So now all Johnson lifters are bad, AFR heads are bad, nobs cams and cam motion cams are bad? And I'm still an idiot... That's what I get out of the last year of issues...
U Gil a year ago many guys happy with Bob and his parts, Johnson included... So now what? I get I posted and started much of this but at the same time if all the parts suck then how can they still be sold?
Not picking any sides just kills me once one issue is found we all jump on the wagon of they all suck of one did, yet no real answers to know for sure

And this is where my Salem comment s came from, they arent directed at your motors or problems, they are directed at this pitchfork and torches lets lynch them thing.... How do we expect anyone repping anything to stick their head in here when we have professional whack-a-mole players thirsty for blood?
This is a forum for boaters. Every company has a sales line, or a tech line you can call if you dont like what you read here.
Alot of guys bich and moan about others here, but yet offer nothing . No valuable posts, no personal experiences, not even an attempt to bring up a technical viewpoint for discussion, as this is an open floor. If your skin is too thin to get into online debates, maybe you need a safe space and a petting dog .
This thread wouldnt exist if this "whack a mole" , hadnt suggested tim yank his intakes and take a look at his cams. We'd still be hearing about how they are good to go another season

Obviously there are issues. Call it a witch hunt. Call it what you want. Is anyone making up the issues? I doubt it. Now to figure out why. Some of these things may have been thought to be a one off issue. That's the beauty of forums. A guy in Michigan and a guy in Florida realize they are having the same issue. May be a specific combination of components. May be a machining issue. Maybe a bad lot of a certain product. I think some people's products may be jumped on quickly by nobody here is saying any one of these products specifically sucks. Maybe it's an environment issue. Maybe an application.
The point of a forum which connects people all over the country and the world is to share information. Try to help one another. You're always gonna have the ford vs chevy. Cig vs fountain. Johnson vs morel. Be it online at the dock or in a bar. That's an inherent trait of competitors. In any sport. The question is will a true resolution ever be found. Is Randy or Kip gonna find it? Is Bob involved? I'm not an engine builder at all and trying to learn. I throw jabs here and there because it's fun. I'm truly curious what is going on though and yes every time a problem arises with one product others who have seen the same or experienced should and will chime in.
Again doesn't mean its junk but has to be looked at as a potential part of the overall issue.
