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.
ok thanks.I seen the carb your talking about this morning on a gokart site.I will try and get one.I was wondering if the pz19 mikuni from the 110cc atv engines would work?.by the way the 6.5 clones are on sale now at princess auto for 89$ for those of you that are from canada.im also looking for any engine upgrades....I bought 2 engines....I will build up the 2nd one over the winter thank again, cant wait to see this sled run!!
