Carrier 58gc100-2a furnace

I have a Carrier 58gc100-2a furnace and Burner keeps cycling on and off how can I troubleshoot this? I have lived in the house for two years and have not had the furnace cleaned. I can see debree in one of the chambers. Could this be causing it to cycle on and off? The burner fires for about 30 sec then shuts off for a short period then fires again.

Thank you so much for your assistance. I do not see anything that fits that description. The closest thing is a rod or tube that is 1 to 2 inches long that leads up to the pilot light.

Ok well the flame sensor is there with the pilot. Need to remove it and clean it. Be easy to pop it out.

Is this furnace closer to a 1973 or closer to a 1983? The 3rd and 4th digit may indicate year. Older models used to have a letter and number indicate year. A thru M indicated 1970's and N thru Z was 80's. I recommend having your furnace professionally inspected.

I think I just shot myself in the foot. Could not take that piece off so I cleaned it with a tooth brush and vacuumed the top of the burner tubes now the furnace will not fire at all. Any suggestions? I live in Richmond Va we just got 12 inches of snow I will not get anyone out here to help probably for a couple of days.
