If it ran three months ago, I would start by doing a quick and easy carb clean as well as putting some fresh gas in the tank with dry gas. If it ran three months ago and was a daily driver, then it shouldnt need much at all! My car was a driver, then sat for some time. Sat motionless durring the winter until I went to look at it. he had charged the battery and cranker her over. Startright up and I have put on around 400 miles on mine already. Only has about 75,000 miles on it in the last 34 years, so you know it has sat many times in its life! Go to the home page and do a search for rebuilding car. I am sure there must be something around here on the carb to help you figure out how to do a simple clean and if need be, a rebuild. The rebuild kit I think should still be available at your local parts store? I know mine is! Glad to hear that it did crank over for you!
