Engine slow down

[Doehring]

Hi all,

I rebuilt my carbs 'cause I had the well known problem that there was a "rev limiter" at 5000 rpm. This problem was discussed in another thread up to 2 weeks ago.

The engine now runs fine and the colour of the spark plugs is ideal, but when I have to stop for instance at a red light the engine starts to die (revs go down to 100 rpm) for a short time, than idle goes up to normal (700 rpm) again. I didn't have that effect before the carbs tuning. Any idea what is wrong and what I have to do?

Thanks

Rolf

This is a tuff one. When the engine drops the RPM is it running roughly and then it smooths out to a 700 RPM Idle. is that right? What happens if you depress the throttle quickly and run the RPMs up ? What I am thinking is that it may be loading up like maby a float level is set too high. Just a thought.

Sort of the opposite of my carbs, come to a stop and the revs go high (1100). I thought that was because of high float level?

Thanks for your input. Compared to ZTherapy's proposal the float level was okay. I changed to an electric fuel pump and the problem is gone, don't know why.
