W.H.Mullins Company of Salem ,Ohio was a metal stamping Co.and mfgrd many kinds of products one was thier well known metal boats. over the years they contracted with several different Engine mfgrs and put the mullins tag on them. if you could post some photos of the cylinder, flywheel, waterpump etc could ID your engine and get some info about it !

Hi Dave,
The ignition is based on a low voltage connection ( 12V) to the timer, which then fires a high voltage buzz coil.
The buzz coil's are quite straightforward to build.
I can send you the diagrams and a typical connection diagram for the low voltage part.
You can get my email from my profile - just click on my name on the left

Thaks Miro the ignition system makes sense, What I am looking for is a possible manual on the Roberts also I need some guidance on the oiling system and why there are crank case drains? |

The smaller gearbox does not have a name on it, it also has the same size shaft hole as the engine and the set screws which are offset line up with the saft on the engine.The bigger one has a larger shaft.Not sure what the larger one came off? Keep the info comming I am learning alot.

The crankcase drains are there just to do that - drain the crankcase.
Sometimes, the crankcase will load up with gas and it becomes almost impossible to start (mixture far too rich) - so - you open the drains and empty the crankcase.
As for the oiling system, gas/oil mix is what MUST be used. The drip oilers, while historically correct, aren't nearly as good as the gas/oil mix for lubrication.
You can set them up and if you really want to, have them drip oil ( 1 drip every second or two)
but turn them off several minutes before you stop the engine.
Residual oil in the engine will contribute to build up of carbon on the rings.

The smaller reverse gear sitting between the beds is a Joe's Gear by Snow & Petrelli. If you scrub the top of the flat bar shift lever, you'll find some information stamped in there; if it's the original handle.
There is at least one thread on these gears if you do a search of this site. |

I could tackle it possibly I have a pattern right next to it on the other rod.I also have a mill and lathe, it would be a good project. It would be easier if I could find one.Thanks John you always have good comments on subjects.

Seconded!
Are you going to put one of the reverse gears on as well?
I'm curious about that De Lavigne oiler sitting on an angle; was there a reason for that? |

Yes the engine sets in the boat at an angle to line up with the prop shaft, when mounted the oiler is straight up and down. |
