The two tubes are all I don't see, the intake is above and to the right of the clutch assembly (with two aluminum tubes mounted on top of it). The mount if you will for the blower is attached to the blower on the right hand side, it's also the timing cover. Oops, didn't see second page, guess it's already figured out!! LOL Yeah the two tubes aren't shown in the pic from what I can see.. Love the vintage mills in that pic Robert!!!!!!!
