Works great. Some mod ideas

The engine worked wonderfully right out of the box! A,few suggestions though. Make the cap that is removed the fill the pump larger. It is hard for aged fingers(75) to handle. Perhaps a t handle.
Also, make the gas control more sensitive. It seems like it is either on or off.
Again, a great little machine and would buy it again. Thank you.

V8 small block air filter

I bought the air filter the day it was released. It arrived with the wrong bolts in the kit but that’s not the worse thing!!
It will not fit the engine!! Hits the throttle lever,
Clearly not checked on an actual working engine.
I’ve spent a large chunk of money with this company and keep gettin let down by little things
Bolts missing, wrong bolts in kit, items not fitting as they should!

CISON 44cc V8

First, I really appreciate how much detail was built into this engine. I have only just begun to assemble it.
The fit and finish of this engine is incredible.
I have watched many YouTube videos of other people’s engines and was really impressed of how well they run.
When I received my engine, I opened the wooden box and inside was layer after layer of parts neatly positioned in soft foam.
The finish on my engine was anodized and it was flawless. So far I am very happy with my engine, and the folks at Enginediy.

PORTABLE HM-01 & ENJOMOR ENGINES MADE WITH A CUSTOM BASE

I purchased one of the Custom Base Fuel Tank Oil Pipe Sets for my RETROL HM-01 Hit and Miss Engine Model and it really made it stand out. But it was just missing something. I wanted a portable engine. I found a set of red wheels and made the front bolster and rear axle supports for it. It came out so nice I ordered an additional Custom Base for my ENJOMOR Making it a portable also.

Nice little engine

Nice little engine kit all the machine work was spot on went together well they have changed the crankshaft a little bit around the rod journal (for safety is my guess) after assembly and setting the ign point timing added Coleman fuel mixed 25-1 with 2-stroke oil and it started right up. I ran it about an hour and shut it down the next day it had lost enough compression so it wouldn’t start I also noticed that the spark was arcing from the point spring to the bottom of the engine base I added a little piece of shrink tube over the bent part of the contact and replaced the piston O-Ring with the extra one that was included and it cranks right up. I do wish it had a little more durable piston ring setup but overall a great little engine

CISON V8 cradle

I used the V8 engine cradle to build a “skid” for my engine using 1/2 inch aluminum channel. It incorporates the radiator with engine driven cooling fan, and an alternator driven ignition system. Using the engine driven cooling fan with the radiator necessitated a very compact structure. One consequence was that I had to make a water manifold to feed the twin water pump.
Notes:
The screws holding the fan shroud to the radiator needed to be longer. I found they are not metric screws, but ordinary #8 machine screws.
The oil feed fitting on the block to the oil pump is very close to the engine cradle so it is best to install the feed fitting after the cradle is in place.
The alternator bracket was not stable. To fix this I drilled and tapped a hole through the alternator bracket and the shaft supporting the oil pump/alternator bracket so I could lock the pieces together with a screw.

Beau moteur

Très belle mécanique,seul regret pour le prix, avoir supprimé la graisse de montage. Un peu léger.
Mais,je recommande pour les gens qui aime la mécanique

good quality and strong

the title is program .
it is good to handle , but the wall from the 8 mm socket may be to thick for the musa hm 01. it is usuable,but the wall from the socket needs more space till to the bottom from the sparkplug, means the wall from hex 8 mm have to be a little thinner for propper work especially at hm-01.

DC Generator and Accessories

Just go the DC Gen , This pieces is absolutely stunning ! The CNC Work is Gorgeous ! Get One ..... SeaYa .

CISON OHV V8 is fantastic

I have built several model engines and they all were difficult to get running involving many hours of experimentation and occasionally replacing a burned out starter motor. The CISON V8 fired up on my first attempt! I even used only a 7.4 volt battery to reduce the strain on the starter motor and this was perfectly adequate. I built the (surprise) circuit board into the alternator and it works perfectly. I have yet to install the cooling system but the double gear pump and large radiator should actually work, in contrast to other engines where the water starts to boil after a few minutes unless a large external water reservoir and an auxiliary water pump are added. Finally, after adding the ignition wires, the oversize distributor is no longer so obvious and it is the best looking engine ever. I only wish it would come in Ford blue since it looks much closer to a Ford V8 than a Chevrolet V8.

