Over filling a clone

raydhd

In my quest for other idiots that like engine testing on youtube I found someone who had put a clear front piece on a B&S oppie to observe splash oiling in action.He showed that overfilling the oppies by some amount seemed to keep the upper crankpin much better oiled.My first plama cutter creation was an extender to move the S/G futher from the engine and use an ax32 belt.Now I can actually use the dip stick.Well the idea over over filling the splash oiling clone kicked in.So I filled the clone until oil was just trickling out the dip stick hole.I started it,idled it ,sped it, and drove it for quite a bit.I have not noticed any smoking or any oil coming out of the breather or any other negative results.One positive result is the clone is now whisper quiet noise wise.ANY thoughts small engine wizards??? Am I asking for trouble??

Only thing I can think of is aerating the oil. In other words causing it to foam and then you'll have all sorts of issues. My buddy that raced clones actually used to underfill them. I think they are supposed to take 38 ounces, or just over a quart. He would run just over a half quart. But his oil was also $50/gallon and they changed it every Sunday morning after the Saturday night races.

Yes. Too much oil is worse than too little oil. Street has described one significant issue. Another issue is if enough oil is allowed to pass by the rings, and it will in time, it will get into the combustion chamber and hydraulic the motor. It will be too late before you even notice it. Too much oil also robs a lot of power.

It certain appears to take some power away.But I am not talking vastly over filling only slightly over filling.On the aeration thing is no pump to cavitate and lose oil pressure.Also with my 24" tires in the back and 20" tires up front there is a certain amount of tilt to the dip stick side.Stay tuned.

Ray, I predict that overfilling will be a several-hundred dollar mistake. It's your motor, take your chances.

Friday I will jack up the cart until it is level and then check where the actual oil level is.

Just one more part to my off the wall thinking.In lawn mower or pressure washer or generator the sump is more or less stationary.In these hopped up golf carts we have acceleration,turns under some g-forces,braking,and rpms going up and down.So you would think the actual oil level in the rod bearing and camshaft and lifter area has to vary quite a bit, and with the off roaders I would guess these conditions are even more severe.

I know there is no oil pump. But the only part usually touching the oil is the dipper on the connecting rod. Too much and the crank throw will be dipping into it and cause the aeration.

I know you are probably right,but it really bothers me how much quieter the engine is.Some thing that was making that typical clone noise is now quiet.Is it the lifters,compression release,gears driving the balance and cam shafts,the bushings these ride in,or the connecting rod itself?Did I merely change the harmonics of the crankcase.Vegascarts has you fill the crankcase thru that back plug until it over flows because the dipstick is blocked and the handle cut down to clear the S/G.But by extending the S/G bracket and adding a longer belt the dipstick is now useable.I then noticed the dip stick hole sits higher on the crankcase than the other port.My cart with its 70's hot rod rake furthers the idea that perhaps I have been under oiled all along.As I said earlier friday I will jack up the cart to a level position and see where I really am oil wise.

I'm intrigued by the quieting effect too...

I think you should cut a hole in the crankcase and put a window in..

C'mon... One for the team
