About a dozen years ago i was talking with delco don about this 110v generator. He was unsure about the model. He said it could be a 1275, 6005 or a 312. How do i find out? It does not have a outside points cover. I assume its behind the flywheel like a maytag? Number shows its a 1923. The outlet bar was put on by the former owner about 1930. Iam getting ready to work on it. Would like input. Thanks.

Hi Dave,
I have a few Delcos, but by no means am I an authority. Don was one of the Delco gurus, another was/is Wayne Sphar, who kind of disappeared off the radar.
Wayne and Elms Bros. published an information chart for Delcos which list the 312 and 1275, but not the 6005 or any number close to that.
The chart lists only a few differences in those two models.
Major differences:
Mod.- 312, 5 hp, 3 3/4" bore, 6" stroke, oil cap. 15 pts.,115Volt 21.7 amps.
Mod 1275- 2 1/2 hp, 3" bore, 5" stroke, oil cap. 2 1/2 -3 1/2 qts., 115Volts, 10.8 Amps
The chart list Waynes Avella Pa. address and phone 412 345 3639
and Elm Bros Waynesburg Pa, 412 627 6038. I've had that list probably 25 years, good luck if you try to contact them.
I visited Waynes Delco museum a lot of years ago, pretty impressive collection. And I new Delco Don, mostly in Emails and met him when he made a trip to Coolspring not long before he died. Real nice guy. Never met the Elms Bros.

That's all the info I have,
GUS

I think that is the 1278 plant,

I had the 6005 engine only version, and that is the same, minus the armature and field coil casting. Giveaway is the fuel pump carb and speed control. Magneto armature is behind the flywheel, points are behind speed control I think?. Its been a number of years since I had it. It is still on my youtube vid page.

Thanks. Iam quite sure its a 1275. Its 110v and has its own flywheel magneto. This unit never used batteries. The power was generated and used from running the engine. My question now is im i supposted to have a condenser in the breaker points compartment? I do have a spark by rotating the flywheel but not a great one. Thanks.

That was a late night misstatement. I was supposed to say the condenser is behind the flywheel, it is a 1275.Sorry for the confusion.

The aluminum piston in this thing is 3 in. Someone put in new rings that were too thick. (they bottomed out in the lan bottom) and, one ring was an oil ring. There are no oil holes drilled for the oil ring. I assume its not supposted to have an oil ring? Thanks.
