When I start my Kar after it has been sitting for a few days I'm getting a vibration which I can feel in the clutch pedal and I can hear when I open the hood. After the car is in a fast idle the vibration goes away and I do not see or feel any difference in the performance of the car when I'm driving.
Anyone have any thoughts... Thanks in Advance.
Could be a number of things, such as: front/rear engine mounts, driveshaft imbalance, engine imbalance, etc...
does it go away when the motor is warm?

goes away completely after the engine is warm
thats what I thought.
do you use the choke when starting ?
Have you checked the spark plugs?
did this start all at once or was it gradual in being obvious?

Z -- I use the choke when I start it up and it was a little more subtle at first and now you can't miss it.
this is one of those things that will drive you crazy tracking down. I'm split 50/50 on carb or ignition. Check the easily checked items first. Fouled plugs comes to mind as number #1. If they are fouled, why are they fouled? Do you get to really get the motor good & hot when you drive? How long are you driving it ? What are your driving habits ? Can you really wring it out a few times each outing ?
Ignition: bad plug wire, fires intermittently. Could you have a crack in the distributor or moisture under the cap, clears up when motor is warm.
good luck, and keep us posted.
