Hi, I got a Johnson vro 90 hp on my boat, it boggs hard off the start and won't go to full power until trimmed out, or what I think is full power. I just bought this boat and this is the last bug to iron out. The model number of the engine is CJ90TLCDC, I have pulled plugs and all seem to be running lean exept on on the bottom right, drivers side, that plug is always wet with gas. My question is I could not find any adjusting scews on the carb, are there any? Do these carbs need rebuilding or is there a bigger issue? Are there any reeds in these engines? When the plastic cover is off and engine is idling, I have gas mist coming out of the left bottom carb port, which is why I'm asking about reeds. I have a service manuel on order but has not showed up yet. Also, what plugs do you recommend for this motor, I'm not sure if I have the right ones in it but I have NGK BR7HS in it now. Any help would be greatly appreciated!
