I have a question about setting the timing on a 2.1L

First off , which is the #1 cylinder?
Is it the one nearest the front on the passenger side of the van?

I've hooked up my timing light,
disconnected the temp sensor II,
but when I try to hold a 2200 rpm, the engine starts adjusting the rpms
by itself making it hard to set the timing.
Am I missing a step?

I notice on the Vanagon dealer service tape they have the additional
step of blocking the crankcase breather tube.
Is this necessary?

I can't seem to get the timing set because whenever I rev to 2200 rpm
the engine tries to adjust the rpms.

thanks,

Todd
