I have looked at all of the information on carb modifications and it is not clear to me what exactly is to be done. From what I have heard from people at runryder, it seems that the modification is on the spray bar. But from a website it seems that mod is on the carb barrel "carb body". I do not know what exactly is to be done. My spray bar looks like a diamond with two little circle indentations at one end, but I do not know what exactly to compare from safecracker's picture.

There's two mode to this engine - one to the barrel and one to the carb body. The one to the carb body seems to be the best - if you screw it up you can always close the hole up again.

Carb mod..
This engine is not for everyone as it takes a good amount of time and finess to achieve happiness with it.If you have the carb that has the slit with the hole at the end, then you have the new version carb.The mod is use to introduce extra air at a given time.The modified spray bar deals with the problem directly.I had to use a run up stand to achieve what I wanted out of it.You may want to find an alternative to this engine, especially if you don't have the patience.I received a 46 a while back from a buddy and it had the carb drilled.I couldn't get that thing to run for nothing.It would run but die out at mid so I plugged the hole up and have had nothing but luck with it since.Hope you have luck with it...
