Fabbed a header for the junkyard dog.

Found a piece of 1" I.d. Pipe in my junk pile. Had to oval it at the front to weld it to the mounting plate so I could get the cap screws in. Now my question. With the high flow air cleaner and header will I have to reject the carb on the tecumseh flathead?

No, you won't have to reject the carb if you don't want to, although, you may want to rejet it.

No...

Looks nice... If you end up getting lots of back fire try 7/8 pipe... Or just add some sort of restriction to the 1 inch...

Are you running lean now, with the pipe? Check your spark plug.

You should be running on the leaner side on account of your new free-flowing air cleaner...

I will run it and check the plug tomorrow. I have been googling and no luck trying to find a way to put a bigger main jet in the carb of the 5hp flathead tecumseh. Any info is appreciated.

However, a set of micro drill bits and the manual bit holder called a "pin vise" might be the answer. Gradually drill the jet out going up in sizes one by one, then test it, drive hard, note the results...

Thanks Hellion. Got a bookmark.

And if you drill it too big, you can always fill it with solder, and redrill.

ETA: There's probably an app for that!
