Identifying a Walbro Carb on an older Ryobi String Trimmer
I have a quite old but very reliable (till now) Ryobi Professional Model 2079r String Trimmer. I have been using this thing for going on 25 years or more. Other than air and fuel filters, a new gas cap and several bump heads that I use till they stop holding line, it is running with original parts.
Past couple years, it has started acting up where if I run it for a while then have to stop to add line or fill tank, it won't crank back up for anything. I figured there was a vapor lock happening somewhere in the carb and lived with it. Well this weekend, it would not run. Tried to start over and over and it would hit a few times after hitting the primer bulb but then fizzle out. So I am confident it's a carb problem and that's where I am running into a problem. It's a Walbro carb but I cannot match the numbers to an actual Walbro part number.
The prefix letters,"WYL" are stamped into part of a flange then a little below that on the body are the numbers "51" and right below those numbers are "913". (I can post a pic if helpful) Well the combinations WYL-51913, 51-913, 51, 913 don't match up to anything. The closest I can find from the Walbro site is WYL-19-1 or WYL-191-1 but that has the extra "1".
Ordering parts or a new carb from Walbro is kinda prohibitively expensive so am looking for a kit or replacement carb on Amazon but without being able to verify the model, I am hesitant to order something that, while looking like a match, may be slightly different internally.
Any thoughts on how to confirm which carb I have ?
Thanks......
