Evolution engine dies when running full throttle
I have Evolution Trainer Power System .46 engine that dies when running at full throttle.
Well actually, my first problem is that most of time this engine starts in reverse. And my recent problem is that the engine die at full throttle.
After running engine for a few minutes, then advancing the throttle from idle to full throttle, the engine does not response quickly. Then it runs for a little while at full RPM's and then just dies... Matt's Reply: Using an electric starter?
Hello Hadi, It is common for an engine to start and run backwards. This happens more often when starting by hand or chicken stick. Are you using an electric starter? If not, I highly recommend purchasing one.
If this is happening even with an electric starter, it may be because the engine is flooded with fuel. In other words, it was primed too much.
If this is the case, just close the throttle or remove the fuel line and let the engine burn all the fuel out of the engine while running backwards, then try to start it again.
It sounds like your high end needle may be set too lean. Once you give it full throttle try the pinch test
. If the engine dies right away, it's too lean and you need to open the high speed a bit.
If the RPM's rise briefly before the engine quits, then it's too rich and you need to close the high speed need a bit.
Good luck, let us know how it turns out.
