Seems to me 35 to 1 is going to smoke like crazy. Dosn't that Variable Ratio Oiler deliver 50 to 1 at Wide Open Throttle, and LESS oil at lower RPM? Good concept though, especially since fuel consumption is highest at WOT and most operators like to run at lower speeds. Personally I have bypassed VRO oiler and run at 50:1 all the time because the consequences of under-oiling are so catastrophic.
mine is not working and was wondering can I by pass the injector pump. And then just do a 50 to 1 ratio mixture in the gas tank? If so what do I have to do to bypass the oil injector?
The symptoms you described are exactly what I was experiencing with my '88 50hp Evin with VRO. I got carb rebuild kits from Crowley.
Rebuilt the 2 carbs and resecured all the hose connections, about 12 places.. (I used metallic worm gear type where possible and I did use some new zip ties on the smaller dia hoses...really tightened them. I couldnt find the squeeze ratchet type you described. Whole job about 10 hrs, and you were right!!!! Engine runs like a champ! what a difference!
when I press on the button it stops the motor noise. I changed one relay a month ago, thought it was the same problem, so I changed the second relay but it did not help.. I'm a chick and had to get in the water to try and raise the motor...luckily a nice man jumped in the water with me at the ramp and we were able to unscrew pressure screw and at least get me out of the water.

Use two gas tanks one with 50:1 for trolling , and another with 35 or 40:1 for speed run and a selector valve ,, that's it ,
