Re: Engine seems to start but rolls to a stop

Cool. Choose the height of the bracket wisely. Very important. Too high and the prop sucks air or comes clear out of the water when the boat pitches. Too low, and you risk pooping the outboard in a...

Re: Engine seems to start but rolls to a stop

Spray them hourly, lightly, with a good penetrating oil. Then soak them down good before you leave the boat for the night. There was a thread recently, rating the various penetrating oil products...

Re: Engine seems to start but rolls to a stop

Let me try one more time, now that I have verified that the cylinders do indeed fire on ALTERNATE TDC positions, in turn.

When the pistons are both at TDC, and they will both be at TDC at the same...

Re: Engine seems to start but rolls to a stop

I suggest you stick with Deb's directions at this point. They are very clear and to the point, and will be easier for you to follow.

Re: Engine seems to start but rolls to a stop

Oh and the valve cover torque should have a specific torque listed, but it is not super critical. It is just to keep oil from slobbering out, mostly. Snug them down diametrically and just good and...

Re: Engine seems to start but rolls to a stop

I don't think you want to do both cylinders at the same time. Remember, in a cycle, there are TWO TDC points. I believe both pistons are at TDC at the same time, but one is at the end of the...

Re: Engine seems to start but rolls to a stop

What is your measured clearance? If it is within specifications then it is good. You measure clearance by seeing which feeler gauge slips through with resistance, but light resistance. Follow the...

Re: Engine seems to start but rolls to a stop

You are going to have to be a problem solver, and innovate. If you need a banjo fitting to connect to your injection pump, then get one or make one. If all of the points where a banjo is used are the...

Re: Engine seems to start but rolls to a stop

Ah my bad. I was reading and typing on my phone and I thought that was Justin saying he had tried gravity feed and it ran fine. Maybe I just had too many mojitos.

Re: Engine seems to start but rolls to a stop

I wouldn't be too sure about that. You just said that it runs great when you feed the injector pump directly by gravity. The problem seems to me to be located somewhere upstream from there. Try...

Oh I thought you only had hand start capability.

There are manuals, and there are manuals. The one I downloaded from I remember not where, is called

Re: Engine seems to start but rolls to a stop

Let me clarify. When the engine is running, all injectors are getting fuel. When the engine suddenly stops, and then you go for start again, THEN when you have the injector lines cracked open you...

Re: Engine seems to start but rolls to a stop

Looks like u getting very good advice in my absence. Absolutely, try gravity feed CLEAN fuel directly to injection pump, bypassing lift pump and engine mounted filter. Yes the peripherals are...

Re: Engine seems to start but rolls to a stop

See attached pic. This is from DV-10 manual but same as DV-20 except while one of your TWO pistons is on the compression stroke, the other is on the exhaust stroke. At least that is my understanding....

Re: Engine seems to start but rolls to a stop

Youtube is your friend. Watch as many vids as you can stand. Also remember that even though both pistons on your engine are at TDC at the same time, (I believe, not a lot of hands-on with Bukh 2...

Re: Engine seems to start but rolls to a stop

Great! You should be go for a start, in a matter of hours. I will check in on you when I can but I will have limited communications for the next 5 days or so. Good luck!

Justin, do you have some Marvel Mystery Oil? It is a much loved product for unstucking stuff and getting it going smooth and slick again. A teaspoon down the hole should slick everything up nicely....

Re: Engine seems to start but rolls to a stop

Can you tap it down? It must not be riding in the tappet on the cam. It should slide easily up and down, and as the cam lobe rotates upward is when it should be pushing the rod up. As it rotates back...

Re: Engine seems to start but rolls to a stop

If you have a valve that is not opening when it should, resistance to cranking would be expected. And just to be very clear on this, you have a valve that remains closed, and is not opening, due to a...

Re: Engine seems to start but rolls to a stop

The nozzle, is that just a flared out end, like a rocket engine? Looks like the pics in the following link? https://www.1tomplumber.com/what-is-a-flare-fitting/

Re: Engine seems to start but rolls to a stop

The nut looks like an ordinary compression nut or maybe a flare nut. I believe you can repair the pipe yourself. The end of the pipe up inside the nut... is it flared, or is there a beveled...
