Motor starts,idles, and runs good when started cold. Run up the lake and fish for 20 minutes or so and restarts fine. Give it throttle and it only goes to around 2300rpm and missed. It stays this way and wants to take off full speed every now and then. Let it sit for awhile while fishing, and restart later and it runs perfectly and it runs good the rest of the day. Next morning, the same thing. New plugs(HGK) and same thing. Last time it did it, pulled plug wire one at a time and the three on the right side were not firing. Motor made no difference in sound when pulling plugs on R side. Pulling plugs on L side did cause mortor to bog. Same thing when I blocked each carb. It is diffinetly not hitting on the 3 R cyl. Power Pak???? If so, can I change it myself without special tools are set up? Any checks to perform to verify problem? Any help appreciated. This did this 5 days in a row during a recent fishing trip.
