Toyan went a did it!

For once I'd say Toyan actually made a proper engine. The fact that this flat 4 is nitro powered is smart. Nitro has plenty of oil in it. There are some minor quirks with this engine that need to be addressed.

1 the carburetor setup. It leaks to much air past and must be sealed tightly or you will run WAY to lean. Or not suck up enough fuel at all.

2. The exhaust valve on the left hand side. Mine and some others do not seal fully, causing hot gasses to escape and make the head run way to hot. You may need to adjust the timing by a tooth or two untill it's correct. Or take the valve out and lap it. This should be done at the factory.

Positives. The tensioner for the starter belt. Absolutely amazing and needed. It starts up with ease like it's nothing. No more tooth jumping.

Cooling fan, absolutely amazing and works as intended. though I'd make it out of metal as at high enough RPM and it will grenade apart.

Sounds amazing! This engine screams "I'm ready to perform" if you have been thinking on getting it I'd say go for it! You won't be disappointed! With this one! I've ran 5 tanks through my engine and she still runs like new.

It's a fun DIY kit for any mechanic you know. Or for someone who simply wants a desk toy to tinker on.

How Does Toyan Engine FS-B400 Works

How Does
It Works

The TOYAN FS-B400 engine works by drawing in an air-fuel mixture, compressing it in the cylinders, and igniting it with glow plugs. This explosion drives the pistons, generating power, while exhaust gases are expelled. A cooling fan and oil splash system keep the engine running smoothly, ensuring efficient and reliable performance.
