been driving my sam very little since i got the tranny in, been doing some little things to it. but when i drive runs ok for a while, but when i hit 4th or so it begins bogging down and sometimes in 3rd. ok in 1st and 2nd what could it be vac advance? carb? any suggestions?
The bogging down you mention could be the very common "flat spot" many Zuk owners experience. The fix is easy. We sell a Suzuki factory part designed to eliminate the flat spot. it is a venturi tube designed to reduce turbulanec on air flow into the chamber. We order them in special from Suzuki since most delaerships have no clue about this part much less know how to even find the part number.
