1940 Marna B 6HP start & idle

- Starting up my Marna marine gasoline engine. It was unusually easy to start this time around, last time before winter hibernation.
Before the restauration the engine had been sitting in a boathouse for the past 25 years or so. Lyckily the coolingwater jacket had been filled up with oil to prevent any corrotion for future repairs. It runs a little uneven due to a misadjusted carb.
wow! I guess these old brutts acted as a keel ballast at the same time.

Nice job there is nothing like the sound of an old low ram engine when it idles
Just showed up in my recommended videos.
I would love to have an old engine like that in a boat to cruise the rivers with.
Hi mate. This would be an excellent choice for that application. Nothing calms down the heartbeat like the sound of this at low RPM.
Cheers
Beautiful Engine
I must say I didn't realize that it was equipped with an impulse magneto (which also retards the timing for start). Nevertheless, one extra rotation before compression makes it quite a bit easier to start engines of this sort. It certainly helps old folk and people who lack arm strength. Clean air always helps, especially after a failed start attempt. Everyone has their own pet method, I suppose. Thanks for the video.
Very nice, lovely oiler, running good.
VERY nice!! Nice old tractor in the garage, by the way
fourforty RoadRunner Thank you, I'll make sure to relay your comment to my father. BTW, It's a Massey Fergusson 35, 1960-model.
Thanks for your comment. I should take some more video of it starting up.
I enjoyed watch you 'start up' procedure. Q. the little handle you wind- is that a fuel priming pump? I have never seen that before.
Cheers,

@Reece Gilbert The carb is indeed way more modern than the rest of the engine. I have obtained a more suitable carb that is under maintenance.
These engines are designed to just tick over the compression stroke in order to start. The ignition system is designed to make an impulse as the piston reaches TDC. This function is disengaged as the engine starts because of the centrifugal weights inside the magnet. Gaining speed on the flywheel in order to start is therefore obsolete. As far as I know cleansing the air inside the combustion chamber will in no way aid starting. Cheers anyway ;)
I'm sure my technique could be improved, because these engines should be easier to start than what is evident in this video. Unfortunatly, this old work horse is again hospitalized because of faulty carborator and the paintjob giving way to the relentless raw climate of the Norwegian west coast where I live. Anyway, glad you enjoyed the video.
Nice piece of engineering skill!
@TormodS76 Takk for kommentaren =).
Smøreapparatet på denne motoren er av type Bauer-Nilsen, produsert i Haugesund.
Alle andre 5-6HK marnaer jeg har sett på nett har hatt vekesmøring foran på sylinderen. I Bauerapparatet primer du systemet med å sveie rundt en rekke pumper til å smøre motoren. Disse roterer automatisk når motoren går. Jeg er svært usikkert på om 6-hesteren ble levert som enten vekesmøring eller Bauerapparat,
men på min motor ser dette ganske originalt ut.
@TormodS76 Jeg fikk ikke tak i ny toppakning og måtte lage "custom" pakning av noe armert pakningsmateriale jeg fant på jobben. 5-hk toppakning vil ikke passe ettersom sylinderboringa er: 5-Hk = 110mm, 6-HK= 120mm. Manifolden på denne motoren er uorginal, fra ein 5-Hk modell som jeg fikk av en lærer på videregående. Pusset den bare ned og hadde varmebestandig 600 grader C lakk fra biltema (ikke å anbefale egentlig). Bolten på manifolden kom heldigvis ut ganske lett.
Super cool engine. sounds great.
Try backing the engine up until compression is felt, that way you get a cleansing stroke and a chance to get more speed of rotation because of the extra turn you gain.
nice engine:)
Looking great mate run nice
+Cornish Engines Thanks bud :)
bonito motor, le queda bien el verde
To urządzenie potrzebuje ulepszeń :)
det vil nokk ha litt og si, både på lyd og gangen på motoren.
veldig fin motor foresten :) mer en ett par timer med messingpuss der ja hehe.
fint att dere tar vare på de gamle motorne :)
I have been offered to buy an old wooden boat from my neighbour. Perhaps if I have some extra money to spare I'll buy it and install this engine onboard. Only downside is the monumental gasoline consuption this engine has, 4l/h at idle speed.
@KapteinOpel Kan godt hende du har en 5-hester, type H. Dersom pluggen sitter i en forskruning som på denne, er det en 6-hester. Dersom den har fordypning, er det mest sannsynlig 5-hester. Type H har også mindre svinghjul.
They built them solid back then.
With proper care, it'll last several lifetimes :)
Jeg har en som ligner veldig, men uten slik smøreapparat. Tror den er litt nyere. Den har også sveivstart, sveiva sitter på et "tårn" som er montert der det fremste firkanta lokket på giret er på denne.
@gengnepal 4 stroke, the valvelifters are visible at 3:31
runs nice
Excellent!
My favourite colour!
Utrulig fint restaurert.Dette var tider der norge enda hadde industrie ;-)
@animatedsteel This engine is equiped with the "Bauer-Nilsen" lubricator. It was a stadard for virtually all norwegian engines in the past century. Before start-up I wind the handle to activate the internal pumps and prime the engine with oil in three specific areas. When running, these pumps are driven by the motion of the water pump-eccentric.
Thx for your comment. CHEERS! :)
looks like you making coffee in the beginning
@lovund86 Motoren var bare en stor rustklump når jeg fikk tak i den, kjøpte forgasser og magnet brukt for 2500 Kr.
4 stroke or 2 stroke?
@37Flat Thank you :D
@lovund86 Skal se om jeg ikke finner en annen type eksos.
Najpierw trzeba zmielić troche pieprzu, potem dolać keczupu, potem zakręcic wielkim kołem a na końcu powinna wyskoczyć kanapka... coś tu nie działa :(
Gracias ;)
Hæærli :D fantastisk vakker lyd :D
Thanks :D
6 hp. / 600 lbs. The way things should be.
Little need for extra ballast with this baby on board :) Thanks for watching. Someday I'll be posting a new video where I've installed the original carburettor on the engine.
Hell yeah :D
Nice...
Ja bym na początek spróbował zmielony pieprz i odrobinę majeranku zmieszał z keczupem i musztardą a potem to wszystko wciepał do środka i zakręcił ;) Może coś lepiej ruszy ;)
I call it the "BB" Back Breaker xD
gi motoren mindre motrykk på ekson, alt for tynn slange til å få ut all eksosen.
swidish??....
lars gullqvist Nope, pure Norwegian :)
superiormusic ok Nice man i lov norweigan pepol. ..
Norge rocks.... xb
Hay
Flott klenodium :)
Alexander Kvale Mange takk. Jeg vurderer å male den opp igjen på en mer grundig måte en gang i fremtiden og sette tilbake den originale manifolden og forgasseren. Men nå for tiden er det andre prosjekter som tar opp tid.
fiffig!
vakkert
Is it just me, but i see a modern carb. on that. what a cheater xD
