Hi there all,

I've been observing eversince I'd been flying with our senior old flying friend as he has 2 airplanes one is 25 or 30 size other one is 40 size. One is low winger and has .30 O.S. Engine and other one is high winger with O.S. 46 engine in it. The plane with .46 size engine has muffler nipple leaky, it leaks the fuel all the time durning flying. Sometimes it does give dead sticks but it really flies despite of that fault.

Little low winger plane has carb needle leaky, high speed needle but it does fly good with good rpms and few times it gave us dead stick. Both planes I fly and they fly well, my question is, do these factors make any difference in engine's performance or not and as I didnt experience much problem with those engines, could it be a coincidence they kept running or should this problem be fixed?

Please suggest and advise from your past experiences if you had gone thru

Thanks

Mody
