying to find information regarding the ideal location.
I've heard it doesn't take much to activate the diaphragm, but of course you want a strong pulse.
I read some drill into the intake adapter they're using as it provides a strong pulse, and the shorter the pulse line is the better.
Now when it comes to 4Ts, I was reading about NOT drilling it in certain sections to prevent fuel or oil from entering the impulse line. While I know nothing about 4-strokes, I'm wondering if something similar could happen if drilling the pulse fuel fitting in the transfers.
I appreciate any insight into this, thanks.
