Last Saturday I ran my Hartman with dual Mc101s at the Santa Maria track. The 101s have 34 mm Mikuni pumper carbs on them (one carb per engine). The engines/carbs ran really great - after I finally got them started - it took forever to get the carb pumps pumping. I had to go to a lot of trouble fill...

When I dressed the new reeds, I only used 400 grit emery paper. Makes sense that 800 or 1000 grit would be better.

Are steel reeds ever used on these engines?

The reeds in my Mc101 are getting badly chipped for some reason. I understand this is not unusual, but the last set of reeds lasted less than an hour. The second photo below is an old reed that lasted a number of hours - seemed reasonable to me. This reed was .023" thick. The first and last photos s...
