Another carb problem with 50 NG
After flying 2 to 4 times the engine suddenly becomes imposible to start. It ussually starts after fliping the prop with choke on, on the third or fourth flip. However, it fies good for say one sunday, four to six flights, and then the next sunday it will only give two flights and then it wont start. The first time it happened, I took it back home and took the carb out and cleaned it, there was no dirt in it. so I took the spark plug out and there was a little carbon build up on the element. I cleaned it and put everything on the engine again. The engine worked fine for about 8 flights. 6 of them right after the cleanup and the other two just yesterday. After the second flight yesterday, again the engine would not start. What could the problem be?
The engine is on an Aviation models (TOC1) YAK 54, the cowling is baffled so the only opening is where the cilinder is, spinning a Bambula 20x10 at 7260 rpms with a supersonic muffler. NiMh battery for the ignition 4.8volts at 2000mAh.
Any advice on the problem Mike?
