Heli-Coil

[SANTA Ray]

Probably spelled it wrong! I need to repair a Tilly carb mounting. I have never installed one of these. Is there any special tool or info I need??

you will need the tap and the insertion tool. Any friendly engine shop ought to do that for about free.

Heli coil should come as a "kit" with drill size etc. all included. Easy to do

You can find a kit with 3 inserts at you local autoparts store chain,

inserts, tap, tool, instructions included,

use a drill press if you have one as it is important to keep the drilled hole straight, if not, level the surface and do the best you can by eye,

good luck

I have seen a few Tilly carbs that the mounting threads were stripped and they had a longer bolt with a nut on it.

Go see the article on my club's website: http://www.CedarCreekAs.org Go to the TechTopics section and there's an article that did just exactly what you want.

I just had an idea on how you could accurately drill a hole perpendicular to a flat surface: Loosen the tilt adjustment of your drill press table and rotate it 180 degrees, so it is upside down. Then hold or clamp the carburetor flange up against the table surface and drill down into it.

Here is another idea (that I have actually done): to tap accurately, mount the tap in your drill press, and remove the belt. Then rotate the driven pully by hand to rotate the tap, as you gently lower it into the work.
