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?
