First of all, I would like to thank you all for all the input !!!

I bought this engine from Rusty. It came with the perry pump amd MC carb. The standard pump has been off. He gave me a good deal for the whole thing (engine, pipe, header and bunch of acces.).

I hope I can run the exact same setting as he did. However, the engine is a bit far from the perry pump when it sitting on my plane. So, I replace the pressure tube with a similar dia. silicon tube. ( this could be the one of the cause) It ends up flooded all the time. Then, I start to screw out the hex adjustment screw ( it is about 5 turns out) of the pump. The flood is reduced after that. I was following the post on the centeral hobbies and the mc instruction and was trying to match the mark on the mixture arm and the location A . It flood badly. It was not working. Then, I start to move the mark on the mixture arm clock wise way pass the location A as the MC manual indicated to lean it. It ends up wiht almost 30-40 degree pass A. However, the engine can be started and idling for a long time without stop. I am using two HS-55 servo with larger servo arm which come with the servo. I setup the mixture linkage on the farthest hole on the servo arm, while for the throttle arm, it is in at one hole closer to the center of the servo. I follow the instruction from the Central hobbies post.

I believe it is a decent engine from Rusty, just my experience is limited for this kind of the set up. I would like to know how you guys setup the mixture curve from point to point. I throttle up (from 1st point ) by one click and one click and then pose to see if the engine can stay run or die. If the engine die then I try to lean it a bit and start it overall again. If it last longer, I keep going to lean it. It it reverse, I will go ricker. Man. It is about 50 degree now in michigan these few days. I do not know how much patience I have had left... The way I did definitely might sounds stupid to you. But I would like to learn the right way from you guys. Thanks so much
Man, it is cold. Got to have something like moonshine now..
