      jets most certainly can add 2000 rpm if you’re off enough.  start with the simple stuff:  Too rich; fouled plug; dirt in the carb or fuel pump.

      Thanks, I’ll let you know how that goes.

      So today I checked my fuel filter, changed the spark plug, and made sure my reeds weren’t cracked.  That alone added a couple hundred revs so I’m around 13,500 for a quick second now.  I’d like to see what needle I’m running but I can’t seem to figure out how to take it out.  The other jets are pretty simple but this one is a little trickier.  Anyone know where to find any basic info?

      First off, top RPM for those engines when racing is in the low 14000, they fall off pretty quickly after that.

      Unscrew the top of the carb, pull the spring out of the slide, then unhook the throttle cable, you see a brass fitting, unscrew that and the needle will come out, do watch out for the small washer on top or underneath the clip, that’s for 1/2 needle clip adjustments.
