Well up till last week my 170 cdi ran fine. Until i had to pull it out of the model and replace a lost needle valve detent. The detent came off due to vibration, sometime during a flight. <div>So, now with the engine in the model, it will not continue running. It sounds like its running out of prime. But the pump seems to be working fine. Can this be related to a bad ignition system? </div><div>It would start and splutter and back fire and be all over the place, before stopping. Fuel dripping out of carb. Needle valve open at my regular setting of 3/4 open. This is the setting that the engine has run on for all flights. </div><div>Prior to me pulling the engine out of the model, everything was fine, no issues. And now all this!!!</div><div>Lost for ideas.</div><div>
</div><div>Any help out there?</div>
