Had my first raceday with the 5 port in the truggy today. Iwould like some theories on why I had issues on my 5port.
I run th 5 port in my crt with the blade 4 shoe clutch. Mathed with a JP1 pipe this combo is great. I had some issues during the race. When I start her up the first couple of laps the performance is wicked. As I get to race temp after second tank it starts to lead bog badly. Tried richening the bottom end but nada. I couldnt be competitive as I did not get the consistancy needed to throughout the race.
When I got home I inspected everything. Leaking tank fuel lines nothing. Carb does not seem to be leaking on the spots seen on previous posts. This engine is just about run in now. The rubber seals of bottom end needle and top end needle is intact.
The engine would sound like its not getting fuel. Similar to when the tank runs empty. I did not have the same issues with the 7 port.
Any suggestion. Mark or Russ. I really like the performance and want to run this in my truggy.
