Yes your carb. diaphrams could no longer be pliable due to the ethanol 10% fuel to say the least. ethanol is rubber diaphrams worst nightmare along with the owners
also check this if you havent
you have a muffler screen that also may be partially clogged
some screens maybe on the outside of the muffler behind a plate with screws and some behind the muffler which requires removal and you may not have one at all but it is wortha look see.
hope this helps?

I need to know the proper tuning of ucal mikuni carburetor with mixture adjusting screw on bottom of cabr (beneath float bowl), an idle adjust screw and pilot screw (hopefully pilot fuel screw since s

Why did you need to clean the carb? Routine servicing of the aircleaner would keep the carb clean for life. The pilot screw should be 1.5 turns out approx. with a small adjustment either way. Idle speed is set to a smooth low idle.If this doesn't fix it have you got something in the carb not replaced correctly? The float needle/float assy? How did you clean it? Have you introduced fluff/dirt into the carb and did you blow it clean with an airline?

Usually when a mower dies, it is a fuel delivery problem. Have you changed the filter? Is the gas fresh. Also has the air filter and spark plug been changed recently? the Carburetor may need to cleaned. Take the air cleaner off and spray some carb cleaner in the throat of the carb. Also, take about 1/3 bottle of carb/fuel system cleaner and add it to the gas in the tank.. For the new mower engines, there is no fine-tune adjustments on the carburetor. Also clean the exterior of the carb with carb spray.

Sounds like a fuel restriction. have you checked the fuel pump? Your carbs may also need to be cleaned, there are "circuits" and pathways in carbs that get clogged and need to be cleaned and rebuilt. when was the last time you checked the fuel pump or carbs?

4000 watt buffalo tools generator: Engine Starts, but after a few minutes it cuts out and stops running. No appliances plugged in, drained gas(it did sit for 6 months), oil is full, Plug is good.

Idle speed jet or passage and/or high speed jet/passage is clogged. Remove the carb and inspect and clean thoroughly, then re-install. Set idle and high spped screws approx 1 turn and tune to run smooth from there.

POULAN 200 mph blower. New spark plug last fall.

You will need to check the fuel lines for cracks/breaks.

You will need to disassemble the carburetor and spray with carb.cleaner. Make sure the small screen in the carb. is free of debris. Use a Den Tek Brush, (, to clean the small portals in carb. These portals can become blocked. Reassemble and start.

(NOTE: If the carburetor parts are more than four years old, and depending on the use, you will need a new carb. kit if the cleaning doesn't work.)

If you need further assistance, just let me know.

Engine is not running smooth

is it stalls in low idle?The truck probably needs a tune up, new spark plugs and wires, new air filter, oil and oil filter, then spray carb cleaner down the carb, or dump some cleaner in the gas tank as well..... most people ignore and neglect their cars, so when they die they wonder what happened. Get a tune up, she will run like new.
