U20 Flywheel bolts....washer or no washer? What if Aluminum Flywheel?
1st time with a U20 crank.......likely last as I don't plan for anymore.....

I use wavelock washers on mine.

I'm not familiar with those.

but what difference do the wavelock washers make to the torque values

With washers added, any kind, it would effectively decrease the recommended torque. The reason being is that it acts as a slip mechanism under the screw head, which will allow the bolt to reach yield easier. W/O washers, you need a higher screw torque to overcome the friction of the bolt head on the material beneath it.

With items like grease, anti-seize, and loctite, generally the bolt torque is 80% what it would normally be w/o a lubricant.

Thanks Phil. Now I know what they're called. I'm starting another project in SA up by TPC parkway and 281. You still working nights?
I'll probably be down there in a couple of weeks.

After driving for only 15 minutes or so the idle drops about 100-150 rpm, down into the 500s. Is this as simple as the idle adjust screws slipping? (They don't appear to be...) Or could this be a symptom of something more involved?

Do you have slack in your throttle cable? Usually when it gets hotter, the cable tightens, and causes increased RPM, but it is possible it's just a little snug or something. Otherwise do you use the choke, and could it be sticky until it warms up? Are your intake nuts/bolts tight, carb securing bolts tight? Sounds like something expanding with heat maybe?

[Gregs672000]

If it is running rich it may tend to bog down once the engine is warmed up, so check your tail pipe for dark exhaust, and check your plugs too. Nothing wrong with setting idle at about 1000 rpms so if it settles it's about 800 or so.

fuel level sender - does it matter on the orientation in the fuel tank or can it just be 'installed' in any position?

- tried testing it using a continuity/resitance meter and got no change - any better way to test?

Mine does the same thing. I've never solved it. And then if I blip the throttle, it will stumble and sometimes die. As someone else mentioned, I just set the idle a little higher so it doesn't settle down as far.

How different are the splines on the top of the early v late steering columns? Will an early steering wheel fit on a late column? Thanks
