    Yanked the head off and found no cracks. Will replace the gaskets and give it another try.

    Going to pull the cylinder today to verify it. But with the luck I've been having  with this project?  Buying a used cylinder would be risky and it could be the head cracked which might be repaired. We'll see.

    Just checked the price for a new cylinder, almost $1000. Beginning to rethink the whole process. Maybe get back to trout fishing!

    So much for the trying adventure. Its become a love/hate issue. Found a small oil drop underneath one of the cylinders after running it and most likely going to be a cracked head. Could have been that way from the factory or somebody with no torque wrench. Now to pull the cylinder and find out.  Doesn't seem like I'll ever get to fly this thing!

    Just bend a little at a time. I know its a pain, but going thru the gas cap with a piece of safety wire you can raise the arm to check your adjustments. It will register (using safety wire) without gas.

    Look up Airscrew Performance in Glendale, Az. Steve Beatty, he has the personality of a cold rock but he has been in the game 34 years. If he can't or won't then your left with Rotax Rick. People either love him or hate him.

    You can pull it out and adjust the arm on the float. Aircraft Spruce also sells them. It is a bendable arm or can be shortened, depending on what you need.

    There is a third party liability insurance available through the USUA that is pretty reasonable. For me on the Kitfox, it was around 350-400 a year for a million dollar policy. Of course one has to belong to the USUA to get it, since it is underwritten thru them. But I am not sure the difference between a third party insurance and an Avemco policy.

    Thanks! It has been a trying adventure. Hopefully it will be worth it. Still a little more tinkering to do but it makes noise.

    Book calls for 45 idle jet. I figured they were the same jet but this is my first 64 carbs. Thanks!

    I think max is 1400 but I checked the main jet and it is 125 which is for the curved manifold. I now have the straight ones (I made) which calls for 135's so that's part of the issue. Plus most likely prop isn't loading the engine enough so need to add a tad more pitch also. Probably too little pitch is the reason it will idle at 1250 smooth.  I couldn't believe it when I went down to idle and it settled on 1250 and sat there purring. But at least I know I got the wiring correct and oil pressure came up to normal pretty quick. Always a little tweaking to do to get everything set just right. I'll wait till I get the new jets before I do anymore run-ups. But so far, NICE!

    Bing carb jets
    Anybody know offhand if Bing jets for the 64 carbs are the same as the 54 jets? Od course the numbers will be different but are the threads the same?

    Well the HKS fired up and run! Smooth as silk. Did have some EGT issues to work out. But a smooth running engine. EGT's are running way too high. Since I changed the intakes and brought the engine to a higher climate, re-jetting might be in order. Easy starting. Smooth idle at 1250 RPM which tells me to add more pitch to the prop which goes along with high EGT's.

    2 hours by yourself, that's a no-brainer!  It will take that long to get it tweaked the way you want it.
