Hello FolksI bought a old 1990 cr 125, I rebuilt the engine. But its got a nasty bog for a bottom end, Top end is fine. I took the carb apart and discovered the following, remember im not a carb expert. The Needle clip position was at the very top 1st position, Accoding to the manualThinking this was my problem i set it to 4th and i blew a plug.Stock accoding to my manual is 3rd clip positionThe air screw setting had no effect on the performance. Turn all the out, turn all the way in, middle same thing.Just boggedNow after ripping appart the Carb i found the standard main jet number is 182Stock accoding to the manual is 168 (Big Difference) The standard slow jet is 58, Which matches stock. I dont know how to mesure the float distance, so i cant tell you what its at So my question, is 182 jet causing my nightmares ?Do you have a instructions on how to mesure the float distance ?Also the Float valve has no number on it so im assuming their all the same ?645 feet above sea level.North Bay Ontario Canada, I googled that with success dont worry i had protection on
