Been tinkering with a Honda Fourtrax 300 that my FIL has. I got it running fairly good after I removed the carb and cleaned it. When it is cold it needs to be choked for a good while to keep it running and it will start to run away with the choke on. When it is kinda warm it will idle nice and slow but will miss once every 5 or 6 fires. It misses like you were to shut the key of. When I was working on the carb I couldn't get the motor to fire and found out there was no spark. After turning over the motor some more I got an erratic spark and then a consistent one. When the motor is good and warm the low idle is not low any more. The motor begins to climb in rpms to the point when you put it in gear the thing jumps. Also when running the four wheeler down the road it will run perfectly at half throttle. At slightly above idle it will start to buck a little like you were turning the key off and immediately turning it back on. At full throttle it has a knocking noise but not a hard knock kinda half way between a knock and a hiss.
What would be causing the increase in idle as the motor got hotter?
Would a bad ignition modual explain the complete miss at idle and the lunging at lowerer rpms on the road?

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
