It really likes it.Wow, should be enough carb lol
The carb would be a WJ, is that right?
If so, I looked at the metering on one of those once and there are three transition holes on the low speed circuit - so it should flow a lot more fuel down low (throttle response, torque). The actual size of the carb venturi wasn't that much bigger, but it did have a bigger section for the throttle butterfly. Did you have any issues blending the carb into the manifold, or did you just bolt it on?
Great mod.
@David Young How much?I just sold a very clean 390 on the bay. ]
The nylon mesh filter will flow more air, but a lot of the difference in this vid is due to the tuning difference. The saw is running much leaner with the nylon mesh. You would need to tune the saw with each filter for an accurate test.Air filter testing
