Hello everyone,
I have a question about a Mantis Garden Tiller, model 7222M, with a Zama carb C1U. Anyway, this is a customers and it is having a really hard time starting. When I received it, I decided to clean out the carb and actaully cleaned it out two times in a row. Anyway, it took me a while to crank it up and after adjusting the low and high speed adjustment needles it actaully ran Great!! so I took it up to t he graden to till up the grass/weeds that are growing around the vegetable plants. Anyway, after it ran for about 5 to 10 minutes and I came back off full throttle i would not idle anymore and would not crank back up for me. So that is why I cleaned the carb a second time and the same thing again, hard to crank but once cranked ran Great for the first 5 to 10 minutes then died when comming back down to idle speed. So what I have done is replaced the fuel lines but this was before the two carb cleanings so the fuel lines are good to go. Now, tonight I bought a Zama carb rebuild kit and it will not be here until sometime the middle of next week. The exhaust is soaking in carb cleaner to remove carbon deposits. When I removed the exhaust it had some fuel sitting inside of it and the piston had some fuel on it also when I went to pull the pull rope and saw some gas comming out the exhaust port when the piston was moving up and down. So my question is do you think the carb rebuild kit will fix my issue and will replacing the spark plug with a new one help also? I also checked the manifold bolts and there tight and I also checked the two head bolts and there tight. Should I replace the carb to intake gasket. The old one looks good but maybe I should replace it as well. Thoughts....
