I have this 83 model 185s that has had a hard life and am resurrecting it slowly. The thing would never idle properly but ran good otherwise. I talked to a bike mechanic and he said the problem is that the needle wears an oblong hole in the pressed guide. Well, we ordered the part from Honda ($39.00) and he installed the guide and I put the carb back together. Well, the thing idles beautiful now and has good response but bogs above 3/4 throttle. It feels too lean. My Clymer manual doesn't list this carb (PD85A) but the PD85C uses a 100 jet and I have a 98 jet in mine. Can anyone verify the correct jet size?
BTW: I had a problem with runaway idle speed the longer it idled. I found out that the throttle cable sits above the engine and when idling the heat goes straight up to the cable and apparently stretchs the outer casing more than the cable and it actually increases throttle speed sitting there! The cure it to make sure there is slack in the cable by screwing it in far enough into the carb top cap assembly.
