7222 mantis wont start without starting fluid. Does the metal side of the carb diaphram go up or down

SOURCE: 2 cycle mantis tiller leaks gas thru the carb. -

if it leaks gas,it can **** air.you have to find out whats leaking and stop it.

SOURCE: trouble starting old Mantis tiller 9012 - don't have a manuel -

Mantis has the owners manuals in pdf format available for download on its website. The tillers are here (I hope the link to the tiller group works...if not, just go to the main site and look for "owners manuals" link.

Also, you can call a number and get a representative who usually can help at the numbers listed there, find authorized service people if its not something you can do yourself, order parts and find detailed schematics in the owners manuals. My dog actually ate mine. LOL. But they are free, the owners manuals, unlike other places that charge you for them like they were a "part".

Sounds like it's flooding either from over choking or the inlet needle in the carb is leaking. Have you removed the plug and blown out the cylinder and plug with air and then tried to restart? Be careful not to keep cranking with the choke pulled out. When it 'hits' ONE time, move the choke halfway in and crank again

SOURCE: tiller wont stay running..

Clean out the small fuel inlet ports behind the diaphragm. Sounds like they are clogged up. Use the end of a paperclip to gently make sure the passages are open. Hope this helps. Good luck.

Two cycle engines must have a completely sealed crankcase to work properly. When the crankcase is sealed, the air to fuel ratio is set by the carb to optimize the operation of the engine. You can try the carb adjustments, I'd suggest backing out (counter clockwise) the high speed jet, if it has one. If not, it's a fixed jet and you'll have to disassemble the carb to clean it. If your engine on runs best with the choke on - the air to fuel ratio is messed. In other words, either you have a restriction in the carb preventing the engine from inhaling enough fuel and you're using the choke to get the right air to fuel mixture OR by restricting the air intake (putting the choke on) your engine is getting its air needs from some other place, such as a leaking seal or gasket in the crankcase. If you run the engine like his for long, you run the risk of burning up the cylinder and making a boat anchor out of the unit. A two cycle mechanic would do a pressure test on the crankcase to check for air leaks. If you're not able to have someone pressure check the engine, your best bet is to look for loose screws on the cylinder/crankcase - and to make sure the fuel delivery system (fuel filter in the tank, fuel line, and carb diaphragms) is in proper condition - replace the filter if dirty, fuel lines if mushy, and put in a carb kit. If that doesn't fix it, you've likely got an air leak that's going to require a mechanic with the proper test plates to find and fix.
