<div>Thanks for the help folks!

JimmySkids, thanks for the detailed explanation. The motor is mounted inverted with the arm pointing towards the head. Since the firewall is so long it was hard to get a good angle to look at the carb intake without removing the engine, Ieven tried a little mirror! Using the little mirror Ithought Isaw it opening when Ipulled the arm back but Iwanted to confirm. Anyway, It looks like pushing the arm towards the prop closes the throttle and pulling it back opens it. This just seemed counterintuitive and Iwanted to for a second opinion!

Thanks, you all are great!</div>
