70cc eurokit jetting weirdness.

So I'm running an old 70cc eurokit with a tecno boss and a dellorto 14/12 on my swinger2. I know the carb is super small for 70cc's, I'll change it to a 16 or better at a later date. Anyway, Right now I'm running a #63 jet and its way too rich to even get a plug chop. It'll just drive around at like 10mph choking to death on the extra fuel. So whats the deal? I know that the carb isn't going to allow much air flow but that just seems odd that a 63 would be too rich. On the plus side there are no air leaks.

The dellorto sha has no needle. I'm just going to take it down and do it up with a better carb and intake. Not worth the effort buying the jets to make it run with the tiny carb, expecially little jets.

saabi you have to do the nascar restrictor plate trick and let the carby run super rich and put a controlled leak in the intake, the new cylinder is drawing way too much vacuum for the tiny little sha.
