[QUOTE="Chris Launders, post: 160375, member: 2010"] I'm not that technical but it seems to me that as you have increased the engine size by 66% (833 is 500 +333 or 66%) you need a carb with an 66% bigger cross sectional area to keep the same gas speeds then you will also need jets 66% bigger to supply the fuel (assuming the jet size is based on flow and not diameter, if it is diameter then it's a bit more maths as you want a 66% increase in CSA) Or is that me being too simplistic. Chris. [/QUOTE]
