Its just the nature of the beast...Most 400's have that noise.

Very normal, specially with the hotcam.

Mine was rather quiet, then I drowned it in a lake (dont ask!), now I had the topend apart and checked everything to be sure, put it back together and ticks louder.

Should be able too, might need to do 165-thats where I would start and go down from there.

Probably gonna have to screw the air/fuel screw in, the bigger pilots gonna richen it up for you now. Id skip the 40 and just do a 42.

Not likely. The valves on these engines tick, just the nature of thier design. Install a hotcam and the valves tick louder b/c of how much the cam lets them open/close and the duration.

Its nothing to worry about.
