I was not trying to put the motor on upside dowm I was trying to get the carb level. I just got me a dAX RT carb i was having clearance problems trying to got it on right due to my seat post I.I have a Raw66cc motor,I figured out I could shorten my intake a 1/4 inch and it would work.so I did and it worked,but the air filter wouldn't fit so I took the round black foam filter from my old carb and put it on the carb and it seems to work fine.I will take some pictures today to show everyone.thanks for all the great advice,Barryd
