Pre-mix or VRO?

[ddcarter3]

I have a '87 Johnson 70 HP VRO. I am rebuilding it and wondering whether or not to remove the VRO and just premix. If I remove the VRO, how do I do it? What extra parts are there? If I keep the VRO, is there an alarm to tell me if the injectors are not working?

Check out the articles on whether or not to disable VRO and how to do it, DD. They are in the Engine FAQs section.

Good luck.

Re: Pre-mix or VRO?

I asked the same question about a month ago.
my solution was: both
considering your VRO is an early VRO it mixes alot leaner oil mixture than the later VRO's do.
mine is about the same vintage VRO.
i am sure it is fine to idle at 100/1 mixture but it won't hurt to have a bit more oil.
so i mix my gas at 100/1 and run it with the operational VRO.
And Yes it should have a warning system.
I plan on running my VRO this way until the pump dies and then i will replace it with a regular fuel pump and 50/1 premix.
it does not smoke any more now than if i premixed and i have the assurance that it will never run completely dry of oil.
