my first engine rebuild (318) advises

I have 1 year old carb, summit brand 600cfm, not going to change it for now, it works well and gets decent mpg on current comp. i will be using o2 sensor to tune it after rebuild.

fuel here is 95 or 98 oct, it says that it is... 95 has 10% alcohol and 98 has 5%.
i will be using 98 its not so much more expensive than 95
98 is 1.71€/L
95 is 1.65€/L

i will be getting my ''new'' a500 trans soon. So thats my first thing to check and see if it needs rebuilding.
guy hwo is selling it has receipt from 2002 when he rebuilded trans in local shop and bought new torque converter.

Last month of driving this summer till i put duster in garage and start rebuild
