40mm is way way too large for these.

40mm is perfect for the bolt pattern.

He said 40mm bore, not bolt pattern

Ok so I cut the intake back to one 45° corner and installed a new spark plug but it's still not starting. I'm using a 40mm bore carb. What else could it be? Could it just be old gas?

It is no wonder then that it won't start.

Ok so as for the 60mph claim it was done with a gps speedometer app on my phone. As for the carb well I wonder if I just don't have bad gas.

My next door neighbor has a speed gun fo harrasing the neighborhood speeders (we are 25mph). I am going to try and compare my gps based apps with the gun.

I am just wondering if that app was set to kph. 60kph = 37mph.
