I have never been a fan of fuel stabilizer, nor used it. Fresh fuel with zero water in it is the way to go. This topic is another controversial one like ethanol debate.

Make sure the engine has oil and it is at full mark. If you want to add a little oil down spark plug hole and crank it over a few times, nothing wrong with that at all. Remember that long term engine longevity for your engine is regular maintenance including oil changes, checking oil, and...

Don’t forget the emulsion tube, pilot jet, and main jet also getting blocked partially or fully is what mainly leads to hunting and surging. It is normally lack of fuel (running lean) that causes RPM fluctuation. Occasionally it can be air leaks in intake gasket, etc. Rarely is it a governor...

You can also put a wooden Q-tip with valve lapping compound on it and chuck it up in a drill at low speed. Then switch to carburetor cleaner, then blow out the seat.

Oregon and Rotary are simply distributors, selling aftermarket and sometimes OEM parts.

It is a Nikki carburetor from the looks of pictures. If you can’t tell a pulse fuel pump from an electronic fuel pump, I would suggest going to a shop for help. Why would an electronic fuel pump be on a carbureted engine?!

How many people actually remove a cylinder head every once in a while to decarbonize it? Way less that even remove the engine shroud to check for dirt, debris on cooling fines and top off engine. How expensive do you think it would be to buy a used cylinder head off of EBay, remove the one on...

If the engine running on one cylinder was your first thought, why would bypassing the governor make it better? Address the issue with why only one cylinder is running and do NOT mess with the governor.

Charge battery, 12.05 volts is flat. Remove carburetor and address the leaking needle and seat issue. Install fuel shut off valve for backup.

Helicoils are normally very reliable long term if installed correctly. Who would go to the trouble of removing the cylinder head, welding it, tapping a new hole, probably have to replace head gasket, and reinstalling cylinder head? That sounds like something they would do in Pakistan.

I buy several 5 gallon buckets of Citgo 10W-30 locally at place that sells lubricants. The local Walmart became to unreliable on stock availability as well as cost and quantity I was needing.

One of the main reasons yearly maintenance prevents most problems is because you usually catch problems before they happen. Example: A drive belt that has cracks about every inch and needs to be replaced. Very few people seem to do yearly maintenance with their equipment, at least in my experience.

Many times when removing spark plugs from customer engines, I find the plugs to be too loose. I think they are afraid of stripping it. Anyway, I have two engines with stripped spark plug threads and one engine with stripped carburetor bolt threads I will work on this winter. Occasionally people...

Probably a worn and tired engine with a combination of worn rings, worn valve guides/seals, sloppy valves, etc. If you have time and money and motivation, go for it.

I burn spark arrestors out for customers occasionally right on the spot. Equipment can’t exhale when exhaust is blocked. Fairly common issue.
