Engine Lubrication

[j11eck]

I am extremely new to this world of the Fl250. I recently acquired one that was in several pieces and I am trying to understand how it works as I put it back together so that I do not make any serious mistakes.

My odyssey is a 1983 Fl250, when I received it, the carb, fuel cell, fuel pump and the rear cage were all removed. I believe I have figured out the proper plumping of the fuel tank and carb, I have repaired the leaks in the tank, and I am about to reassembly the fl250.  I have test fired the engine (immediately killing it once it starts) by simply gravity feed fuel flow. I was impressed that it only required 2 pulls to start with the choke in the on position.

Being new to a 2-cycle engine, my question is this, if the port on the engine only operates the diaphragm pump, how is the engine lubricated on the bottom end, or am I a complete idiot and no lubrication required due to the use of ball bearings? Furthermore, is there anything else that commonly overlooked in this process by a noobie?

I welcome any advice you may have to offer me.

The lower end is lubed bythe 2 stroke oil that you put in the fuel...When the piston goes up for the compression stroke,the vaccum created in the lower end pulls fuel into it,then as the piston goes back down,the fuel is forced throught the ports to the top of the piston and the process repeats...That's why you should only use a high quality 2 stroke oil...There is a lot depending on it...

Can someone tell me about the oil specifications? In 2 cycle oils I have seen a universal oil and TC-W in the store, is there a difference?

tcw is for outboard marine engines....The universal crap is just that...Don't use it....Use Amsoil or some other quality synthetic oil....Bel-Ray makes a good oil as well....

Amen Hoodlum.....If you can't find Bel-Ray or Amsoil around where you are let me know.  I am a Bel-ray dealer.
