      Do not use starting fluid. I am rebuilding a K341 right now because someone used Bill Cosby in a can. Popped the top off of the piston above the wrist pin.

    I have a CV16S that’s backfiring through the carburetor. I see that all CV engines have hydraulic lifters, therefore no valve adjustment is necessary. Every time I try to start it with starting fluid it pops back through carb. It will run a few seconds until the start fluid burns up. Ideas?

      throw starter fluid away all you do is ruin the engine you wash down the cylinder walls with it if spray to heavy and in overall long run if you need starter fluid to start then you have another serious issue going on like a bad adjustment carburetor or poor fuel or lack of fuel in carburetor get a qualified person to look at fuel line filters and float adjustments

    I have a Kohler CV15S engine. I see that all CV engines have hydraulic lifters, therefore no valve adjustment is necessary; however, it has a constant clatter running that sounds like excessive valve lash. I can only assume, given hyd. lifter system, that noise must be either a collapsed lifter, or broken valve spring. I will look inside the valve cover to see what I can- It’s a service for a friend of mine with no knowledge.
    I’m a gear-head, so its no-brainer to me. The engine runs ok, except for the prominent noise. Please Advise any insight unreprised here. Thank You!
