The Stupid Question Thread

[mark tucker]

stupid question...why is there a general parts category and a high performance category? are old rusty tins really high performance? what about 40 hp intake gaskets? or old dead stock wore out distributors? or stock rocker arms? in the first 2 pages of high performance parts about 90% are old stock wore out crap. do they think is they put it in the general parts we will know it's old wore out crap? yes I know that's more than 1 stupid question....but what else do I have to ask a stupid question about stupid people Shocked Confused ...tere Im done....for now Wink

Would using higher octane fuel cause an increase in stop-sign stalls?
Daughter read the fuel door (which says to use 91 octane) and so rounded up to 93 (which is available here, but not 91) and then noticed that engine started occasionally stalling while in neutral and the car is stopped for a moment at a stop sign.

If higher-octane fuel can withstand more pressure before igniting, then perhaps at low RPM, it just doesn't ignite? No, it's the spark plugs that ignite the fuel, right? (That's why this is in the Stupid Question Thread.)

in a spark-ignition engine you can safely use any fuel with an octane number higher than the mimimum recommended by the manufacturer without consequences, either positive or negative. On the other hand, if you go lower, you'll experience detonation (pre-ignition) or dieseling (engine running after shutoff due to residual heat), and that's definitely on the bad side.

that's for the octane number theory.

now what can happen when using a "modern" gasoline in an older car, is that the additives used to increase the octane number (no more TEL unfortunately ) or, if present, the ethanol mixed in in the gas, will soften old gums and varnishes present in the fuel system and bring them straight to the carburettor, where they may obstruct passages and jets, resulting in a worse idle.

I'd rather clean the carb and put a fuel filter along the line from the tank to the pump.

Has anyone had luck restoring a late super beetle sun visor? Aftermarket visors aren't sold for curved windshield hardtop supers and I'm trying to figure out if there's a way without destroying it.

My beetle won't start, its a 75 fuel injection. it turns over 3 times but won't catch. after 3 times it won't start and you have to wait awhile to do it again.

I changed an outer CV boot, put the car away, cleared up all the tools, jack etc and noticed that I've left out a concave washer (it was stuck in the old boot).

Before I get everything out and tear it all down again, how critical is that washer? I'm just trying to avoid pissing myself off too much by doing something that's not strictly necessary.

It's No.9 in the diagram below.

I believe it's very important, since that's a location that endures some serious stress and pressures as power is transferred to the wheels. Just my 2c.

To be more specific, the concave washer preloads the axle to the CV joint center to prevent the axle sliding in and out of the CV, thus wearing the axle and joint splines or possibly popping the circlip (11) off. It is basically a Belleville washer.

Done! The circlip is just slightly harder to get on now so preloaded, yep.

Not sure how the racers fare with their deleted circlips and machined off shoulders but for mine it makes sense to keep it stock.

Thanks again!
