Little help with my first e50 build?

Hey guys;

I just rebuilt my first one - rito crank, 70cc airsal, dmp carbon (estoril), treats CDI. Case matched. 15mm bing

I sealed it up!

First of all, I checked the compression, ~180.

CDI getting spark, but oddly enough it looked smaller than before - perhaps because I'm using a BH7S plug for the first time?

Kicked it over, nothing; squirted some premix in the head, started after a few tries; revved that little gas in there and it was scary powerful.

My question is what should I try next? I believe I've got a high - 70's jet in the bing, it IS definetely getting fuel flow, I should probably put in something higher like an 88 for breaking in..

As far as getting it to start up well, seems like I need to give the carb and possibly the CDI timing some attention?

Or is this just airleaks?

What strategies to you men and women recommend?

How did you setup the Treats Cdi?

I tried the fully retarded position; one of the more recent posts in the CDI thread recommended that; but now I'm seeing posts saying fully advanced. Pickup is on the right, just how it came.

I think I need to learn how to use timing light etc.

When i revved it with gas in it, seemed quite nice though
