bangood Hit and Miss engine, flywheel grub screws?
« on: August 05, 2019, 12:37:27 pm »
Hello everybody,
I recently ordered a hit and miss engine from banggod and so I signed up here in the forum.
The first thing I found out is that the machine runs a lot better with "Alkylatebenzin Aspen 4" than with lighter fluid.
Next, I would like to build a nicer base under the engine and possibly paint it.
That leads to my question:
Has anyone managed to loosen the grub screws that hold the flywheels in position?
I have tried 2mm, 2.5mm and 3/32 Allen keys and no one seems to fit properly.

Best regards
Thomas

Welcome to the forum.

I just checked and a 2mm wrench fit the set screw on my engine.

Hello Gil,
thank you for the warm welcome and your answer.
I tried a 2mm allen key, but it slipped.
Maybe the screws have been over tightened.
I will give it a try again.

Best regards
Thomas

Sometimes the smaller Allen wrenches get stripped and have the corners of the hex rounded off. If it looks like that has happened, it can often be fixed by simply cutting or grinding a couple of millimeters off the end to get back to a fresh cross-section with sharp corner. Do be careful not to get it hot if grinding, as that will ruin the temper and make it strip again all the easier.

I've not had any problems with any of my screws backing out, so I suspect that they only need to be tightened to a good solid snug. If you need more than that, it may be time for a little dab (very little dab) of locktight.

Thanks Stoker,
I will try a new Allen key and if that does not work some locktight.
But that will have to wait some days, cause yesterday the new base for the engine arrived and there is some work to do on it

That's certainly a very nice looking base that seems designed specifically for the engine, and would likely go along ways towards taming the hop these engines typically exhibit.

Can you let us in on the source for that?

Hi,
I bought the base at a German company called "Bengs".
It's made for their engine "Karl".
Here ist the Link: https://www.bengs-modellbau.de/ersatzteile-karl/karl-fraesteile/karl-teil-1-maschinensockel-grauguss
The base is really heavy (about 2.2kg) and as far as I can tell of a very good quality.
I will post a picture, when the engine is mounted.

Kind regards
Thomas

Welcome aboard, Thomas...!!!!!


I am looking forward to seeing the Beng's base fitted to your M90 engine.

Thomas, the screws are not always easy to get the wrench inserted all the way. Sometimes it helps to put a little extra effort into holding the wrench straight and with a little pressure holding it all the way in. Some of the screws have something resembling loctite on them. Removing the lower piston ring also helps allow better and more complete lubrication. Mixing Coleman fuel or a pure fuel (with no ethanol and all the other poisons in automotive fuel) about 20 to 1 with Marvel Mystery Oil is a good idea.
Best of luck with it.

Hello everybody,
I have not made any further attempts with the screws so far.
But I filled the hole on top of the base with JB-Weld and epoxy filler and than filed and sanded the surface.
Here is a picture with the engine on top of it.

Next, the holes for fixing the engine have to be drilled.

That looks superb sitting atop that pedestal!

Maybe it's a little bit to large  ???
But there is enough space inside for the batteries and the ignition system.

Kind regards
