I am going through the carbs on the 79 srx I just purchased, it is all stock and has the stock 36 powerjets with 340main jets . My question is how much does the powerjet vary the main jetting and at what powerjet dial setting is it actually 340. I have 38 and 44 and possibly can get some 40 non powerjet roundslides I could put on it but would like to run it with the stock carbs to get a baseline. Thanks for any help
