Magnet is strongly magnetized (not sure how to word that haha). Crank sensor seems ok, it has not been touched in any way. Same as it was prior to the issue.
However, ignition would be my next guess after carb and mixture. |

Chuck, Im curious if this is the DLE that Jedi worked on for you awhile back?
Your description seriously sounds like a bad ignition battery. Id really look at the simple obvious stuff, and I am sure you have. I wouldnt just go by a volt meter either, make certain you use one that will put a load on it. Id almost bet you have a weak cell that just drops volts in a hurry. or ignition is not sending a strong spark for some reason.. Plug cap dented in any way? Just seems ignition related one way or another. what was the battery you are using? Also, if you are using a regulator, and the battery is lower than what the regulator regulates at.. you will get trouble. just a couple random thoughts.. maybe no help at all, or already covered. if so, sorry to repeat, tryin to help. |

Battery is a 2 cell a123 through an IBEC. I will fully charge it and see. Plug cap does not appear to be dented.
First thing will be to run it with the cleaned carb. If that does it I foundy problem. If not, I will plug a battery straight into the ignition. And keep going one step at a time until I find the problem. |

Okay well i was able to dodge the rain and get out and run the engine. The cleaned carb did nothing. The same problem still existed. It would not want to go past half throttle. If I put the bottle up to just below half it would slowly lose RPMs and then die in about 10 to 15 seconds. The problem could not be tuned out. I went ± half turn on both needles and nothing helped. But I did find something very interesting. When I've richened the high-speed needle about a quarter return I was able to advance the throttle to about three quarters and it didn't want to stumble much. But it definitely was not running very well or at best Rpm's. The next band of rain was coming through so I started to pack up but I ran the engine as far advanced as it would let me and shut the ignition often so I could read the spark plug. It was a color I've never seen before. It was gray, almost white not extraordinarily white but just a little bit. It was definitely not oily and not brown, indicating a lean mixture.
So I have a new theory. Air leak. It would make sense: lean mixture and not able to solve it through tuning. PS I took the sparkplug out and put it in the boot and the spark was fine so the ignition seems to be okay. |

it not getting enough fuel.when you richen the high needle and it gets just a little better and the color of the plug tells you that.could be a fuel passage is clogged in carb.what ever it is its fuel related my next step would clean out the carb.when you look at the carb that will give you a chance to look at all the gaskets too.

I will get some carb cleaner and go through the cab again properly. Last time i made a beeline for the carb screen.
I'll also check for an air leak with the carb cleaner. |

Pull both needles out and spray carb cleaner through both holes and all other holes. Then use compressed air to blow them out again.

I shall. I am baffled as to what would cause such odd running. Im pretty sure it is fuel starvation, especially due to the plug.

Compression feels great to me. I started it about 6 times hot while fiddling with it today. Took a decent flip.
Not sure how much time. This is an engine which Jodi so so so graciously built for me last fall. It has ran like a top ever since until this week. If I remember correctly, it was pretty much new when I got it. So a good 10 gallons maybe? I flew throughout the winter with it. |

I don't think it to be a ring related issue then. Your are most likely having fuel restrictions or air leaks like others have already stated. Look good and hard at the complete induction system including cleaning the tiny holes in the carb by also pushing a tiny piece of steel wire through the holes to make shure any restriction is broke free. The induction system includes carb block, reed block, reed carrier, reeds and gaskets. Good luck with it. Maybe the Jedi will chime in too.

I have pm'd him and will do it again. He is a wealth of knowledge and is always happy to help I owe him more thanks than I could ever give in a lifetime.

and you are positive that all gaskets are installed correctly yes?,,, no gasket sealant where its not suppose to be right?--- meaning that one little hole,,, can t remember the name of it at the moment,,, has no KAA KAA in it right?(if that hole is partially blocked it will run like KAA KAA)

Don't push wire thur any holes in the carb. Not sound advice IMHO.
