I am currently restoring and rebuilding a ford 640 that I bought with a wagner loader. The motor was ceased when i bought it.
For the engine rebuild it needed new sleeves and pistons. I had bought a sleeve and piston sets, one set per cylinder. At the time of buying them the the high compression piston sets were only $2 more than the standard set. As of current time having the tractor completely rebuilt and restored the total $8 I spent to have a more power full tractor has been the most headache including $8 I've ever spent
Here the kits I used: item number 160840 on yesterday tractors website. Nearly $100 a kit now but only about $50 when I bought them back in January 2023.
Everything I've done to the motor: had the block blasted and cooked. I then resleeved the motor my self. Then sent it to a machinist who honed the cylinders because they shrank a little, and also decked the block and the head about a total of .023" off both combined. I replaced everything that the motor contains other than the cracked, cam, and rod.
NOW HERES MY ISSUE:
The motor does not want to start. I contacted the manufacturer of the pistons, Reliance power parts, and was told the high compression pistons run on factor ford motor setting. That was not working for me, I new it wasn't going to work as I'm adding compression. Originally when I cranked it over it would have no effort of starting, have spark and fuel, the exhaust would spit vaporized gas. Started playing with timing, dropped it from 8 degrees timed then up to 20 degrees in 2 degree increments then dropped it back down to 15 degrees timed as that sounded the best. When I crank the motor on the starter the cylinders will pop now, but not every cylinder will pop in every combustion set. It will also have an occasional back fire. The little combustion that it does have isn't very strong but that is also only on the starter, motor doesn't run by its self. You might think it's a carb thing but it's not, motor gets fuel. I've messed with the needles and nothing gets better. Messing with the needles shouldn't have anything to do with a motor starting, there only there for idle control.
I recently started playing with valve last. I brought it down from the recommended .014 to .016 range down to .010 the up to .025 range, still nothing and doesn't even want to make as much popping sounds.
MY QUESTION TO ALL OF YOU
Is there anyone out there that have used high compression pistons on there mid to last 50s ford tractors
And is there anyone that would know the motor setting that the tractors need to run.
I know there's 2 factors for me, I have high compression pistons and I've reduced the block and head making a little more compression.
I'm on a few Facebook groups and the only "glorified" answer I've gotten from people is " your electronics are bad" and "your distributor is 180 out". There not, I've checked
I've been working on starting this motor for 2-3 hours a day for the last 3 months, I'm starting to feel very defeated. Not a good feeling for my first serious motor build.
