Get a manual and read,read and read it again.When you are relaxed and confident go after it,look at the way things go,take pix with you phone how cables and wiring goes.Altho it's obvious when it comes time to reassemble.Use the right tool for the job,remain calm and observant,keep you eyes open for the small parts that will jump out at you then hide under the bench.Use the calculator on here.IF all fails I 'll sell you a set of stock carbs. good luck.
