honda 350 4x4 starting problems only sometimes

[scotty2hotty01]

i have a older honda 350 cc quad that seems to start and other days will not.spark seems to be gone and there when it does run.I checked newer coil odd a older yet Honda but no help and idea I going to find the serial number as forget the year but believe around 1995 to 1997 year besides that great quad but cant run it so great this way  and need it for chores around the acreage. Any help would be great. Ive check all fuses as well as the fusable ling which was fine until I screwed with it now need to buy another as have it wired not so safe.I handy but now have copd which takes away the brain power some.Any help would sure be appreciated

Could be fuel or spark related. Have you cleaned the carb or has anyone messed with it?

[Conner ozborn]

Have you cleaned the carb as Ajmboy said? Or tried a new sparkplug?

so turned out to be the CDI.Ibet if you know someone with same quad switch it and bet it starts easy each and every time.Mine took a few years until no more spark.Perhaps keep a spare plug around as bet  you see no spark.I only wish I knew this when mine started giving me issues.I also tried the oven trick but never helped one bit.Also must be off same qurd motor size so no testing with other either.Sorry if this doesn't make a lot of sense but I almost falling asleep while writing this post bro.Hope it helps but my cdi lasted for many years but the replacement was like 220.00 Canadian.The dealer even had ne in stock which was so nice for me as the recyclers had none so had to buy new which when it worked it was so nice again.ÙBest quad or should I say tank wish they still made them so tough.Good day & good luck.

That’s good news brother.   
It hurts having to pay that much money for a part but you can’t go wrong with an oem cdi.  
It’s a solid state component and can’t be tested unfortunately.  Anyway I’m glad it worked out for you ride safe.
