So frustrated with Craftsman 25cc Gas Blower not starting - model #358.797170 - 2 Cycle
I have made another post on this piece of machine and starting issues, but am writing a new one to summarize all I have tried to do to get it to start/run. I hear many say Craftsman gas tools aren't made like they used to and are trouble now. I tried to not believe it, but honestly I'm starting to agree. I got this gas leaf blower used cheap and tried to fix it. I would've left it where it was if I knew how much trouble it was. :(
This seems ridiculous that it won't run. Here's what I have done to date. I'm out of ideas/options.
- Changed spark plug - uses CJ-6Y
- Rinsed/cleaned foam air filter - looks fine
- Had to tighten engine block as two main bolts seemed a bit loose probably causing compression issues. Totally fine now. I'm not sure how to check pistons/gaskets, but...
- Completely cleaned spark plug arrestor screen - it was completely caked over with 0 clearance - used wire brush - now looks like new
- Total rebuild of Zama Carbeurator - model # C1Q - W11C 36A. Bought new rebuild kit (RB-47) and replaced all gaskets. Did carb cleaning too.
- Installed new fuel lines. Installed new fuel filter - I did have to enlarge the gas line hole in the tank slightly that accepts the fuel filter as I couldn't find replacement line that matched the old. It's now the same diameter as the fuel line that goes to the inlet in the tank. Lines are tight - no leakage out of the thank.
I checked compression with a tester. Three pulls showed 110, 130, 150...I thought 90+ compression is enough to start.
I used a spark tester. Lit up just fine. If I put a little starter spray in the carb, it'll turn over, but die out.
When I push the primer bulb, it fills up with fuel easily and depresses just fine.
I have no idea how to adjust H/L settings on carb.
I mean geez....what else is left? I won't put anymore $$$$ into it as it's not worth it. It's not that good of a unit. :) However, I did invest some so I hate getting nothing out of my investment to date.

All you need to do is replace the carb. No matter how many times you try to clean and/ or rebuild these carbs there is no way to unclog them. Believe me I have tried soaking in carb cleaner, used mechanic in a bottle ( which btw is great if the carb is dirty amd is hard to start. Once a little dirt gets in the carb there is no getting it out.I tryed completely disassembling the carb, replaced the needle valve asy, screen, jet and all other parts that come in the rebuild kit. For about $25 you can buy a new carb and it will start and run great
