Hi all, I'm going to buy and install this kit: to my engine. Is something, that I should be careful on? Has engine better performance with this carb? i also need to know, what is height of whole assembly, because I have only 22cm from original air intake manifold to the hood. I have no nerves with original hitachi carburetor, needle valve from float start leaking, and no repair kit is in any shop here. I think they stop making it. So Weber will be perfect solution for me and my plane. What do you think? Is here someone who has this kit on his engine?
