Flathead Questions?

[FlatAddict]

1. Will a dual carb 255 Merc Flathead run on 6 volt? or at least fire or sputter?

2. Will a dual carbed 255 Merc Flathead running 6 volt produce a low compression number?

1. yes it will run on 6v. Though why not upgrade to 12v and put in a decent high output 12v coil to give you better fire in the hole.
2. 6v will not affect compression at all, though 12v will give better starting .

If you want 6v carry on as is.

the trick with 6v is grounds, lots of good clean grounds with a heavy battery cable, not the 12v thin kind, from batt to engine, from engine to frame, from engine to fire wall, and a good heavy wire from engine to a clean starter bolt, try not to use an exhaust manafold bolt as a ground , heat is the enemy of electricity, the hotter it is the less juice will flow

Your bigest problem is the distributor, the stock distributor doesn't work well with dual carbs.

1. No
2. No

Neither question has anything to do with voltage.
