Free walk behind blower

[FUTZ]

There’s a guy in-town who calls himself a small engine repairman. He’s kinda a ran-when-parked repair guy. We’re sorta friends, well we talk tractors together. He “fixed” this blower; looks like he had engine out and split it. It didn’t work after he fixed it and he wanted it out of his sight, so he gave it to me. He said it rev’d out of control. I started it and it only idled. It’s supposed to run at constant speed; there’s no throttle lever. So the governor doesn’t work. Probably assembled wrong. I screwed in the idle speed screw until it was running at about 2000rpm. I used like this for one or two seasons. At beginning of next season I took carb apart. It also had been assembled wrong things were bent and there was no mixture orifice???? I bought a new carb. Then it wouldn’t run unless the choke was 3/4’s closed. So the new carb is too small, it was too lean. I ran it the rest of the season like that. It work okay for the few snow falls we got, but having no governor, and 3/4 choke meant little power. It’s not worth fixing, but I was intrigued. I thought adding hand throttle would fix governor problem and drilling out orifice would fix mixture problem. Never fix two problems at once. When I put on throttle lever, I backed off the idle to about 1000rpm (remember it was at 2000). I drilled out orifice but still needed choke. I should have tested at high speed. I drilled it out some more and ran without choke. Now when I rev up, it blows black smoke, but backfires when I back off throttle. Therefore, it’s too lean at idle and too rich at high rev. I should have tested it more before I drilled out jet more. I guess I could solder the high speed jet and re-drill, but I don’t know how to fix idle mixture. There no idle mix adjustments on this carb.

Thumb throttle

Snow column looks more narrow from operator position.

Bracket for direct butterfly control

I should just fix my CASE.
