I also am converting a asp 180 FS and plan to use a WT454 from a ryobi can the intake pulse be taken from the inlet manifold on the adapter plate and do away with the fuel lines?
Also the breather, could this run to the adapter plate also for the oil return.
Is the WT454 ready to use as is or does it need modifying for the intake pulse.
dogshome any further updates on your conversion, the video sounds great and idle is very smooth.
Could I suggest you use 5 cells on the ignition as I have found it gives higher rpm and reliable running.
Good luck on your conversion. My might consider starting a new thread for folks to follow your project.
The WT454 carb appears to need a positive AND negative pulse to operate. It's not set up to get it's "pulse" from the intake only. It could, perhaps, be modified to work like a WT-456-1 which IS set up to run from an intake-only pulse. See the instructions how this could be done yourself, assuming the pump cover and the carb body look like those in the picture.

If you use a carb that is set up to run on intake-only pulses, then you don't need to hook anything up to the breather(crankcase vent).
