Black Plugs / what now ?

The VRO is not adjusteable on these engines. I reccomend the PENNSOIL synthetic blend for any of the old school carbed 2 strokes. Its priced right, available in many places, and burns relatively clean. As for how much oil it is injecting, have you checked how much oil to how much fuel you are using? If the VRO is working, it shouldn't smoke much at all at idle. Sounds like you have an air leak in the fuel line going to the engine from your description of the smoking. Remember that ifyou are running it hard, it should use roughly one gallon of oil to 50 gallons of fuel. And if you are running it at idle to slow trolling it should be closer to one gallon of oil to 90-100 gallons of gas.

Thanks for the info Thefermanator . I did a complete check of the gas lines yesterday .. and MAY have found a slight leak. To be safe I replaced that area of line. I was also told I could switch to a L78V { chanpion } spark plug . Its the kind that just has a dot in the middle no gap setting on this type. Anyone ever use this type plug ?

Stay with the QL77JC4 plugs, TRUST ME. The QL78V plugs use a longer reach electrode for prolonged high RPM useage and will foul even easier at idle.

Hey Wildtalk, F a Champion plug. ASE certified tech(come on guys you know you should spout it)with minimal ex with O/B. F a champion! Everytime I put one in, not so much. Still have to kneel to the pros! I may know stuff elsewhere, but this is where to find the right info.

Are you trying to say CHAMPIONS are crap or something? If so you obviuously have never dealt with OMC outboards as they are the only plug that will run in one. Yes, I used to be ASE certified but let em expire as working for myself I have no need for them with my clientel. I have experience working on just about everything out there from cars to boats and classic cars. And most of the ASE guys I worked with I wouldn't trust to fix a go-cart.

Sorry just a little rant there. Ferm, I see why you got away from the car biz. I too work with jackknobs that can't even replace a spark plug, let alone know anything about engine performance.
So no regular NGKs either?

In a EVINRUDE or JOHNSON with carbs run only the CHAMPION plugs. The QL77JC4 work for almost all of there engines, and are the best all round plug. NGK's are known to make an OMC run like CRAP! Even some of the older MERCS run better on the CHAMPIONS than NGK's. But on the other hand, I've put CHAMPIONS in YAMAHAS and SUZUKIS and had them give off horrible radio interference.
