How do you change the primer bulb on a Tecumeh 4.5 lawnmower..I am having trouble starting this lawnmower..When you prime it when its cold,it will start and then quit right away.if i start it again and prime the primer as its running it will stay running for me,,,,I feel air leaking out by the primer bulb when its running.Please HELP ME????????? Thank you for your time,,,,,,,,Rick-------email me at ricksprg@yahoo.com.....I'm thinking the primer bulb has a hole or a crack in the rubber ...............
hi rick i just joined here i run into them problems alot here and what it is is the primer could be not seated correctly in the carb there is a round retainer clip that holds that primer in place if that retainer clip gets worn anyway it may encounter a leak and if there is a leak it will make the engine run rough another thing you do is if it starts and then quits take the carb off the unit and take a 1/2 wrench and undo the bolt on bowl and take that float out and shake it if you hear any kind of swish sound that means the float has a pin hole in it this is common for carb floats in tecumseh engines what causes that is the carb is set up thru winter season without being runned so all the excess fuel is working on that float the replacement float part number you look for is a # 632019 and i dont know if i can advertise my business on here or not but i will contact the admin on it and see if they can add a link to my store but i thought i thought i would help you out a little on the diagnosis problem now for the primer sometimes they can get a small air leak the primers some of them suppose to have a pin hole in the center this helps out in many ways but what i would do before doing anything with primer is check that float first thing that start and cut off symptom tells me you have a float issue and not a primer issue hope this helps you out
