Devon Posted July 27, 2011 Report Share Posted July 27, 2011 I recently drilled my carb to put a vacuum outlet on it but its not working, the internal diameter of the feed tap is just over 1mm so could this be too small? should i drill it out to be a bit bigger?

Devon Posted July 27, 2011 Author Report Share Posted July 27, 2011 I drilled it on the side of the carb, on the reed valve side, instead of the air filter side. Im going to try and bypass this damm tap. Link to comment Share on other sites More sharing options...
lorenzo Posted July 30, 2011 Report Share Posted July 30, 2011 The bungs in the vacuum holes on the srad are m5 I think, maybe m4. Don't know if your 1mm hole is too small, but it's certainly not too big! Link to comment Share on other sites More sharing options...
