See if a #10 or #8 machine thread works. It is one of these, but I don't remember which. I always buy new bolts and lock washers from the hardware store for carb top covers. You can buy stainless. And it doesn't cost as much.</div>

My friend had metric size bolts holding his carb tops on his TR8. I suspect that was because a previous owner put them in because they were close in size and he just forced them in because they were into aluminum.</div>

What are you referring to for damper 0-rings? If you are referring to the tiny one at the bottom of the dashpot that holds the dashpot oil around the metering needle, then yes that is a standard size o-ring that you can buy. The o-ring around the fuel reservoir
plug is standard and can be bought too.</div>

<div><font size="2">I worked on the carbs on my 1976 TR6 this weekend, one of the needle adjustments screws moved and I was able to lean the carb I needed for some improvement. A couple of questions, does anyone know the specs on the screws holding the top
cover to the body of the carb? Someone (not me - honest) buggered them up and I had to cut a slot on one to back it out. I would like to just replace them all. Moss has them at $1.89 apiece but that seems a bit much. I had a couple of screws in my loose
screw bin that looked correct but did not seem to fully thread into the carb body and I didn't want to force them and ruin the threads. Also, if the damper o-rings are a standard size that I can pick up at a local FLAPS instead of ordering them, i would appreciate
knowing the specs on those as well. <br>
