Re: [T3] Summer Questions (long)

Usually, it occurs at the speeds where i am in second or third gears, so 
between 20-35 mph or so.

That is possible, could you give me more information on how to check this 
out?

Oh yeah, i know i've set the timing properly, although to do so, i had to go 
to some awefully wierd measures to get that set corectly, but yes, i 
followed the procedure outlined in the Bentley Manual, and it is timed 
correctly, and the advance mechanisms work correctly.

I don't think my clutch is slipping, because i'll get the noise with a 
strong cross wind too, and i've heard from a few others on the list that the 
same thing happens to them too, so, who knows?

See, money is no problem as far as gas goes, i can spare the extra ten cents 
a gallon for the premium (hi octane) stuff, i am just curious if the high 
octane gas can cause any harm.  Cause once i was talkin to an old red neck 
chevy mechanic around here, and he was tellin me this story about some kid 
who got a hold of a '72 Super Beetle and ran high octane gas in it and blew 
the heads off.  Is that possible?  Can running High Octane gas on a stock 
'72 VW cause damage?

I live in Kokomo, Indiana, it's about 50 miles due north of Indianapolis on 
US 31.  If you will be traveling near here, tell me, where will you be 
going?

Thank you,

Jacob Schroeder
'72 Square
