Slow or no-start Briggs Intek with good valves? Starter struggling at the same point? Tada!

[@ThePower1037]

That has to be the laziest way to make the starter smaller, they could've at least made the "lobe" rounder.

[@kurtknispel9170]

I watched your video and had a motor with the same issue. Put a used cam out of another motor in. I see the slight bump of the compression release but it doesn't seem like enough. Valves set at .005. Do these wear out? Still getting stuck on compression stroke

[@MechaniChics]

If you see the slight bump, that's enough. Depending on your model, intake should be set .005-.009 and exhaust set at .003-.007. If this was a problem for a while, it could be that you strained your starter. Does it turn over fine with the plug out?

[@kurtknispel9170]

@@MechaniChics yes. I'm running a jump pack directly to the starter. I'll mess with it some more today. Not a fan of these motors. Seems like they blow head gaskets, leaky valve cover, broken compression release on cam, and wear counter weights.

@@kurtknispel9170 Good luck. I replaced one this week that had broken one rocker arm and bent the other push rod because of the ACR. The valves were set right but the intake rod was so bent it wasn't opening the valve correctly. New head for that one, too. Check that today and let me know.

@@MechaniChics well pulled the push rod for the intake out. Looked straight till I rolled it on a slab of marble I use to surface heads. Very slightly bent. Replaced that and it's running great. Thanks for the help. This is the 1st one I've fixed. Usually I have plenty of good used motors and just replace. I've ran out of good used ohv briggs so I'm trying to repair some since we're getting into the off season. I've got several that have the counter weight knock I'll be doing next. This was the only one with the compression release issue and I got it with some free mowers a few days ago. Keep up the great videos. I've been having another issue with a troy bilt bronco I can't seem to solve. When I got it the drive belt tensioners were off. Put some on and it wouldn't go over 2mph even after adjusting tension. I've tried other belts some it wouldn't drive others went 5mph but was too thick and binding on tensioners. Some of the belts ended up working just fine on other machines with similar drive system difference being drive pedal and brake on opposite side on problem machine and same side on other machines calling for same drive belt. I've tried other pulleys on the back where both belts go. No change. Rolls good. I'm lost on why this one won't do right

@@kurtknispel9170 I posted a video on the variable speed pulley last year, but you're saying this one has a single drive belt with pulleys and tensioners operated by the brake pedal and not a VSP? If so, can you see if the belt is slipping or if the transmission just isn't turning quickly? You checked the model number and belt specs to be sure the belt you're trying is exactly what is required? Those OEM belts can be a third of an inch different than the aftermarket and make all the difference. Hydrostatic transmission? I guess you could just send me the model number so I could look.
