Most kits are 'generic' so this is the best time to pick out the part that matches the removed part and set the residual parts aside."'' ^3''</blockquote>'' | :''<blockquote>"As a technique, I use two pans and label each "bin" and place the old part in one bin and at the same time, I place the new part in the other pan.

| + | <blockquote>''"That nut on the backside of the carburetor base plate, do not overtighten it. Use a thread sealant tape or paste on it and don't wrench down hard on it, the casting is thin and will crack if over torqued. you can pretty much get it tight by feel, the sealant allows you to tighten it with less torque and still have a good seal." ^''</blockquote> | ||
