Avid Model A Rebuild

If you drop one blade, (from 3 to 2) you probably don't have enough pitch adjustment without changing the gear ratio.  Ed,  an IVO uses the same hub, 2 or 3 blade.  Spacers are used to make up the difference between 2 and 3 blades width.  JImChuk

What I like about the Ivo prop is if you have a 3 blade and you ding one you can change it to 2 blade really easy

Don't you have to have a 2-blade hub to do that?  You could do the same with Warp Drive and 2 hubs.  EDMO

Ivo uses the same hub i believe.There are spacers needed. Thrust issues may be a issue with the ultralight model, I think the medium model would do ok repitching......

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!

I wouldn't go that far ha.

I think its the engine design we had one of those engines local on a kitfox. It flew twice and both times the # 1 piston melted. Didn't want to say that earlier because I was really hoping yours would be a turn key machine. Those engines have gotta be out there flying. Some one must have figured it out by now.

 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

 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

I have even been thinking of an aftermarket fuel injection.

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.....

Really, really nice build sir. Kudos as well to most excellent photos and updates of your progress. 

May I suggest (if you've not considered it already), replacing the inadequate 1 leaf tail spring and updating to a 2 or 3 leaf tail spring.  www.wausauspring.com offers a nice 2 leaf and supplied to the early kits back in the day I believe.

I have the extra leaf. Have considered installing it.
