Fourwheeler: 2002 foreman 450 S
Problem: starts when choked, runs fine on choke for about 10seconds, then spits and sputters until dead. Sometimes runs for roughly one minuite but it spits and sputters down to low rpm followed by returning to high idle (choked) every 10seconds or so.
Things I have repaired/replaced that I know were bad: timing chain tensioner, timing chain, and the tensioner arm/.
Things I have repaired/replaced that I thought were bad: brand new carburetor off ebay, rectifier/voltage regulator (used in "good condition"), new spark plug, ignition coil (used in "good condition").
When I replaced timing chain, tensioner, and such I just put the piston TDC (thru hole with both dots aligned on cam/sprocket with mark on engine case. I turned motor over by pull start rope and verified dot/case mark alignment and tdc thru inspection hole, also rockers were slacked.
I also put air line on spark plug hole to verify no bent valves, held pressure fine with no leaks thru intake or exhaust side.
I verified there was no restrictions in the muffler by removing all baffles and the whole end cap arrestor.
This is the carb I bought http://m.ebay.com/itm/381796235070?_mwBanner=1
After all of the above the problem remains the same.
I am at a loss. Any help would be greatly appreciated as I need this thing back running for the ranch.
If theres a honda guru on here that would like to take the time out of their day to help me out over the phone I would greatly appreciate it.
I am mechanically inclined and with a little more honda experience help maybe I could knock this out!
Thanks in advance,
