First Start
Posted: Thu Jul 28, 2022 4:23 am
Exciting moment - I started my brand new Rotax 912 ULS for the first time yesterday.
Everything went very well:
Post engine inspection reveled a small fuel leak, from the connection to a fuel flow sensor - refitted with gas grade thread tape - fixed!
Will do a rough idle speed adjust down & check hydraulic lifters are all fully "primed" with appropriate clearance as per Rotax "purge" instructions.
Next start, will be with cowling fitted and once warmed, will fine tune the idle & do the pneumatic balance.
The excitement is almost too much to bear.
Everything went very well:
- Ambient 14C
Engine fired immediately & ran smoothly. Engine speed increased as it warmed up.
Idling too fast, 2300 rpm - easy fix.
EGT's almost equal - this should come good with pneumatic carburettor balance.
Good oil & fuel pressure
Took engine to oil temp 57C & coolant 60C
Charge 12.6V 2 amps
