Excellent series on rebuilding an OMC carb. It helped me rebuild one on my 1970 6hp Johnson motor I got with my sailboat. I had trouble finding the limited clearance bit he referenced. I found at Lowes a 3/16" Cabinet Tip 4 " Screwdriver made by Southwire Co for $9.00. It wasn't with the regular screwdrivers, I found it in the hardware aisle with nuts bolts and screws. It worked great!

I took a old nail the same width as the opening. and grinded it down on a wheel to be like a flat head. then I bent it in a vice 90 degree so I have leverage to unscrew the orifice.. worked great..

Do you have a video on how to lean the low speed needle? I have a 68 6 HP is smoke a lot I think it's to rich. How do I lean it without leaning to much?
