UGH....My 1995 Husqvarna WXC610 is kicking my butt. Ran great for years but started having an occasional sputter. Finally the sputter became a permanent problem. It starts and idles fine, but once i give it throttle it starts to bog and go bam bam bam bam....which gets worse as i add throttle, and then it finally dies. Starts on choke when cold, dies on choke when warm. I have done everything i can think of including Total carb disassemble and clean (3×) Float height adjustment Replaced main jet...went crom 70 to 68 Inspected needle (looked good so didnt replace) and dropped it by moving clip up 1 notch to top groove from 2nd groove Replaced idle jet Replaced starting jet o ring Cleaned fuel filter Readjusted idle screw...doesnt have much effect until almost off...normally at 2 turns out Readjusted mixture screw...also not much effect..normally 2 turns out Flipped rubber gasket in choke plunger and adjusted choke cable play Adjusted all valves to spec Replaced timing chain....found out the hard way that the husky manual shows the wrong cam sprocket alignment...3rd times a charm Inspected cor intake boot leaks Inspected generator magnets New gas Inspected spark plug and wiring....good spark but plug looks rich Any gurus out there that can throw me some suggestions? Please please please
Here are 2,vids i posted on youtube so you can hear the problem while i vi e it some throttle....listen for the bam bam bam bam sound...... View: https://m.youtube.com/watch?v=zSVsa9FX6HQ https://m.youtube.com/watch?feature=youtu.be&v=tr4r8OFgbd0
Sadly those 95 electronics were the worst ones husky used, are you sure the whole magnet set hasn't rotated in the flywheel ? The coils were also suspect along with poor grounding from the cdi to the frame.
Thanks. Didnt know that the 95s were a noted electronic dog, but i did do a double and triple check on the magnets. That definitely could have been the culprit but i did rule it out. I had a starting problem 5 or 6 years ago and it was a loose magnet cage, which i epoxied back into place. Luckily at that time it was marked up and easy to get it remounted to its original position. Thanks again for the suggestion. If theres anything else u can think of Im all ears.....
Back then i also added a new ground for the ignition module, but i havent rechecked it, so thanks for that...i will take a look....i havent checked the coil at all though....i will check my manual to see if it offers a test with specific resistance readings....worst case scenario i also have a 92 husky 610 that i could try swapping parts with...
Personally, I would swap the entire ignition system out of your 92 if it's known to be good and see how it runs, cost is zero and not too difficult. It does sound like ignition to me. Tony.
