just installed my modded end cap (that is loud!!) and it when i give it full throttle, it just bogs, doesn't want to take it. i think it means rich on the main? it only bogs from about 3/4 throttle up. also, when i release the throttle, it almost wants to backfire but it doesn't. just a little lean in the pilot? turn air/fuel mixture screw out to richen or possibally a larger pilot? thx..

 

did you jet up at all i think 170 to 175 is the range.

 

175 main, 40 pilot, float level is pefect.
