Nothing in the filter. Im not saying the carbs are necessarily wrong in general, but it seems they are in need of a possible jet change. Cant be right using all that fuel for 450 miles, backfiring when decelerating, having to change the oil 2 times in 450 miles due to gas contamination. I read the carbs are around 130 cfm. 2 of them would get me to where i kinda need to be with the 235.
Granted I was told by tom no adjustments are required but it just seems way too rich. Who is to say now i did not cause damage due to piston and cylinder wash on my new rebuilt engine due to this.
