I'm sure we have some great small engine experts on this site, so with the Great lakes blizzard fast approaching I'll now ask for help...
I have a 8 year old Craftsman blower with 9.9 HP Briggs OHV winter engine. It never really ran very well from day one. Always starts just fine, but it now requires full choke or it coughs, pops and sputters continuously. With the choke on it seems to run ok but seems just a little down on power. It's obviously lean off choke. It has fairly fresh gas in it.
I've been through the carb at least 3 times, and it's as perfectly clean as I can get it using clorinated solvent and agressively blowing it out. One time I actually risked it and went ahead and bent the valve tab on the plastic float to attempt to raise the fuel level. It actually seemed to run better briefly, then the need for choke returned. The carb has no mixture screws.
Do I need a new carb?
Another problem cropped up 2 years ago. It stops driving intermittantly in any gear, forward or reverse. I've had it opened up, changed the drive belt and friction wheel. I've cleaned the friction disc and made sure the drive box was completly oil free. This machine has the spilt axle with differential. When it stops driving, if I rock it forward and side to side it will pick back up and drive like no tomorrow...then without warning just stop.
Could this little differential clutch be toast? Do they actually fail?
Any Ideas on my issues? The machine has little hours on it and looks like new, but I'm so frustrated with it, I'm looking longingly at any new machines in the stores on display at the wifes dismay.
Cheers, Mark

Mine is 2 years old, used less than 10 times, and I have the same drive problem....it always goes again, I had assumed a new belt would fix it......maybe not?
The governor might be out of wack. Mine rotor tiller started fine, then the engine kept running worse ... sputtering more & more the warmer it got. My B&S engine was running at too low revs. The governor return spring was stretched. I put a new one on and no probs. It was like a new engine!

I just looked under my desk and it's not there anymore. I think I mailed it to you just after my vacuum cleaner and garbage disposal stopped working and just before Mrs C!!!'s microwave and whirlpool stopped working. OOOOldtimer's disease confuses me sometimes.

Remember, "The Government" only has money confiscated from us.
If it has a gas shut off valve on the tank,check it out,sometimes there is crap from the factory that clogs it up,,i hate those carbs with no idle/or main mixture screws.Make sure the vent on the tank cap is clear also,try it with the cap off(cant have much fuel in it or it will splash all over) maybe not letting air back into tank?? just a few ideas,good luck!
These engines were designed toward meeting the strict EPA rules which took effect in the year 2001. Many of the things that we had in the past, such as adjustable carburetors, are now gone. These engines run learner and cleaner than anything before and it will become very important for the equipment owner to keep fresh fuel in these units. With smaller fixed jets and precision metering, stale fuel problems will cause erratic engine running or no starts. With proper maintenance their simple design should give years of trouble free service. The Intek engines come in six design names in the single cylinder models and for now, one in the V-twin.

I am willing to bet you are using regular fuel. Try running super in it. Regular gas with ethanol just will not get an older Briggs to run properly. Also check the gas cap to make sure the vent hole is not plugged.
Just had a friend here at work complain about same issues with your blower his is same age and carb.He is drilling the main jets or something to cure the lean issue,once i find out what he did i will share it with you, Did you get yours going?

Well, it does run, still needs pretty much full choke. Still have yet to put the non ethanol premium fuel in. I'm hoping it is a fuel issue, as there seems to be more ethanol in more fuels types today. Interesting theory though on enlarging the main. It's the drive on this thing that really has me baffled.

I'll only run "HIGH TEST" in any of my garden equipment. After seeing what the ethanol does to the fuel systems I see over at local farm quip. dealer & what happened to one of my car club members carb [ate the fuel bowls right out of his Holley carb] this "crap" they call gas is a JOKE. Causes more "GRIEF" than good, it will also "EAT" the lining out of a re-sealed gas tank or a coated tank from the factory!!!!!!
