Hello guys,
I have problem with mine freshly rebuild A12 engine in my B310.
Engine won´t start. Sparkle is there, but no fuel in cylinders - sparks are dry.
I have small fuel lake under carb, but no fuel is comming into cylinders.

Any idea, what can be wrong? Valves are adjusted, and timing looks good too.

Hi Winie, long time no see. Is it the same B310 120Y ex-Lybia?

To run the engine needs three things:
1. Spark
2. Fuel
3. Compression

Test the fuel. The carburetor has a glass sight. Is the fuel approximately 1/2 way up the glass? Or is it empty?










If the fuel is 1/2 full, next test that fuel is getting into the manifold:
1. Remove the air cleaner
2. open the choke (stick a screwdriver in to force it open)
3. rotate by the throttle by hand
Fuel should squirt out into the barrel of the carburetor. See Accelerator Pump Test
