B50 Mikuni
« on: November 14, 2012, 02:45:19 pm »
My Metisse witch is powered by a modified B 50 motor is currently running on methanol via an Amal concentric carb .

I want to probably fit a Mikuni ( with choke ) and run it on petrol or Av gas .

Does anyone have any experience of fitting a Mikuni and jetting specs to start with .

Any other suggestions re carbs are welcome , the reason for not running methanol are easier maintenence and i dont have a convienient supplier .

Thanks Bill

Bill, as per your mxtrax post, have a look at the forum on www.b50.org
I tend to avaiod avgas as it is a slower burning fuel. The best I have found to date is to use 20-25% 114 octane leaded race fuel mixed with super un-leaded (97 - 100 octane) No pinking, and it all seems to stay clean.
