- Assuming that your needle valves are properly set:
- There are really only 3 possible things that can cause an engine to
- stop or lose a lot of rpm when you pull off the glow battery.
- 1. Too cold a glow plug.
- 2. Too cold a fuel or bad fuel contaminated with water. Cold fuel
- is equivalent to low or no nitromethane.
- 3. Low compression in the engine.

- I would do the following to solve your problem. First, change to a
- new fresh fuel of at least 10% nitro of a reputable brand or one that
- runs well in one of your friend's engines. If that doesn't fix it,
- then change to a hotter plug, e.g. a Fox R/C long idle bar plug or a
- Fox Miracle plug. If that doesn't fix it, check to see if your
- compression is good. Maybe you need a new ring or piston and liner
- if they are worn out or maybe you have a leaking head gasket.
