PTO piston hole problem
I finally got the pto piston and stuff back on.
I took the carbs out and the pto carb looked like it had been leaking so I took it apart fun! fun! and the low speed jet was clogged and the diaphram was split and trashed looking. I hope this was the problem because I can't find anything else wrong. I just hope it will start after I put it all back together and not burn another piston.
Does the oil pump have a gasket. I was thinking about taking it off to make sure it's ok maybe put some grease in there or is thay a bad ideal.

Can you add the year and model with your post?
Old guys like me can't remember everybody's ride and I'd love to comment.

It's probably not a bad idea to replace the pump, it's been on that engine since 95-it won't last long.
It would be less expensive to go pre-mix but you would have to mix your oil/gas, some hate to do that.
Did you change all of the lines, fuel valve and install a 3 outlet pump or are you leaving it all stock?

Im replacing the fuel pump with a 780 fuel pump 3 outlet.
I ordered my fuel line off ebay from the Fuel Line Guy-"PURPLE RACING FAST FLOW FUEL LINE". But I dont know if its the good stuff.
I also got fuel filters and oil filter from partsland.
Can I remove the oil pump and put grease in there and reinstall or will I have to get a gasket or does it even have a gasket?

If I go premix what all would I have to do?
What do you do with the hoses running to the flame arrestor and the nipples coming out of the flame arrestor and wont I get low oil signal?

To go pre-mix you purchase an oil pump block off kit (I like the insert style)
Remove the pump and all lines to the carbs
Remove oil tank (you can leave it if you wish)
Remove the sender and install a 33 ohm resisitor in line or keep the gauge and zip tie the float UP and leave it in the oil tank.
Plug the nipples at the carbs (I like MBZ diesel end caps)
Pre-mix at 40:1 and you're on your way
Verify the jetting is good

Can you do a leak down test? That is, seal your engine up tight and pressurize it to about 6 psi. Then see how long it holds for before it loses pressure. This test will tell you if your seals or gaskets are leaking, and causing you to run lean. No need to grease an oil pump, since it's pumping lubricating oil. And there should be a gasket. Premix would require a block off plate (good ones run about $23 and has a blank to fill in the void of the missing pump gear) and you plug the fittings into the F/A's. Oil signal can be solved a couple of ways: keep the oil tank full and cap the hoses, tie the float up in the full position, OR install a 33 ohm resistor into the elec box where the oil sending wires are connected.
