I have a 25hp OHV V-twin model 445777 that is running rough, and seems to be running on the left cylinder only. Exhaust temp with laser theromometer is out of range at the exhaust pipe on the left side, and around 150-190 on the right.
I've checked and replaced both plugs, and adjusted the valves (.005 In, .008 Ex) These settings are .001 higher than specs, but I was given wrong info from a local shop, should be .004/.007 respectively. This surely isn't bad enough to keep it from running smooth, is it?
I also checked the spark, getting a good blue spark up to about 1" from the head when running @ half throttle.
It's backfiring thru the carb, but not consistantly. At idle, the miss is really noticable, as I speed the engine up, the backfiring starts.
I don't use it as a mower, just a yard dog to move trailers and stuff around the yard (got it for free, so I'm not out much in that area, but I have put new tires and some other parts to make it more reliable)
Any suggestions?
