Missiong on one cylinder

[bustamove]

This sled seems to be getting worse and worse ever since I put it into reverse.
When trying to idle it runs on one cylinder you can tell cuz pto hot mag cold. Mag side plug is wet, looks more oily then gas. Both plugs were new. Put new filter, set tps to 0.94, and baseline was good, what eles should I be check, put new gas was put it in

did you pull the plugs and crank the engine to see if you have spark on both sides? Also do a compression check if you can.

are you getting any engine codes? I've even seen new plugs that are bad so like zman said check your spark, and maybe change the one plug that's not firing.

Yes spark on both cylinders, compression should be good just rebuilt entire engine less than 20km ago. Would reeds cause this problem?

Also switch the plugs between cylinders same issuse

check all your wiring and ground connections.

Compression should be good and is good are two completely difference things. Hopefully this is not the problem but lots of new engines fail.
