Stock 'Chinese' carbs have a very poor surface/shape on the intake side which is restictive to the free flow of air IMO... (If any of you guys got one, You KNOW what I mean here...) This thread is to help guys squeeze the last little bit they can out of their 'stock' carb on their 'chinese' pocketbike without spending a pile of money in the process...
This mod works BTW... :yes:
Many of you guys that read my rantings know how cheap I am... :innocent:
I could not bring myself to spend $10.00 (or more) for the cone shaped grinding bit at the hardware store (and I didn't like the angle on it either FWIW...).
I made this tool using a piece of scrap, 80grit sandpaper, a 'hotmelt' glue gun I bought for a buck at the 'dollar store', and an old stone that I had wore out sharpening mower blades...
I got a buck and 10 min. of my time invested in this tool. Most of the parts were trash... We ARE very 'big' on recycling around my house for sure! :sherlock:
This tool is BETTER than the bits at HomeRepo because I can control the dimensions and angle of the cone and get any sort of bevel I want with it. The angle on this cone can easily be adjusted by simply loosening the hot melt glue with a hairdryer and then resetting the paper. Any old broken drillbit will work for the shaft so long as you use enough hotmelt glue to hold it all securely... (You will need an electric drill as well) :headbang:
The pics below are of the tool and the carb that I ported with it. :cool:
Important: If you hog the carb opening out to the point that you have NO flat surface for the choke valve to seal up against, You WILL have a 'non-working' choke on your carb. You have been properly warned here friends... :innocent:
My son likes it for sure... :yes:
