after all the hard work 'turn in n out of the reg' to try to get the engine to run , it seems like need to richen the reg by 1/4 to let the engine to run right .......

Now the engine is running , and strating the engine is easy now !! No 'Kicking' now . I have run 3 full tank now '600cc tank' with 1/4 thorttle stick , the engine run with out cut ...

smooth running .... will try half throttle n full thorttle after another 2 full tank n see how the engine run .

Thanks for all the advice . Will follow up the report how the engine run .
