Decided to clean the carbs on my f2. Rigged up the tank to hang above the bike to get to the carbs for carb spray. All carbs would bog engine except one carb. So, I gave it more spray, no effect, more and more. Then it died and wont start now. Need advice.

 

float levels?

 

Not sure what you are saying

 

You might of flooded it. Or even foul your plugs with all that spraying. If one cylinder didn't bog while spraying, it might not even been getting spark.

 

Started right up today. I'm thinking flooded.

 

How high do you have the fuel tank hanging above the carbs? I remember someone saying that you have to keep it around the same level as the normal tank, or else the gravity pushes gas past the float valves and floods the engine.

 

I've had fuel bottles over 3 feet above the tank with no problems. If your floats give out from that you have bad floats or float needles/needle seats. Anyways, that's less than 1psi of pressure, do carbs with fuel pumps have significantly different float needles? Something makes me think they're about the same.

 

Tank was same level. All is good with the carbs, kinda. Now my countershaft seal is leaking. Do I need to split my case to change it out?
