Hi Ed,

Just a curiuous question, engine flamed out several time, hence took it apart. The big end of crank and conrod have worn away. Not much compression as the piston have worn away ( could push the piston all the way to the top !!! ( measured the piston and sleeve and compared it to a new one !!). Replaced conrod and piston from another unsed NSR, but using the original BRB sleeve....very tight fit, hence have to run in engine again !!!..........finally the question is that i am 100% sure the piston have worn away, so what is the original diameter for the sleeve as i want to compared how much the sleeve have worn.........by the way, this BRB set have been through more than 6 gallons !!!!

Thanks

philip

p.s acquired one of Green engine...placed the sleeve into that !!!
