1978 hobbit jetting (dellorto 21mm carb, 60cc, proma circuit)

Dillon Nelson /

Hi,

I have a 1978 honda hobbit pa50. I recently purchased a 60cc stocko shocko big bore kit, proma circuit exhaust, and a 21mm dellorto carb. I have had some trouble tuning the carb correctly, and it is a pain to access it. Any suggestions on jetting?

Thank you,

Dillon

Same Here 60cc kit with 21mm Dellorto proma exhaust. It came stock with a 90 main jet but cant get it ti turn over.

U need a smaller idle jet like a 42 or a 45. Wayyyy to much fuel with the stock 50 that comes with the phbg dunno about your main jet. I hover around 94 -102

It will always be a pain to access it. Cut out your air box per the Cheetahchrome wiki article.

Ya a low RPM pipe matched to a big high flowing 21mm Id carb that will spin 60cc to 13K rpm all day.
