RE: DL-50 engine
I ask because I have a DL 50 that is hard to start when cold and almost impossible to re-start after it has been flown a couple of time in a day.
After it pops with the choke on, I open the choke with throttle trim set high and flip 20 - 30 times and all I can get out of it is short bursts of 2 - 3 seconds of run time. Choke and flip and flip and choke etc..... It even back fires often when trying to get it started.
CM6 gaped at .020
Walbro WT 751 with screen cleaned and both needles set to 1.5 turns out.
Once it starts it seems to run OK. This past weekend I got three flights out of it with the high end running rich enough to burble. I leaned the high end between each flight. On the fourth flight it wouldn't start after many flips of the prop. Pulled the plug and it was soaked. Replaced with another plug and finally got it started by opening the throttle up to more than 1/4.
Just wondering if this sounded like the ignition may be out of time.
I guess I should mention, this is not my only gasser. Zenoah G23, DL-30 and BME-116 all running and starting just fine.
Any suggestions?
