got myself into a mess, never hard to start, and done all vacum lines but still idles up or stalls when i hit the brakes, i have no idea what carb is on it they made 4 different asians i beleive aswell as hitachis mines a asian with only 1 wire going to it, in ontario canada, you apparently cannot order a rebuild kit 

check your brake booster vacum.the hose has a valve
in it.
