Motion Pro carb sync tool

Just saying that mine works fine, that's all. I use my Sync Tool twice a year at least, after every-other valve clearance check, whether I need to replace shims or not.

The "junk":ohmy: works far-better than nothing, for me.

I made my own out of 4 gatorade bottles and filled with 2cycle oil. Gives me piece of mind mostly I think since I can get them darn close by ear. Old school and works great for the snow sleds too. To each his own as long as your happy with the results for the $$ you cant go wrong. John.
