INTERNATIONAL LB COLD START THROTTLE GOVERNED ENGINE

This is DIRTBIKE5100 Trying to start his International Model LB engine with the help of his Father and Racer4560. It was difficult to start because the fuel line was loose and sucking air, preventing it from getting fuel suction. The temperature was over 100 degrees when they were trying to start the engine, I was glad I was handling the camera.

I just stumbled across this gem from years ago. Man Little Dirt Bike was young! I have two LBs running on propane. Great little engines.

last summer I restored a model LB 3-5 Hp that was gave to me from my uncle we ran it off a separate fuel tank for a bit to see if it ran but the threads into the mixing pot were all stripped out so the same thing happened but the gravity feed helped get it started all it needed was a fuel line new push rods and rocker arms and gaskets and my uncle said the oiler wasint working but after taking everything apart we found out the oiler only works after the engine is shut off it we are still confused about it now we were able to find parts easy in the usa the engine starts up in 2-3 spins now and now im fixing up a roller mill that came with it for a little fun at our local fair great vid love seeing old machines coming back to life

Man, that took some serious effort to get going. I sure was glad to see it finally fire up for ya. It ran real nice once they got it going.

Just goes to show sometimes something so simple can kick your butt.
Glad they got it going 👍

When it does go it's a very sweet runner!

One good trick for cold starting is to "lead the plug" electrode with a graphite pencil, usualy goes first time but you shouldn't need to do that.

I know it was a loose fuel line but hey, it works.

Edit my last comment. Did not realize you found a loose fuel line. But LB's a really easy to flood. Glad she runs. Mine is almost restored. I've had it for 35 years or so, since I was a kid, and just got it running again. Got any spare mag points? IHC mag.

yeah He learned a good lesson that day, make sure the fuel line is tight!! once he fixed that it started on first spin!!☺

[ROADKING]

They were used mostly by farmers who would hook them up to water pumps, compressors, cement mixers, saws and anything you could hook up to them with a belt!!☺

Makes you respect the classics, but appreciate the conveniences of the new engines.

@RamblinAround Between the 4 of us we should have figured out the problem immediately. I mentioned early in the vid that I didn't think it was getting fuel. We found out later when we where putting it away that the fuel line was loose. Little Dirtbikes Dad noticed it when he removed the gas cup.

I have a few of these MD engines in my collection. This is a good catch.

  BUT!! One should never leave the thumb wrapped around the crank handle when
starting.   If the engine should be improperly timed it can break the thumb off yer hand under reversing rotation on start.

I have a friend that has one, it starts right away. Fill it with warm water to pre-heat the cylinder (It helps) we run on gas until the water starts to steam then switch to kero. Fix what it wrong with and it will run well every time. Lost skin on my knuckle a few times starting it up...

Great little engine, just needs a little TLC and she'll be just fine . I got to say though my ears are still ringing from that starting handle snapping back on that flywheel 😆😅🤣👍👍🇺🇸

[gregoffenback]

Pouring gas through the exhaust valve is a new one to me. Not saying it is a bad idea, just never thought of that before.

[jhonnyhalls]

tive que assistir ate o final, pra saber se voces conseguiriam ligar o motor depois de tanto tentar, mas valew o esforço de voces.no meu pais e muito dificil conseguir um motor diesel desses, em seu pais parece ser mais facil. tambem gosto de fazer algumas gambiarras motorizadas, veja meus videos e da um joinha, valew abraço

[ROADKING]

@nave4pres2 Finally!! the fuel line was loose and was sucking air instead of fuel!! thanks for checkin' it out!!☺

[scdevon]

Remember when you were a kid and you always saw old timers with missing fingers and stuff?
LOL.

So You're lucky!
Here in central of europe, the situation is different... I was on search for an antique Deutz or Lister or Petter engine, but the search was hard and I only found restored (and extremely expensive) ones or totally scrap (and still expensive) even replacment parts are rare and expensive, so I choosed a chinese product - wich is not as well finished, but it runs well.

[sbartasek]

I don't think I could resist the temptation of using either a drill with a rubber tire mounted or a belt driven starter motor on that huge flywheel!

An LB with a good mag and a reliable fuel supply will start in 3 - 6 cranks after you get the hang of it. Fuel needle out 3/4 to one turn, choke valve pressed down and give it a good spin.
