Hello T, Back when I started in the late 70's we actually learned how to perform reliable overhauls and parts were abundant for reasonable prices, so it was practical. Of course, we were usually trained by more experienced elders who were around in the cast iron engine days. Now, no one is...

Take the 1/2" head bolt out (near the breather tube) and remove the entire tank and carburetor, then the carburetor will lift up off the tank if all the screws are out. Watch for a spacer to fall out between the tank and engine block.

Hello P, The question now is why did the fuse blow? It may blow again.

Hello P, Worse case: New engine is roughly $1200 plus whatever labor to install. Even a good local auto mechanic might be willing to fix the original engine as a side job for the extra money. Finding a competent small engine mechanic anywhere these days is next to impossible. Dealers have...

Hello John, Have you looked down into the plug hole to check the cylinder for scoring? You can also remove the muffler to actually see if the side of the piston is scored. Are you using the correct number spark plug it calls for and not just one that fits? Are you using a different 2-stroke...

A couple of pictures would help. You should not have to pry on anything to get the carburetor off.

Hi Tim, I am not familiar enough with that particular carburetor to make suggestions on what will work or not. Of course, as the saying goes.... Nothing ventured is nothing gained. I hope you succeed. Worst case, you will need to search for a complete carburetor.

Hi Sarge, People like to hammer on Walmart oil (Reminds me of the K-Mart era) Walmart strategically shops distributors and purchases in bulk to help keep prices down. (Cheaper does not mean an inferior product) Here is a link for this who are interested in learning...

Hello GS, It is a matter of reading the label on the product (with a magnifying glass) or looking it up online to understand the product you intend to use. Way too many people rush through a repair by skipping over the needed cure time. I simply ask why rush?

Read my reply #4. Sorry it happened to you.

Is it the pin that broke? Pictures would help us to understand wat you are referring to as the "strut".

Hello Mac29, Mount the tire on the rim with a new valve stem, then put a ratchet strap around the tire in the middle of the tread, sinch it down a little. Pull the tire valve center stem out and apply slight air pressure to seat the bead. Tighten the strap down slowly until the bead seats. As...

For folks reading this thread, I ask you check out You Tube videos by Lake Speed Jr. He is an oil engineer and know this stuff backwards and forwards. Everyone has a favorite or a long-term brand that they have trusted for years, but the science has not changed, it has improved by leaps and...

I think the port without anything connected is actually a bowl vent to atmosphere. Most have a simple hanging line coming off of them going down to nowhere. The line routing looks questionable, but I don't have any diagrams to give direction. From your description the float needle has trash in...

I have seen this exact same coating when a customer had diesel mixed in a fuel can. I ended up using Chemtool B-12 carburetor spray to finally cut through that stuff. Diesel fuel requires much high combustion pressure and temperature to ignite, if not what you end up with is a sticky polymer...
