Hey all,

Got my 914 running to the point after sitting for 15 years where I can actually drive around the block. Trying to synchronize the webers and noticed that when I put the unisync over cylinder #1, the engine's rpms rise to over 2000. Noticed the same on cylinder #6 but not as pronounced. Opening up the unisync all the way still causes the reduced air to the intake to cause the rpms to rise.

Is this normal?

I have the idle and air mixture screws at the default settings and would try adjusting but it developed an oil leak under the oil filter somewhere so have to fix that first before tuning more. This car has been 2 steps forward, 1 step back all summer. Almost there though.

Thanks for the insights.

Peter

The old style Unisyns do restrict the air intake ... the newer 'snails' are much better.

If your RPMs increase when you restrict the air, it's possible that your idle mixtures are adjusted too rich.
