Onan Generaor - 10 yr old

my onan has and electric choke pull off (1977) the newer ones have a vacuum pull off, i had to rebuild the carb for ours last year it did run , but was a bit hard starting at times. I had picked up a can of industrial carb cleaner and soaked all the metal parts in it , (no plastic or rubber) as this cleaner will remove the paint and eat anything not metal. i also added an extra inline fuel filter with a clear case as i know there is junk in my main fuel tanks as i have not had a chance to drop them and have them steam cleaned as yet. there is really not too much too the carbs and the orifices are quite small so a little bit of crud messes them up. I also found that the previous owner had put the choke pull off spring in incorrect so as it heated up it would give it more choke instead of taking it off..
