Title: Re: Repaired a Couple of Jin's Engines for His Customers
Post by: Raphael on April 22, 2024, 11:23:22 am
Bonjour,
I also contacted Jin for a problem with a faulty CDI module and he immediately offered to send me a new one.
I also had problems with my M91 but a friend helped me to repair it.
China is far from France, a very small market for them and I regret that there is no more in-depth quality control before sending to the whole world.
I also had the same kind of problem with my Enjomor MK3 purchased from Stirlingkit and again, we repaired the engine ourselves.

This might be considered warranty work. 

The customers mailed the engines to me. Both are new and had issues.

The M91 needed a new head and timing adjustments both for the ignition and the cam gear.

The H09 mini Hoglet single got a new cylinder and piston and needs a new connecting rod which I am not certain I want to tackle.
The original rod was bent and gouged part way through from scraping against the bottom of the bore on one side. I straightened the connecting rod with hand tools as well as I could without full disassembly. I did this just to get it running and tested with the new parts. It will still need a new rod as the one in this engine is considerably weakened. At the moment it runs.

I am glad Jin is standing by his products when needed.
