[QUOTE="Fred W, post: 1395124, member: 3828"] Ross, It wasnt that hard to get those ugly looking throttle plates clean by just spraying. The stuff that is caked up on them easily dissolves when sprayed with solvent. Dissassemble as little of the assembly as possible. If the high idle circuits are working now, dont F with them. My strong recommendation is to avoid using carb cleaner entirely. Counterintuitively, that stuff is too rough on internal rubber parts for use in an assembled throttle body ( or carb for that matter). Instead use brake cleaner spray. It is just as good at cleaning but wont soften the rubber bits. The job was tedious, but not difficult. The hardest thing was getting the throttle port boots fully reseated during reassembly [/QUOTE]
