Hi all!!


I'm coming here looking for help, and I'm pretty sure this is the right place. Some months ago my father bought a quad city challenger clipped wings with just 35 hours of flight in both engine and airframe. This sounds good, but the previous owner sold the plane for one reason: the engine became a headache Since the begining the things went wrong when one side of the ignition failed and he had to replace the armature plate.

At this point the engine ran well. Based on this event and on some histories on internet, he decided to get rid of the injection and replaced it with two bing 54, with the jetting according to the factory He sent the injection to the dealer and received the bings.

Once this done, the engine start to gave problems to accelerate. He worked on it for months and at the end he decided to sell the plane to us The problem is very weird: If you push the throttle slowly, the engine go up to RPM easily.

But if you push it in one shot from idle, it get stuck stumbling in RPM's, until you close slowly the throttle at certain point where it pick up again and you can open the throttle fast and it will go to again We have tried several things to fix this, for some months We have tested all the combinations of jetting that you can imagine, and all the positions of the jet needle, and adjusted the mixture all ways possible Recently, we started to suspect about the timing, so we checked the manual and found out that it can be adjusted, so we moved it in all the ways possible and the things went the same Now we have the suspect that maybe the E-Boxes, which are suposed to be programed, could have and advance timing map for and injected engine, and this don't mach with the carb behaviour.

All this being said, and sorry for made you read all this, we have no clue what to do next Any advice will be highly appreciated, greetings from Costa Rica, Esteve. The problem is that your are running lean in the mid range. When you open the throttle quickly the air responds more quickly than the fuel. Automobile engines solve this with the accelator pump which most aircraft do not have. There are several things you can do to minimize the problem but you may not solve it completely.

These are things to look into. Richen the idle mmixture slightly. Richen the mid range mixture. The engine can operate above the published WOT egt limit at lower power settings.

Hirth has a good fuel enjection system. I would look to reinstall the fuel injection and get it operating correctly.
