yes to keep up with the header and breather. It was running but and basically wouldn't start. Would back fire, but no attempt to roll over. Checked plug for fire and it was damp (and firing). Did drain carb bowel but didn't take it apart. Out of carb cleaner. Figure Monday try clean carb, then look at valves. Last look at fly wheel key. Had grandkids and parents all week and they were riding it a lot. Appreciate the in put.
