Upgrade of Enjomor 36cc I4 DOHC Engine | Stirlingkit

Dear Stirlingkit customers.

Glad to tell you that the new D6 engines have been upgraded.

1. Some customers reported that the cable was too short. So we specially lengthened the ignition wire. And it's very easy to link. The distributor connector uses a compression method to make the connector stronger, and the line distribution has been neater. And this design makes the thread end not easy to break. (our team is planning to produce a new distributor)

2. In order to prevent or reduce oil leakage, the latest gasket is used at each joint part between the oil sump and the shell. Oil seals are added to the oil pump and water pump cover plates too. Before shipping, we have done performance tests, so when you open the lid, it's normal for you to see some oil there. pls check photos below.

3. The crankshaft support is replaced with a crankshaft bearing to make the crankshaft more lubricated when it rotates. Under normal circumstances, the color of the camshaft is brown. Please note that this is caused by welding, not rust. The valve nail is made of stainless steel to prevent rust. The rocker arm is galvanized to prevent rust.

4.The exhaust pipe is galvanized to reduce the welding marks and look cleaner and tidy.

4.The steel gear was replaced and quenched, which solved the problem of gear wear. A second gear was added in the middle to make the start smoother when the flywheel rotates at high speed. The diameter of the idle wheel has been increased to 5mm to make the operation smoother and more stable


5.The entire electric start kit has also been improved.The oil sight hole has been changed to the bottom of the exhaust pipe.(check the photo in the 4.) The air intake pipe is made of a boss, so that the screw will not pass through the air intake cover, and the sealing is better.

6.You will find that the oil pipe is not visible from the outside of the engine. We now install it directly inside the engine,making the oil pipeline more concise and better sealed, so that it is safer when starting, and the belt will not reach the oil pipe. What's more,we have increased the diameter of the pulley to make the contact surface larger, increase the friction, and better drive the operation of the water pump and the oil pump.

7.Several holes are made in the shell to make the bracket easier to install. the bottom is well sealed.The base brackets are all installed before shipment.

8. please note that we still use the three-ring Design.

9. Evey engine is well packed so that it can arrive to your home safely.

Later I will update more running videos. if you want to send it back to me to replace it, pls contact me. if you have any other problems, pls feel free to contact me. my email is service@stirlingkit.com.

Normally, the factory itself will diagnose the engine model depending on the professional experience and see if the engine needs to be dismantled for further check or not. They will directly upgrade the returned D6 engine if there are no big issues on the engine. The factory & Stirlingkit together will cover the cost of the upgraded parts, like the cable, gasket, crankshaft bearing, exhaust pipe, steel gear, electric start kit, and air intake pipe. If there are broken parts that are not included in the free upgradation after the technicain assessed the engine status, I am sorry that ENJOMOR needs to charge the fee for repair at cost price since  charged parts and the upgraded parts are not the same. Any repair costs caused by personal improper operation need to be borne by the individual.  Thank you so much for understanding. 

We will ask ENJOMOR to take a video after the upgradation is completed and make sure it runs well. We will send you the test video for you to check before we send engine model back to you. 

REMINDER: Please do not disassemble the engine model before returning the engine parcel.

    Somebody asked me to get this motor running for him because he couldn’t. I can’t either.
    WHAT is the firing order of this engine? I can’t find this info anywhere !

    I received my 36cc engine a few months ago. The packaging was good and the motor arrived undamaged. (It did take almost 2 months to arrive tho, just keep that in mind) I have been working on other RC projects in the meantime so I am just now getting around to firing it up. After priming the water pump and oil pump we were ready to go and It failed to start, so I looked a little closer and then realized some major problems. The wire from the (ignition box) was screwed into the wrong location, where the plug wires needed to be. Once I corrected that, it still wouldn’t start. When the motor was turning over I noticed the intake cam was sliding out of the front of the head. Then I pulled the distributer cap and realized the rotor was not tightened onto the cam either and was missing 1 of 2 of the Grubb screws, and the cam gear itself was not tightened on to the cam. The price point for this motor and craftsmanship is good, but the quality control is not. Honestly at this point I’m a bit nervous to fire up the engine for the first time wondering if anything else had been forgotten to be tightened. Also the instruction manual is not well written/translated. For those that are not familiar with how an engine runs I would think they would be lost.

    I have purchased my first engine (I’m sure I will buy more)
    I look forward to building it at the end of the month.
    It’s like a birthday present to myself. 😀

  • Simon: March 19, 2022

    I’ve managed to get it running now, great little engine.

  • Simon : March 18, 2022

    Mine has arrived but it won’t start, the oil pump had a really stiff point when you turn it over and there’s no compression on cylinder 1 so I’m not sure how it passed quality control. I hope they help me get it going soon.

  • Robert De Martini: March 14, 2022

    I just received a 36 cc Enjomor Eng and I’m having ignition/distributor issues

  • Christophe DEMOLLIENS: December 31, 2021

    J’ai reçu le mien ce matin . c’est un très jolie moteur ..
    Seulement je ne peux pas monté la pipe d’échappement , elle
    est vraiment tordue et cela endommagerait les vis de fixation sur la culasse ??
    Ma tête d’allumeur a la sortie câblage vers le bas , tous les ces moteurs que
    j’ai vue sont vers le haut . est ce normal ???

  • Bernard: October 08, 2021

    J’attends le mien avec impatience :)

  • Ben: October 05, 2021

    How do I get a black one?

  • Brandon : September 18, 2021

    I am so happy to see these improvements! Can’t wait to get mine! Great work!
