The new ignition I have is sold as a replacement for the old style ignition. I tried my 13 year old ignition and it works exactly the same as the new.

I bought a new carb for it, but have not been able to get it to run with the old or the new carb.

I use the 3W starting instructions ..... propping it 10 to 12 times with full throttle and choke closed - ignition off. Then turn on ignition and flip the prop till it pops. (All good to this point) Then open the choke and flip and flip and flip and flip...and flip some more with an occasional pop. It almost sounds like a backfire thus leading me to check the timing.


The weird part is that I have started this engine several times over the last month with no issues and have flown the model 3 flights (on 3 separate days). On two occasions I have flown the model successfully and then fueled it for a second flight. Both days I was unable to start it for the second flight. The first time this happened is when I decided to replace the ignition module. The second time this happened was with the new ignition module installed. That’s when I ordered the new sensor and magnet. I replaced the magnet and the sensor but the new sensor doesn’t seem to work as well as the old one.
Going to go get some new spark plugs today and try to get the timing as close as I can to 27 degrees. Maybe I’ll get lucky.
