I have changed pistons in my engine now and is done, head is on place and everything.
BUT now i saw in the joyner service manual that it was important that the connecting rods was installed "the right way" (D. When installing piston and connecting rod assembly into cylinders. The marked surfaces of the
connecting rod and piston must face the front of engine (fig.3-10).)
The pistons is correctly installed but when i installed the connecting rods i couldnt see any difference from side to side so i just put them back in and now one of them is "rotated" 180 degree if i looked at the texts on them.
So, does it matter? Is the manual a little bit "universal" or it is important? Has it to do with some oil lubrication? The only thing i noticed when i intstalled them was the bearing shell that has to be put back right so the notch goes in to the groove.
Anyone has any good answear to this?
Not sure I'm explaining that right. but,.. I'll start with some history. I bought the 4x4 4010 mule with a bad motor. I built the engine. Bottom end up. Fresh bearings, Pistons, etc. Cranks up and runs with no issues. However,.. doesn't seem to run faster than 20 mph and pulses at top speed like something is up with the governor. It feels like its cutting back. Climbing and pulling it seems to be fine,. It pulls hard and doesn't cut up. But on the road flat out Cuts back/Chugs/pulses/Revs.
Not sure where to start. Kinda tired of thinking about it. Any Ideas?
Just a mention, I'm not trying to make it faster, just fixed. 25mph it good by me. Hell,... for my purposes I'm fine with 20 mph as long as its' running properly.
