I always check the pivot studs too, they can loosen up and really cause problems with the valve adjustment, or ejecting the pushrod and giving you a dead cylinder.
I have repaired three Briggs single cyl that the pivot stud on the intake had come loose and off course the engine wouldn’t run past idle. Upon removing both studs the exhaust had a sealant, locktight, and the intake had none. Cleaned and used locktight on the reassembly of the studs and have not had any issues as of two years ago.
@@hester781 I’m thinking that the assembly trays of the two different valves may of had an application inconstancy as the trays come with sealant already on them. Or maybe the engineering thought the intake didn’t need any as the valve doesn’t experience the extreme expansion and contraction that the exhaust does.
The decompression valve does not come in to play when you’re doing a valve adjustment in this fashion. The whole theory behind it is if one valve is open the other valve isn’t being affected at all by the camshaft👍🏻
I'm a newb, but I need to check this issue on my own engine. I was wondering how you were turning the engine over? I've seen others take the fan cover off. Thanks!
I can't remember on this one if the cover has to come off or not but you are correct I was turning the flywheel by hand. However with both spark plugs out it would be just as easy to reach underneath and turn the crankshaft as well 👍🏻
@@hester781 Thanks, will see if I can do this on my own set-up without having to remove all my covers and air intake. My engine is in the tub of Max 2 6 wheeler
You got something against English Hester? Ah ha, nice video bud keep up the good work, my engine seems to be English or 3/8", 7/16, 1/2", 0.005" gap. It's a Briggs! Cheers. U.S.A.
Hey Hester great video - what was that little black hose called at the end of the video (that gets cracks and affects fuel pressure)? I've been fiddling with that thing for 3 years to get my lawn tractor to run properly (Intek xrd 724cc 23 hp) I don't know how to order one.
So there are a few different styles of these fuel pump vacuum hoses. Here’s a link to an example of one, luckily amazon has all of them. Hope this helps 👍🏻 Welironly OEM Briggs Fuel Pump Vacuum Hose Part# 793147 ;from#killian3790; TRYK8291759296696 a.co/d/4khVcA1
You are correct! I realized this after editing and someone else pointed it out in the comments. Although I’m actually pretty surprised you’re only the second person to catch my mistake! Good eyes 👍🏻
