Welcome Lots of info on the cloans on karting sites, www.4cycle.com is a good one. I have never tried a Mikuni carb on a 120, should be a good choice tho. We use Tillitsons on the racing engines but for a trail sled, they tend to be rich at idle Might try to find a stock carb off a Briggs Animal.( not Briggs intec, which is the industrial version) The Animal carb is a copy to a degree of a Mikuni . Years ago I put one on my Honda XL70 pit bike and it has been flawless for years. |
