That thing is a beast! Did you measure the size of the valve? Just curious if its the same size as the one in my pauter motor?

not sure what size you need but the 22-26mm all looked the same .
I believe sudco.com still sells a vm22mm

Thanks mike.
Travis is putting this motor in his PJ1 frame for the ice this winter. Should be a screamer! Josh is reworking his 70 gas tank mold so we can get them to fit both PJ1 frames. :naughty:
