    Engine running on new fuel tank. Don't really like the centrifugal clutch, it sure is rattly sounding. Going to have to turn my idle up a bit!

    I have the extra leaf. Have considered installing it.
     engine engine in prop on plane running. Carbs aren't worth a damn. But engine runs. I don't think motor mount will be strong enough

    Fabricated exhaust .....Changed the four carb  setup to dual carbs.  Seems to idle much better. Got some brain storming to do to figure carb heat.....

    I have even been thinking of an aftermarket fuel injection.

     Hirth made a lot of those f30 engines. I think most were the two carb design which I think would have a whole lot less issues. I believe I'm going to try to modify and have one single carburetor. Matt at recreational power has a lot of parts for the f30. For individual carburetors I think is a really bad design for a 2 stroke

    Got the prop installed, Attempt to rebuild carbs....come to the conclusion Mikuni pump carbs suck.....My motor mount is probably not sufficient....anyway, it did run!

    Hirth F30 Carbs (Mikuni Super BN 38)
    Anyone out there have experience tuning Mikuni pump carbs? I have never worked on these type carbs. Having 4 of them seems to add a level of complexity that sucks....Figured i'd hit up the forum....
    Engine running super lean and fast throttles all completely closed. I am thinking that with the extremely low manifold pressure and having a high pop off pressure (55psi) was the problem.
    The pilot jet is a 77.5 and the high is a 80. The needle is a 1.5. This combo does mot line up with anything on Mikuni's charts.
    I'm changing the spring to make the pop off pressure to 22psi. Any thoughts?
