What carb?

I have an oddball setup I need to fix. Someone put a carb on a 5hp tiller engine that is to far between the manifold bolts.
It is on a 1qt. tank and is held with four screws.
Anyone know what carb would fit right?
The tank is all ate up, but still holds gas in the well and tank.

Newer engines had 1 bolt spaced farther from carb bore. A different gasket is available with both holes. Block needs to have this 2nd hole to accommodate this style carb.

Very good chance your block is setup for this for you to make it work.

Most fun power carbs are like this.

The air filter is different between them also , the pull choke and raptor carbs have a long through bolt .
The fun power have two small screws holding the cover on .
 
If you've got an older block, (which it sounds like you do,) it will not have the wide bolt pattern intake flange. You will need to find a PN 397135 carb or similar (Raptor, pull choke, butterfly choke etc.) The Raptor carbs do not have the provision for the EPA return and stock air cleaner, but you can go with an aftermarket (K&N style) air filter easily enough. I probably have a couple hundred carbs here that would work just right for you, but likely you can go to a local lawnmower repair shop and ask if you can pick through their scrap pile and pick up one for free.
Often times craigslist and facebook marketplace list things called "curb alerts" that are free for the taking. You'll find complete tillers, mowers, etc that people just want rid of - if there's one good part that you can use, it would be worth the trip to the scrapper with the rest. :)

Hi, the carbs you have, what sort are they and what price shipped?
I can tell you that a push mower with no wheels, seized engine, stripped for parts, will be gone in a couple hours for scrap to pay for drugs around here.
 
The left is old pull choke . The newer butterfly choke ones have a cut out or depression where the cap fits . Both interchangeable .
The right is fun power

I have the 397135 butterfly choke style carbs, and I have Raptor carbs (simply a racing version of the 397135 without the air filter stud and threads and no epa return drilled (both could be done, but they are not final machined for racing purposes.)

Either of the first two carbs you have pictured will work fine.
