Perry pump with K&B red carb?
I am new to nitro outboards. I have a K&b 3.5cc outboard. I got the 3.5cc and it has the exhaust passage opend to one long hole instead 4 tiny small ones. The problem I have when I run the boat is I can run flat out for about 2 seconds and then the engine just peters out(no offense if you are reading this and your name is peter!!). I put a piece of balsa in the exhaust to restrict it a little and this helps, It will not peter out as fast but does loose top end power. I am also using 15%nitro by the way.
Now to the my topic. I have rc airplanes and have used the perry pumps on a engine and it worked great. I bought a red carb for this engine( tried the black carb and it does the same thing). Is the red carb and airbleed carb or can I use a pump with it. In the perry pumps instructions it says to use with a carb that has a low end and high end needles. If anyone could help with this problem it would be greatly app. I have check the entire fuel tank and hoses(no restrictions or blockage). I also am running a piggy back tank that aout a half inch lower than the carb. If you have any other advice to make it beat my buddys 7.5cc lapcat let me know
Thanks for the help in advance!!
