I was small engine mechanic today

Was raining outside so I thought I'd screw with my parents Mantis tiller to get it running again. I took the carb off and sprayed it out with carb cleaner, dumped out the gas tank & put in new, and did some other things. I still would only run at 1/2 throttle and die out at anything above.

I thought the gas line I replaced only 2 years ago looked funny, so I took it with me and bought some new gas line and a filter based off the old one. Turns out the gas line shrunk to about 1/2 the inside diameter it used to be, so it just plain wasn't getting the gas it needed and would die out because it was too lean. I put the new line in with the filter, and she runs like a raped ape again. Funny little tiller though. It gets the same treatement as all the other small engines, but this one is just plain finiky. Almost every year it needs a tune up because it doesn't want to run right. None of the other have given even a glimpse of trouble.

Is it that clear plastic/rubber fuel line??? I have yet to find any of the clear that will not shrink with time and alcohol fuel. It seems to be worse with ethanol but the methanol seems to do it too. I replace the lines on the chainsaws and weed eater each year. Just as fast to do that as worry with them out in the wood/yard not running.

The black rubber lines are bad about the insides falling apart while the out side looks good. Had my hand mower do that to me a few years ago. One year old black line was completely plugged up on the inside. It was Gates better line too.
 
It's a green color that's transparent. I was running premium no ethanol in it, so that's not to blame. Just cheap line I guess. I bought 12", needed 6". We'll see if I can find the extra next year when it's time to do it over again.

And to Todd- That screen is one of the first things I looked at after taking the carb off and just hosing it down. It was fine, but I just took it out anyway. I don't think I have to worry about it starting a garden on fire if it backfires a little bit.
