OK, my bad...You will find the carb has been modified to pass twice as much fuel..It should work, just not take as many turns on the needles as a carb made for gas...The plane was likely made to race at Madera in the early 90s...Or not..
FWIW, Brison was not in extistence in the early 90s....If you can see the con rod a copper color means a Sachs crank, a steel color means it has the A&M crank, maybe the reason for the rubber mounts,...Worst vibrator ever made for an airplane, one reason for the demise of A&M....
