Re: Gravley carburetor

Not many 430s were built with the G30 12 hp single cylinder Onan engine, so your 430 is special in a way. For that reason we can't start to narrow the carb. down as being either a Kohler, or Walbro carb. as we could with a Kohler engine, unless someone here may happen to know what carb. it is.

Try "googling" your engine, adding "carburetor" to your search ("Onan G30 carburetor") and see what comes up. You may also want to post a few pics of your carb. here.

Re: Gravley carburetor

If he posts a picture of the remaining linkage and the intake manifold guys familiar with it might see something...the other thing to do is get all the numbers you can of the engine and call Jacks, or Searsdirect, or repairclinic

Re: Gravley carburetor

I don't know this engine, but it looks like it has transistorized ignition. If so, the module (is that it hanging in the pic?) needs to be installed in order to generate spark. There should be a magnet in the flywheel that generates an ignition pulse in the module (spark) as it passes the module's contact point. The .008 gap listed on your engine's data plate would be the gap between the module contact point, and the flywheel.

Re: Gravley carburetor

Well if you have no spark your up the creek with a broken paddle. Haven't made a bolt on module to work since the 70's is what I was told.

Basically you have to build a spark system. rw3dog on youtube has a good series on what he did to make them run. I have one of the few working spark boxes this side of the US on mine. So im not much help there
