Can valves cause difficulty cold starting?
My bike is a 24 year old trail bike. It was fine but lately it’s been harder and harder to start while cold, but runs fine and starts fine once warmer up. Could this be because of valves? Or would valves only affect hot starting? I have put about 35 hours on the bike, and I’m not sure how long it’s been since previous owner did valves before I purchased. It was okay up until my 2 most recent trips
