IH-200 Condensor:
I am curious if a IH-200 tractor condensor from NAPA will work on a 1952 F-1 239 flathead.Would this possibly help on the hot starting problem I have always had?I was wondering if it will mount inside the distributor cap like the standard one?

The condenser value isn't super critical, though they are sized for the coil in use. Usually about .2uF, so anything that will fit is likely to work OK.
Why don't you use a proper replacement, tho?

I thought maybe this condensor would maybe provide more power to the points for cranking when everything is hot!Once everything is hot my truck has always been hard to start.It turns over good ,but don't seem to have the voltage after things get hot.It cranks excellent when cold.When it is hot and sits off for about 15 to 20 min, I get the hard to start.

On a 6v system, it is critical to get a 6v condenser. I doubt the condenser is a hot start issue, they either work or don't. Are your points burning?
Here's a great explanation from "Bubba" who is the distributor guru.

They absolutely need to be tested when at normal operating temperature, because that is the failure mode. Most people don't bother to test them, but replace with new, or known good. Coils are the same way, shorted turns in the secondary, it will run but not very well under load at normal operating temps.
Any capacitor with the proper voltage rating and capacitance should work? There is a little "tuning" involved based on the exact coil specs so far as replacement/selection but so long as the capacitance and voltage spec is close it will work just fine.

1948/55 is 6V, 1956 and later is 12V. Condenser (12300) is the same for both, but is specific to I-6 or V8.

That's because FORD 12v ignition systems essentially used a 6v coil with a ballast resistor to create a 12v system. So a Ford OEM condenser would be OK for either, but a generic 12v condenser will have about 50% less capacitance than a 6v. Typical (NON-FORD) 12v condenser spec is .25 Mfd, Ford 6v spec is .35 Mfd. So the Ford condenser B7A-12230-A is a 6v condenser.

The takeaway is to install one that is the same capacitance specified in the manual for the stock coil (or whatever coil used) as this is tuned for resonance. The _voltage_ rating of any automotive condensor is way higher than simply a six or twelve volts nominal. Too little capacitance might roast points, or poor performance under load?
