Rap 24 hp semidiesel, first start attempt in 20 years.
This engine was built in 1930 or earlier. Have been stored outdoors for the last 20 years. After spending hours getting all parts movable this is the first start attempt. Seems to be low start pressure (6.5 bar) and low capacity in start air hose that is the biggest problem.
Rap 24 hp semidiesel, second start attempt.
This video illustrates what happends when these two stroke semidiesels run
out due to too much oil in the crankcase. With my left hand, I block the
injection pump, so from that time the engine run on lube oil only, no
diesel at all. I have heard lots of stories about this from decades ago but
this is the first time, to my knowledge, that it is captured on video.
Luckily we had blocked most of the air intake prior to starting and ended
at somewhat over 1000 rpm. Max operating rpm is 425-450. With full air
supply, I would guess this engine would reach thousands of rpm and I could
only guess what would have happened then...
The electric glowplug short circuited so we had to rely on the propane
burner which had slightly low temperature. In this startattempt, we used an
acetylene burner and got the glowplug bright red. The crankcase was,
unfortunately, filled with too much oil so the engine was running on its
lube oil from the crankcase instead of diesel. Still some trouble with the
fuel injection, doesn't feel right when injecting diesel manually.
Rap 24 hp semidiesel, third start attempt, the successful one.
More than two years since the last start attempt. Too many other projects
have had priority.
We used a couple of hours to get things running smoothly again and pumped
out more than 10 litres of rainwater from the crankcase but when we tried
to start, it went far better than expected :-)
The engine started running backwards and at time 3:00, I reduce the rpm and
give it a couple of manual fuel injections to change direction to forward.
MARS 5HP DIESEL ENGINE - 1st Start Up in 50 Years!
Watch as an early 1940's MARS Diesel engine is fired up after 50 years.
Originally acquired from a cane farmer in Nambour, Queensland, Australia in
the 1970's, this engine sat in careful custody with another three owners
before finally retiring with me.
MARS engines were made by the MARS Machine Tool Manufacturing Company in
Brisbane, Australia and were preceded by the horizontal and vertical Rapson
and Dutton engine, made by the same company under the Rapson and Dutton
MARS engines are not Lister clones. Mars engines are bigger, heavier and
more robust than Lister engines. When you listen to a Lister and then to a
MARS you will agree. This engine has a 3 " diameter crankshaft and not one
component is interchangeable with a Lister.
MARS engines were commonly used in industrial situations such as factories
to power line shafts which powered a number of machines, a task Lister
engines had some trouble with apparently with their crankshafts twisting
under the load on start up, and why this company made the Mars Diesel.
5 HP MARS engines were painted Maroon colour as standard from the factory
although there are variations of colour in existence. 8 HP engines were a
This engine has not run since the original owner sold it in the early
1970's. Apparently it had not run for some years before that. The second
owner sadly passed away before restoring it and it sat in a shed untouched
with the third owner.
Close friend and temporary fourth owner, Simon Devere, assisted actively in
the mechanical restoration when I purchased it and assisted in the first
start after its mechanical restoration. This man is a genius when it comes
to diesel engines and he has the nickname "The Lister Whisperer" for good
reason. Thanks "Slippery".
This engine appears to have not done much work judging by its internals.
Work to the engine includes new rings, liner/cylinder hone (the original
factory liner had indiscernible wear in it), new valve guides made to
original specs, new valves to original specs (original was bent and caused
damage to the guide) , new big end Babbit bearing, new conrod bush, very
light head machine to ensure true flatness, new internal oil pipes, new
head gasket, new oil gaskets, new high pressure line, new welch plugs in
the head and new oil pickup.
There are still remnants of the original factory maroon paint on it that
have survived the years of weathering out in the cane fields.
Cosmetic restoration is planned shortly to bring it back to its original
livery. It will be mated with a steel transporter to emphasise its
industrial heritage and will be rallied with pride.
Video of the finished engine on transporter will be posted when it is done.
Enjoy and please share if you like.
This is the only video of a Mars engine running to this date anywhere. Hope
to see more.
COX .020 Thimble Drome Pee Wee First Start in 20 Years

compression and with a .049 prop (5" 1/2) and first start in 20 years
pritty beat up but running strong.

1919 Buick First start since 1952
This is the first startup of this 1919 buick six roadster that had been
sitting in a barn in ohio since 1952. It was parked there with a bad
differential. My boss bought it on Ebay and i gently disassembled the
engine, cleaned out the 50+ year old oil, freed up the piston rings and put
it back together. I had to substitute a newer coil to get a strong spark
and had manually filled the float bowl of the carburetor. No fuel pump was
hooked up or water in the engine hence the short run time. This is a very
cool early overhead valve engine with an aluminum crankcase,cast iron
cylinder block, roller tappets, exposed valvetrain, zero gap piston rings,
and electric start. This car had about 14,000 miles on the odometer. Enjoy
