Good afternoon-
First and foremost, Marshall has been very helpful in trouble shooting. He has even offered to look the carb over, which I do plan on sending it in to him, but before I do that I want to give this one more shot in house.
General Information:
-2F engine with Headers
-No vacuum leak
-Timing is correct
-New OEM fuel filter, and Fram inline filter added out of gas tank
-Fuel pump and lines are new
-Fuel tank is clean and properly vented
Two issues:
1. Hot Starts
-When warm, regardless of drive time, it is a bear to re start. Foot to the floor, no pump, and it will turn over for 2-6 seconds before firing up. The longer it goes the harder it starts. Some extremes it will foul a plug and obviously run like terrible. This problem has always been here.
-Pull the air cleaner off and you can watch fuel drip into the secondary. See video/photos.
-I pulled the secondary jet to clean, and you see fuel is in the ventricle, same level as the bowl.... Hmmm this can't be correct.
-I have disconnected the fuel line and there is zero built up pressure. It still drips with the fuel like off.
2. Acceleration Issues
-When driving up any type of incline, under load, it will buck and back fire. Ease off the accelerator and it smooths out. Recently it is near impossible to drive up big hills at any speed that won't get you looked at. This problem is new, but has quickly gotten worse.
-I have cleaned the carb out, no improvement.
-I believe this to be fuel starvation. @Trollhole agrees.
I'm interested to hear your opinions. If this carb does not work out I have two options; City Racer Japan non USA carb, or Mosley Motors sniper kit.
