thanks Bruce, i did pinch test and at high-mid speed it will kill, at idle the rpms will increase a lil then kill. at this point i will take all the advice and stick with the fuel and try the han3001 plug that's suppose to be in there.

the engine is not that far off, the plane fly's great in the air even at a low speed coming in though just before it kills i hear the engine clakin then dead stick. it takes off great, it just doesn't want to idle coming in for a landing like it idles on the ground.

another factor that can be preventing it from idleing is the possibility i flared the low speed seat upon and improper setting and closing the throttle at one time.

thanks
