RCGF 15cc will not run!
Hi guys,
Need help with my new RCGF 15cc engine. After 2 flights It all of a sudden will not transition from idle to full power. The engine dies as soon as I add power. I ran two tanks through the engine on a test stand with out a problem. I then mounted it to my Big Stick 60. I maiden the plane today. First flight went perfect with no issues. About 5 min into my second flight I could hear the engine tone change so I landed and killed the engine. I refueled and put it on the test stand and I figured I need to adjust the High end. Well I could not get it restarted. The engine would fire up for about 3 seconds and quit. After messing around with low end needle I finally got it to start and stay running but as soon as I advance the throttle it quits! Every time. I spent an hour playing with the needles with no luck. I reset the needles to the factory position as per the user manual and nothing works! I really feel stuck. I used new clean fuel but I didn't have a filter on my gas line in the plane. I took the pump plate off the carb and the filter was clear. However the screw holding the pump plate in place was not very tight and I wonder if this is the reason. I discovered this when I got home. Any ideas? And thinks in advance
Key points:
A: I ran two tanks ( 20 oz in total ) on a test stand and it ran as it should with a nice idle and no hesitation to full power. Engine has seen about 40 oz of fuel all together.
B: I am running mineral 2 stroke oil at 25:1 with a 91 octane gasoline.
C: I have tried the default spark plug as well as a Honda CM-6 with the same results.
D. There is no bubbles in the fuel line.
E: No fuel line filter however the filter on the carb pump was clear.

The battery is fine. I tested it and was still at 6.1 volts. I think I solved the problem but I have to wait for a replacement part to arrive to be 100%. the reed block is missing the flapper. I took the cylinder off the engine and found parts of the flapper in the engine. Obviously it broke off and was sucked in. I cleaned out the engine and put it all back together. Just ordered a new reed block.

That will do it. Hopefully you havent scored your piston or cylinder. If you have contact RCGF and maybe they will give you a new engine. They gave me one after mine seized the lower rod bearing

i don't have any faith in HK customer service! I purchased this engine 3 years ago and when it arrived the plastic fuel nipple on the carb was broken off. Long story short they did nothing to help and suggested I fix it ( Impossible as it is built in ) and I had to order a new carb at my own expense.
