[FC] Poor MPG and performance

[N2VZD at aol.com]

try larger main jets...i went thru that once , went up 2 notches and things 
 were much better.
install a vac gauge to see the radical difference.  more vac at  cruise  = 
better mileage and performance...
another thing to check is mechanical advance in distributor...make sure  
weights are in properly (found backwards weights in a rebuilt once). timing  
light will show this as timing retarding when you rev it up instead of  
advancing.
good luck 
regards , Tim Colson  
 63 rampy  @20 MPG and running great .   performing  good on thruway at 
65-70  but could use a touch more poop on entrance  ramps..
.053 jets   95 (9889)  cam   140 heads with 2  carbs , 030 oversize, 
powerglide ,with 3:27 differential, dual 140 logs  etc.
wish  i had put the 9891 cam in it...

I  have no problem getting performance out of the engines in my Yenko's. My 
63  Corvair 95, A hole other story. I have a 65, 95 HP, PG, 3.55.  I just  
rebuild it. Cam, cyl, pistons, balanced, and rings. I can get it to 60 MPH  
down hill as long as I have a good tall wind. 9 to 10 MPG's. MPG's were bad  
before I went through the engine. It starts and runs so smooth. I know the  
things that normally cause such problem's. I need some input from simple  
stupid to off the wall crazy. I love 95HP engines. I want that joy in this
