3447 CARB REBUILD

I had my 3447 max wedge carbs rebuilt and found out some strange stuff. When I picked them up the fellow pointed out a couple of issues. One was someone installed an incorrect fuel inlet fitting on one carb. The fitting is entirely wrong and I should have had a massive fuel leak but I never did. The fitting was for the inverted flare type on the male end to carb. No idea why it didn't leak. But the big issue he pointed out was I wasn't getting wide open throttle. The linkage would hit on the idle screw and the butterflies opened about 90% on the primary and maybe 40% on the sec. I had to grind a little off the linkage arm where it hit the idle screw. Let's see if I notice any performance gain!

Sounds like something needed to bent, not ground off......

Nope. You would have to see it to fully understand that it was not a bent issue what so ever. I was once told to adjust the idle by using the large air adjust that these carbs have, tried it once and I couldn't do so. I've seen pics of other 3447 carbs that do not have the idle screw installed. So I don't know what is correct but I solved the issue of the linkage hitting the screws.

Here's what I was told 4 years ago, didn't seem to work for me then I noticed there were idle adjust screws and went that route. Now I find out they stop the throttle from fully opening. So now I believe the idle air adjust on these carbs is correct. Look at post # 5: MAX WEDGE IDLE ADJUSTMENT
