Hi all,
I have a frankenmerc that I need some help with. I dont know for sure what it is. It is a reman block, plastic plug says 175. the heads are marked 15221 c2. Three Wh 46 carbs, black coated stator. Olive green 94 tooth flywheel, rectifier only, NO Regulator. And lastly a square pump with oil injection.
Now, on to my problem. The motor runs and idles fine on the muffs, doesn't run on the water unless started in neutral with a fully advanced throttle. I discovered that there is back pressure on the water and not on muffs which could be why it runs on muffs. It has new plugs, new impeller, a pair of new mallory 9-25100 switchboxes and a new fuel pump.
Squeezing the bulb on both muffs and water has no noticeable affect. So, I suspect timing is off. There are zero advance modules, or idle stabilizers. Can someone tell me what motor I have and the proper procedure for said motor? I know the guys here are just,as good or better than merc techs!
