I don't really know the type of carb you have, but Yes you can fix it to a certain degree on the engine as long as you have access to the float bowl... 1).Remove the spark plug from the unit (safety first). 2),Shut off or clamp the fuel line to the carb. 3).Remove the air cleaner assembly from the carb (easier access). 4).Remove the float bowl nut (gas will come out use a rag to sop it up...). 5).Gently pull down on the carb bowl,note there will be an o-ring gasket on the top of the bowl(bowl gasket).Inspect what you see in float bowl ie.water, dirt, rust etc.) 6).Once the bowl is removed ,you can see the float and float needle valve . 7).Remove the float pin .(pivot point, carefully) 8).The float needle valve will come with the float I believe...look at the float needle and see if it has a ring around the tip of it ,if it does it is worn,and needs to be replaced (the float seat may also be replaceable but without knowing what carb you have I am not certain) your small engine dealer can tell you that info. 9).Shake the float ,gas inside ,replace it ! 10).Where the float needle enters the needle seat area ,blow compressed air or carb cleaner to blow out debris . 11).Check bowl nut for debris and clean . Other issues can be a misadjusted float,plugged atmospheric vent .... Reassemble in reverse ....good luck Jim

Rusty, Is it beneficial to polish the top of the piston and inside of the head? Would you use furniture polish, car polish? Are you serious about the diaper or just joking? I just had a new neighbor move in with a baby. I wonder how the "Hi, Welcome to the neighborhood. Can I borrow a diaper?" will go over? Hmmm, maybe not :)

It seems by the time you would repair one correctly (hopefully) they can still bite you on the backside. The little o rings are pricey for the tube- some have 2 on the tube alone plus the one below, plus the gasket and then when your done, you end up still wanting a better repair. It's great to know Rolm got it the first time. Most techs have learned the hard way and do what networker said. One does have to be careful that they get the right kit. I've grabbed one that was on the QR chart I grabbed somewhere and it was wrong per the parts list. Part of this, I believe is a lesson on some people and carb cleaners. If I come across one that has badly deteriorating O rings, I wonder how much cleaner is in the tank. Always best to clean the tank and flush or replace the lines.

OK, tackled the beast, found the bowl free of sediment and crap, what I expected due to running it dry, etc. The main jet seemed to be partially plugged, so I gently reamed it with a very fine gauge wire. Now I could see through it, before, not so well. Sprayed everything well with carb and choke cleaner. Also gave a few shots down the throat while the air cleaner was off. Reassembled, drug outside in the rain and it started right up. Smoked billowed, due to the carb cleaner then it settled down. Seems to have much more power at full throttle now, so that's a good thing. Still hunts, and now only wants about quarter choke to idle. From what I can discern from the Briggs diagram, the idle jet is inaccessible. I'm suspecting that it's partially clogged. While apart, looked for a good place to put an inline fuel filter. I have two types in my stock. One is about the size of a golf ball with long barbs, the other is about the size of ...three fifty cent pieces together with short barbs. The way the fuel line runs, neither would work. If I get ambitious, I could reroute the line out the right side of the carb (viewed from the rear) and put whatever I want there. That's a big IF.... :-) Mike, intriguing idea, I don't have any MMO in my barn, don't know why, have everything else. Going in town tomorrow and will pick some up. So, in conclusion, I learned more about this "EPA blessed Carb" and based on the way it acts now, the main jet was partially plugged. Still wants to be choked to be happy. Guess I can live with that, when I'm doing heavy tilling. For the light stuff, have a Mantis and a 10 year old Sears 2cycle which I can't seem to kill. Thanks for all the good input!!! Ev
