18hp I/C Briggs running on full choke only & what I did to fix it.
Thanks! Share it with your friends!
Mine did that too. Mine is just like that, except I used Seafoam and that seemed to work.
I put a new carburetor and the the tractor won't run it starts up but won't idle up barely runs its building up a lot of carbon I have tried everything do you think its a head gasket or a camshaft I have good spark new carburetor new fuel solenoid adjusted the valves I need help or any ideas you might have thanks for your time it's a 17.5hp engine models 31c707 briggs stratton engine
Cool I love the old Flathead Engine I have this one! Is yours 16 or 18 Horsepower? thanks
retorque the head bolts, apparently just enough to get the gasket to stop leaking. good idea. mine don't leak but at 12 years old I should check those bolts while its apart
Happy to find this older video. My old Briggs just did the same thing. I did a full fuel system cleanup at the end of last summer and it ran fine but wanted a little choke to develop full power. The third time I ran it this spring it did exactly what E-dawg's engine did. I removed and inspected the carb and all seems in order.
I'm going to check head gaskets tomorrow.
can an opposing twin be converted to gravity feed?
seeing as the breather is hooked up to the carb you would think the fuel pump is on it`s way out or new hose and clamps but the piston compression being part of the blow by makes a lot of sense good job if my new pump kit don`t work I'm going to check the heads before hand now thx!!
I have an 18.5 B&S IC model 42A707 that looks just like yours. The same thing happened to me today. I'm going to check the head bolts but don't have a manual. What are the torque specs for the head bolts?
I had the same problem it only runs on choke and I put new gaskets on the carb and the fuel pump its still Will only run on choke what should I do ???
I have one that has a problem with the silinoid, its 13 on a tag along with a 6 foot cut., now after a couple years not being run its out covered up and doing nothing. I also have a Cub Cadet 18 hore hydrostatic and it quit a long time ago.. when I removed the brather I could see 1 butterfly was stuck in the carb barrel 2 screws had fallen into the boreand didn't do much but I think if I ever get into it I might find my screws burnt to a cripst.
it happened to me once before, I took it into the shop he said he couldnt fix the carb for some reason so I had to put a new carb on and it ran great for 5 years and now, the same thing….so in my case, It wasn`t the head gasket..a comment here said sucking too much air hmmm maby a gasket in the carb….more research thanks for video
Sucking to much air the average Joe Blow would have threw it away I'm glad you fixed it too many wasteful people in this world
