Just for your consideration. As I said, I cleaned the troy bilt blower carb in the uc with a solution of harbor freight degreaser cleaner (the yellow green stuff in gallon jugs). I filled a jar with cleaner, dropped in the carb, and immersed the jar in uc filled with water. Experiment was not a...

Yeah, my previous post SHOULD have said "I've already used acetone...did I screw up?" 😄😄

I checked. He had a walbro wt-6 but mine was a zama. Both the throttle and choke levers are on the same side on the zama. On the walbro they were on opposite sides of carb. Thanks for the suggestion. I finally found a replacement nos on ebay. But it was from an unknown seller, and I don't know...

I did use compressed air on the initial cleaning of the homelite, which could have caused damage as I later learned on YouTube. Temp for cleaner on both carbs during ultrasound was 35 degrees centigrade.

I think there is some ongoing discussion about advisability of using an ultrasonic cleaner to clean chainsaw carb bodies. Here is my recent experience. This week I decided to tune up a homelite 240 chainsaw and a troybilt tb430 leaf blower that have been lying around my garage. Both of them...

Will acetone hurt a chainsaw carb? Thinking of immersing a carb body in a jar of acetone, then putting it in an ultrasonic for about 15 minutes. I'm wondering about possible damage to check valves.

Good job on shed, metsa. It will serve you well for years, I'm sure. And it certainly is an improvement over dragging everything from the garage to the tailgate of a pickup truck with an extension cord for power, which is my current workshop! How do you like the dremel drill press? I'm thinking...

Man, why all the animosity towards project farm? The man has accumulated quite a following with his reviews, so he must be doing something right. He provides a valuable service and seems to be having fun doing it. Usually his methods seem to make sense. I enjoy watching, and hes saved me from...

How do I check if the timing is correct on a 2 stroke? The coil is fixed, as are the magnets on the flywheel. What could cause the timing to be off, and how would I detect that?

I fired it into air, and I also used one of those gizmos like a spark plug wire with a plastic bulb in line that flashes to show spark. Is that a spark tester like you're referring to? Both methods showed strong spark.

OK. It's not a sheared or bent keyway. It has great spark. I tried taking out the muffler screen earlier. I even tried starting it without the muffler because it has some honeycomb type material in it. Still wouldn't start. Timing of spark might explain why it is sounding like it does. I pull...

Thanks. That will be a new area of troubleshooting for me.

I acquired an echo pb250ln blower that won't start or run. It has good spark, 135 psi compression, and vacuum and pressure check okay. It will sputter and want to run for one or two seconds, but then dies. Sometimes it backfires. I figured carb problem, so I bought a hipa new carb, lines...

Thanks skeet. I went ahead and bought a new cylinder and piston off Amazon. Works great now.

Yes. New plug.

It's kind of a bluish white.

It's got regular spark. Is it possible the spark isn't strong enough?

Okay. New compression gauge arrive. About 130 psi, so compression is not the problem. I put a new hipa carb on it, and spark plug is getting moist, so fuel is getting in. It will sometimes sputter and want to run for a few revolutions, then die. Is pressure checking the seals my next logical...

I picked up an echo pb250 blower at a yard sale. It has spark, and carb seems to be working. I pulled the flywheel to make sure the key hadn't bent and upset the timing, which was an issue with some of these. My compression gauge broke, but the compression did seem low, so I pulled the cylinder...

I think people who use motor oil tend to use drained oil, which would just go to recycle tub. So essentially it's free.
