I have a converted Poulan 42 with CH ignition. I don't have a big starter so I flip it by hand to start. The walbro carb has the choke and it takes approx 40 flips at full open throttle to get it to pop. Open the choke and it starts about two flips. The engine runs strong and idles/transitions well. The choke plate has a small hole in it. If I plug the hole with JB weld, do you think it will make it choke easier? I put a carb kit in it and no change. The carb is horizontal as the engine is inverted. All my other gas engines pop after about 6-8 flips choked. Suggest any other methods besides a starter? Also what is the difference between the RCJ6 and the RCJ7 spark plug and which is best for this engine? Thanks, Paul
