KEXMY ruixing H619-6a 52cc Lawn Mower Carburetor

Spot on.

Blower had hard starts, ran poorly and stalled. Put the new carb on, starts 1st pull and runs like a top. Had to adjust the fuel a bit but it runs great now.

Run’s good. The rubber grommet fit’s loose and will probably leak over time.

Order came in a few days. Easy to install. Started on the second pull and runs great. I recommend using the "canned gas" rather than mixing your own gas/ oil mix...especially if machine is not used very often.

Great price, perfect fit. The cable attach bracket was slightly different but still connected with no modifications. Before replacement blower would not start. Spark was good but would not fire with priming into carb (to fix low/no gas flow) or wide open throttle (to fix flooding). Noticed gas in filter and when pulled the spark plug it was wet with mixed gas. Took about 10 minutes to install new carb and it now starts like new. Poulan Pro PR46BT backpack blower.

I made a mistake and destroyed the carburetor on my Ryobi RY38BP leaf blower (a gutter cleaning kit killed it, don't attach one of these to this blower). I can't find an aftermarket replacement for that carb. The impulse port is in an odd location, not matched by anything I could find. The Ryobi part, a Walbro carb, would cost about $50 shipped, and I didn't want to pay that considering that it's a $200 blower. This is a rotary throttle valve just like the Walbro and the throttle cable attaches in the same place. But the impulse port is way off, and the throat is bigger, .590 rather than .500. I made an adapter plate out of 1/8" aluminum stock, with the impulse port drilled all the way through where it contacts the intake manifold, and partway through where it contacts the carb, and made a channel between them with a small file (a mill would have been nice for this), and made gaskets for each side to match. I also beveled the intake port in the adapter plate to better match up the .590 carb throat to the .500 intake. I haven't adjusted the idle needle (and the plug is still in place) but it seems to be idling fine. The main needle as shipped was 2.5 turns out from its seat which seemed excessive, but putting it in one turn made it run very badly. I ended up with 3 turns out, or somewhere thereabouts. It's pumping fuel as it should and running very strong. Maybe even better than with the OEM carb. I was worried that the carb would be too big, but I don't think it is. And having an external high-side adjustment needle is a big plus. Note again that this is NOT a direct fit for the RY38BP blower. It took a few hours of work to make the adapter plate and gaskets. But next time I have carb problems, I'll just buy a new one of these and swap it out. You can't beat the price. It seems to be a good carb. If it's a direct fit for your application, you probably won't be disappointed. I just got done blowing for about a half hour. It died on me once and I don't know why. I pumped the fuel bulb a few times and it started back up and did not die again. It was blowing very well, moving mounds of wet leaves with no problem.