My first 3d puzzle!

I enjoyed myself. This puzzle was perfect for a beginner. Shipping was fast, price was reasonable and its missing no parts. The instructions are easy to follow. My only issue is in the beginning it doesn't specify to use the little baggie of nuts for the A1 and there were no provided mounting screws for the maintenance platform, but I was able to use 2 different screws and nuts from the spare parts. I will be trying others soon.

Manta Ray Kit

I have been building models and kits for my entire life (I’m now 73)! I just completed building the Manta Ray Kit I purchased from enginediy- it took me about 3-4 hours. It is one of the best engineered kits that I have ever put together- everything worked as it should upon completion and it by far is one of the best looking! When turned on the movement conveys a great simulation of the movement of the Manta. I recommend this kit to anyone that likes a nice build

It’s not the attention to detail like the jet engine

Just received this engine, on first glance, parts look amazing but instruction manual for assembly leaves a lot to be desired. No parts labeled and a lot left for interpretation, along with the fact that you will need a magnifying glass and careful and precise interpretation of the instructions. The parts are of high quality but assembly instructions leave a lot to be desired compared to the jet engine that was assembled prior too

very good

Wirklich gut gearbeiteter Motor, lief auf Anhieb an. Der Hit and miss Zyklus war schon perfekt eingestellt, der Motor hat schön lange Aussetzzeiten. Gut Ölen ist wichtig.
Sehr empfehlenswerter Motor, läuft ca. 20Min mit einer Tankfüllung. Als Kraftstoff habe ich Feuerzeugbenzin mit 5% Zweitaktöl verwendet.

tiny but strong

this tiny sparkplug makes a good "fire" within to the minimum from the CDI.
the title of this review is program

Superb little steam engine

This is an amazing little steam engine. It builds perfectly and runs with no effort at all. Quite quiet too. I used about 10ml of ethanol as fuel and it ran for about 5 mins, with 50ml of water in the boiler. Not difficult to build so suited to a beginner too.

Fantastic model kit

I've reviewed this kit for Model Ship World, here: https://modelshipworld.com/topic/36587-5-cylinder-radial-engine-teching-enginediy/

Absolutely fantastic, fits perfectly and is a VERY high quality model kit. Far better than I thought it would be.

12V DC Generator and HM-01 engine.

I bought this mini generator to run with my HM-01 hit and miss engine. It arrived boxed and well packed and is absolutely beautiful. It is really well made and finished. I’m in the process of making a slide to mount it on as I think the belt tension may be critical to smooth running. I recommend this product and will update this review with new pictures when I have finished the slide.

Nice engine

the engine was well packaged.
no damage was seen at the cardboard box .
she runs out of the box.
filled with 6cc of alcohol(ethanol),
all movable parts are gently oiled
without the piston and the flat brass sheet in front of the cylinder.
the base of the tank is very nice made
and looks very fine as a part of this engine. i'm glad to have this .

runs very vell

the engine runs very well, interessting piece of technik. I use lighter fluid with 5% two-stroke oil. Shipping to Germany took 2 weeks.
I have fitted an 3d-printed exhaust that has reduced the nois by half.
All in all, a highly recommended, reasonably priced motor.

Amazing kit with reworkable assembly instructions

I think the model is fantastic, it works perfectly, the size is just right, the material is high quality. My only concern is the assembly instructions, a model kit of this calibre would come with a similar calibre of instructions. It is only for this reason that I have given it 4 stars, with a heavy heart, because otherwise it would be worth 5.

Very cool see thru engine

Runs very well, had to change the spark plug cap because it kept falling off... but runs well I'm still breaking the engine in with a rich mixture and very happy with my purchase.
