G 20 engine help
 

Hi guys,
I have a G 20 super tiger engine. I messed up the low mixture control valve. I closed it all the way and do not know how much to open it. If anyone can tell me how much to open it I would really appreciate it. Thanks!

You'll have to retune because the optimal setting is different for each engine. Start with 1 1/2 turns out and see what that gets you.

Get a long piece of full tubing on the fuel nipple. open the carb about 1/8th,. blow into the fuel tubing and open the needle bit by bit until you can just hear the air coming through the carb. Now open the needle 1/8th of a turn more. That will give you a starting setting that the engine should run on.

The main needle should be screwed in while you do this.
