hey, i am new to this forum and really glad to be a part of this community! I just got a 1970 Ct-90 and having some start-up trouble. i replaced the spark plug-got some good blue sparks. i also charged the battery and got a bright green neutral light, headlight works on the hibeam mode, and horn works. i took out the carb and sprayed it down with crab cleaner, but didnt know how to clean orfices. i am just stuck on what to do, supposely it isnt a hard bike to work on and the owner used it two monthes ago. we also replaced the lines that feed the carb fuel, so that's good. it just tries to start but wont fully engage. any tips or advice is greatly appreciated. the owner suggested cleaning the carb orfices, so i guess that will be needed. i am really eager to this up and running, i got it last weekend for my brithday, so im really excited.
