I stalling helicoils

[Speedbumpauto]

If it's me I use red. It's more permanent and viscous and you don't want those coils to come out. Some might use blue since, if you ever did want to remove the coils, it would be easier. Heli-coils will work fine, the web site is just info for future repair considerations. Another thing to do after the coil installation is make sure the carb base for the float bowl attachment is flat. They have an annoying habit of "pooching out" at the corners, usually because we are all guilty of overtightening the screws. I take a file and wrap it with some 320 or so grit sand paper and draw it across the flange of the carb. You will see shiney spots appear at the corners if it's not flat. If it's really bad, you can start with the file alone to remove material faster then finish with the paper. If you're lucky it will be almost flat when you start. Clean up after the operation with air and/or brake clean by squirting from the passages inside the carb to the flange so any junk is blown out of the flange before assembly.
Good Luck.
