My grandpa always said “They’re called golden years because it takes a lot of gold to stay alive.” He had a lot of lung issues stemming from painting cars back when paints had more harmful volatile compounds (1950-60’s).

These are mean when ported well! I am an owner of one (porting and machine work done by yours truly, not Krafterized).

No it won’t. But it should crank over with voltage fed straight to the starter. Make sure the engine turns over easily by hand by rotating the top flywheel screen.

That’s older than any FD I’ve ever worked on. What a weird setup! I would suspect supply voltage to the igniter. I’m sure it has a 12v feed wire somewhere. Find a mower wiring diagram and do some testing.

I think the tigger has an adjustment screw in it on that model. Backing that out a couple turns means the throttle cable won’t pull as far, which of course will limit power, but it should mitigate the rev limiter use.

Could you post a picture of the igniter? Most of the FD engines have a 12v supplied ignition without an igniter. FC series is the only one I can think of with an igniter like I was talking about, but this may be a really old FD with a similar setup.

If there is a high adjustment, it is under a small plastic plug in the side of the carburetor body. The low adjustment is in the middle of the throttle rotor. Not all of those carbs are adjustable—if you post a picture I can tell you if it is or not.

The ramped intake side transfers on those cylinders are weird. Some people square them up and turn the roof into a normal flat profile but I use a flat ended diamond burr in a dremel to evenly grind the roof to maintain the angle. As far as right angle hand pieces, I found that high speed...

You’re in the minority. Not a lot of love for Ultra around.

Is this a single cylinder engine and what model engine?

I had a 550 with a bad coil that acted like this. Put a fresh plug in it and it would start once and run okay but then flood the next time it was started. I chased the carburetor first, but it was fine.

We’ve sold tens of thousands with absolutely zero issues. But those are definitely genuine, purchased through a distributor.

They are excessive for small jobs. I wonder how soon it will be until we see twin pipe blowers. Echo toyed around with that many years ago but didn’t pursue it past the prototype stage. Two smaller, more maneuverable tubes would make the 9010 a lot more practical.

What you’re describing sounds like a pitch mismatch. If the chain is made with too much/little distance between the rivets, the bottom of the tie straps and sides of the drive links get burred and seize up. More oil won’t help that.

Supposedly it was planted along the interstates as erosion control before it was deemed too invasive. Are you close to an interstate junction?
