finally dragged myself to the shop and did first test run.
idle: engine 1450 rpm, disk 898 rpm
full open: 3900 did not dare to run too long
ran at 3600 rpm, disk 2085 rpm
might want to limit the governor setting to do 3600 rpm till I'm comfortable
pretty scary to watch the new engine runs the chipper at that speed
Also, thrustle control is not linier at all. stay at idle speed till 2/3 pass FOT. Is it normal?
Yeah it jumps up on ya.
Just remember to let it warm up a good bit before bringing her up to speed.
The engine to disk is direct drive, no clutch.
You don't want the stress of the disk on a cold engine.
After I let it warm up a few minutes I super slowly bring up the speed to full throttle.
The governor will kick in at some point and startle you if your not used to it.
I do the opposite before shutdown.
Slowly bring it down to idle and let it run for a while for a cool down period before switching off the key.
If you just push the throttle to the low speed setting you have the disk spinning faster then the engine wants to run.
The disk will be forcing the engine to spin at the same speed as the disk.
Mine will pop through the exhaust if I turn it down too fast.
Don't be afraid of the higher rpms.
When your pushing wood through it you'll be glad to have them.
The engine rpms will drop when the chipper is stuffed or a larger chunk is thrown in.
The Autofeed will kick in some times and stop the feed wheel till the rpms pick up again.
I'd rather it not pause at a lower rpm, more rpms less pausing.
Just don't beat the thing till you have some break in time on that engine and change the oil after your first day of good use.
