Engine rpm serges sometimes and powernosle pressure drop some times

Gas engine surging and losing power sounds like dirty carb to me.
Pressure washers are often used and then sit for months before being used again. This often creates blockage in carb passages. If you have or install a fuel cutoff valve you can reduce this problem. When you are done pressure washing, turn off the fuel valve and continue spraying water until the carb empties ( the engine will sputter and go out) Next time you want to wash turn on the valve and you should be good to go.

Engine serges

Does it idle properly? If it idle properly and surges when you mash on the gas,you have a fuel pressure problem,you will need to measure the fuel pressure it has to be at 35psi to 45 psi

Needle Broke/Not Serging Properly

I haven't tried this to make sure, but my best guess (5 months late...) is that you are serging with three threads and that when you replaced the broken needle, you mounted the needle on the left mount. If you are serging with three threads the needle needs to be on the right.

The fourth thread goes through the needle on the left and provides what looks like a straight stitch. The lower looper catches the fourth thread underneath the fabric, but the upper looper does not reach it on the top side. If you use the left needle, but not the right one, I imagine you would only get a straight stitch.

Another guess is that you replaced the broken needle with a standard sized sewing machine needle. The 5280E uses a shorter needle. (DC x 1F). If the needle is too long, it may not rise high enough to loop with the upper looper properly. It probably still catches the lower looper and leaves you with a straight stitch.

I hope you solved your problem a long time ago. If not, I hope this helps.

Letture leaf edging

From "Serge With Confidence" by Nancy Zieman:

Set the machine up for a 3-thread rolled edge. Normal width; length 1 - 2.

Use Woolly Nylon in the loopers & regular thread in the needle.

Lock or disengage the cutting blade.

Guide fabric along the right edge of the presser foot.

Stretch and equal amount from fron to back while serging.

Lower the differential feed, if available to about 0.6.

Serge at a slow to moderate speed.

Practice with scraps first.

After serging, gently stretch & release the fabric edge after serging.

Idles nice but when i go to drive it sputters and chugs and serges what is going on? also having difficulty getting it to start have to turn switch back and forth until it starts. Also I lost gas cap does...

try replacing the gas cap first and see if it helps any, on some vehicles, the fuel pump builds pressure inside the tank so it has the correct amount of pressure to send the gas to the engine. if the cap is missing, it can't build pressure.
