I am a new member here. I recently picked up a Fourtrax 300, the PO was unsure of the year. I could not find any numbers on the bike; they are faded. Whomever had this before me had used it well. It was having trouble running above idle, so I cleaned out the carburetor. That seemed to help it for a bit, but then it had a super weak spark, so I figured out the CDI is bad. I am not sure which one to order; is there any difference in these? The ones on ebay have them listed for very specific years, and since I’m not sure which year my bike is, I’m not sure which one to order.

The numbers on the CDI are:

Philips Technologies
HM5 3294

Thanks for any help.
