Kevin,
I certainly would not start the engine
without a load on it. Things don’t always go as planned and more than one
person has scattered parts or burnt bearings by having the engine rev to
destruction without a prop (or some kind of load). Make sure you have oil to
the bearings. I would take off the oil line going back into the engine and
crank engine until I see oil coming out before I would even think of starting
it. Folks have reversed the Goes inna and Comes Outta connections on a remote
oil filter – and no oil flows.
With an idle setting of 1600 rpm – if I
take my prop off, the engine “idles” at 5000 + rpm. Crack the throttle plate
just a bit more and you easily may have 8000 rpm (or much more)
Just not worth it in my opinion.
Yes, if all goes as planned you may have
not problem – but, just bump the throttle cable or find the rev limiter not set
up properly and you could ruin your engine.
Good Luck
Ed

Subject: [FlyRotary] first start
check list
I am just about ready to try my first
attempt at starting my renesis. for my first phase, at least, I've chosen
to use a side draft Weber carb and DIS ignition system, which Lynn designed using an MSD ign box for the
primaries and 2 Chrysler elec ign's for the trailing plugs. I thought I'd
ask before introducing gasoline to my "creation" of any steps or
checks I need to do first. the engine and mount are bolted to a mockup
plywood firewall held up with steel legs. the psru is installed, as well
as the radiators [oil & water]. exhaust is just headers for now
[pointing down]. when I crank it over all the plugs are firing
[especially the MSD powered ones, which fire multiple times below
1000rpm]. the carb is brand new, with whatever jets they come with.
haven't designed a leaning capability yet.
1. I need to add a oil pressure gauge right
away. I'll need water temp after it gets running for any length of time.
put mineral oil in for initial break-in [turrentine engine, never run]
2. oh yeah, get it out of the
basement! guess airport best for making lots of noise
4. got the 6k rpm limiter plugged in to the
MSD
6. fabricate some remote throttle cable? or
do you just stand there and manipulate it by hand?
guess I fine tune timing after it is
running with a strobe light? I've marked the firing points on the
flexwheel. the pick-ups can be adjusted some if needed.
I assume I don't need a prop or club at
this point, right?
thought a small gravity fed fuel tank
would work at first.
should I buy new plugs? the used ones
that came with the engine seem to spark OK.
could I run this early on with the water
pump attached to say a 50 gallon tank of cold water rather than trying to get
it radiator cooled?
