Has anyone else had a problem with their BME 50 in regards to starting? My first three flights were flawless, the engine started and ran perfectly. The plane then sat for a few weeks and when I went to start it, nothing. I replaced the plug, still nothing. After two hours of piddling around, it went to the basement where it sat all summer (working on other projects); I got it out last week and it started third flip, ran up, then when I idled down it stalled out (probably not warmed up yet). Then, it wouldn't start. I am beyond frustrated. I called C&H Ignition, and they are "closed due to health reasons and should reopen Monday, September 20." I was talking with a guy last night and he said a buddy of his had the exact same problem I am having.

I have a 4.8V 1700 mah ignition pack and am using a MPI switch w/ charge jack.

Any suggestions???

Thanks,
Lance

I have this exact combination, BME 50 in the GP Wagstaff, and had the exact same problem as you. Turned out that after sitting for a while, the tubing inside the tank got so stiff the clunk wouldn't even move around anymore, and it was sucking air around where the tubing connects to the brass tube. So I replaced all the plumbing on the plane (just not to take any chance) and the engine ran fine afterwards.

I had a similar problem with my BME 50 It turned out to be a faulty ignition module or damage to the module from vibration. check the output voltage from the module. It should be the same as the input from the battery. CH ignition can always fix it. Make sure you have the module well padded to prevent vibration damage.

Gabriel:

Thanks for the heads up on the fuel tube in tank. I have the cowl off and can see that the engine is indeed getting gas.

Sedrick:

I have a feeling it is a fault in the ignition module. I will check it as you suggested and see what I can find.

Thanks,
Lance

I have the same problem, bme 50 DP Extra 330 L, in my case the sensor of the engine to the ignition fail. I live in Mexico and is very difficult shipping the engine to repair, check this is too weak.

Now I cant fly my extra for many weeks[&o][&o]

I had the same problem, intermittantly unable to start, due to a bad pulse switch (the little electronic part that faces the magnet in the crankshaft hub). If CH ignition cant be reached you might be able to get a replacement part from BME, but it would be best to talk to the fellow at CH on the phone so he can walk you through testing of your ignition system.
