Any small engine gurus?
Model: 281320BE (Snapper)
Engine: (13 hp signature series)
Walbro - 5-4993 LMT (Only other number I found was 57 on top of Carb)
What I've Done since purchase:
New Air Filter
New Fuel Filter
New Fuel Line
New Spark Plug
Ran fine yesterday for hours, although power isn't what it should be.
Today I fueled it up, ran fine for 15 minutes or so, then it cut off, and I noticed gas was seeping out the vent of gas tank. The tank was not overfilled. Took cap off, ran for a few seconds then cut off. Cranked a few more times, and ran for a few seconds, then cut off.
Took the carb off, there is no LMT number to be found on the carb, which is apparently the majic number that the whole carburetor world hinges upon, but there is a 57 cast into the top of the carb beside the B&S logo. No record of a LMT 57 with B&S, so not sure what carb kit I need.
Took the bowl off the carb, and there was a yellow powder substance on the internal aluminum housing. One of the 2 holes in the bottom of the aluminum was clogged and the other was partially blocked. There was a little trash in the bowl. Blew through the ports by mouth just to see if air was passing through. Put it back together, and it cranks and runs. I finished cutting the yard, but the motor lacks power.
A couple of questions that I have:
How do I know what carb I have since there is no LMT # anywhere to be found on the carb , so I can order a kit if needed? How do I know what replacement carbs will work?
How do I adjust the carb, and will this give it more power? The engine doesn't seem to rev up as high as it should at wot. Also, I had a snapper a few years ago with a 11hp, which was a brute. Since this one is 13hp, I would expect it to be even more powerful. My 11 hp would pour on the coal when it got under load, but this engine seems to lose power.
Thanks for any advice and help.
