Engine start to run rough and shot off after 3-4 minutes running


Possible solutions:
You could have water in your gas if so a $3 additive will unfreeze and eliminate this which will cause rough idling. If your carb is clean make sure to let the blower warm up for several minutes, take off the choke as it warms and it will run smoothly. Last if those dont work, adjust your carbs mixture setting screw (when the engine is warm). (and check your oil! Hope this helps.

Carb. needs to be rebuilt. If your choking the engine it to keep the alive and you've cleaned and replaced everything else, I would recommend carb. overhaul.

TILLER LOPS. WONT RUM SMOOTH WHEN TILLING GARDEN ENGINE GOES UP & DOWN IN SPEED


For a quick and easy fix, try adding some Fuel Treatment to your fuel as it sounds like the carb is dirty. I recommend Berryman Chem Tool B-12. The dose is 1 ounce to a gallon of gas. Double that, or just add a little bit directly to the tiller fuel tank...if this is a 4 stroke engine. If this is a 2 stroke, don't do this as the oil in the mix will be too cut by the solvent in the B-12. Carburetor disassembly and cleaning will be required on a 2 stroke tiller engine. Clean that carb ONLY with WD 40. Don't use any strong solvents on the internal carb as it can swell and/or distort the sensitive check valves and mess up the carburetor permanently.

Problems with RC engine not running right!


Theres a idle screw located on engine under airfilter, should be small flat head. Clockwise will stop the carb from closing thus not cutting engine of. Also make sure you run car slightly richer than leaner. Hope this helps.

Engine is surging.


hi,

sound through experience you have a air leak possible from a gasket or oring if so equipped. take some wd 40 and spray around the carb gaskets and seams. if this stabalises the surging or smooths it out it is definatley seeping air around it. in any case you will most likely need to take the carb back apart and repair or replace the gasket. hopes this helped. happy mowing!
