I was given a Troy Bilt a couple of weeks ago because it "wouldn't
build pressure" and I think I figured out why . There is a ball check
vent valve on the HP outlet . The spring holds the ball off the seat
under normal hose pressure but as soon as the pump builds pressure the
ball is supposed to seal the outlet . Except the ball and spring are
missing ... Soooooo , the question is , if I can't find the ball and
spring can I just plug the hole ? I think the only difference it will
make is that I'll have to hold the wand trigger down while starting the
unit . I just replaced the bypass valve because it had a crack on the
piston head . I think the missing ball and spring are venting enough
pressure that the bypass valve never opens . I'd like to get this unit running , it has higher pressure and flow rate than the last one I got
for free .
Yes , it vents to air . Near as I can tell it's purpose is to vent
pressure as the motor comes up to speed . My other gas powered washer
doesn't have that feature and you must hold the wand trigger down to
start it . I'm pretty sure plugging the hole will result in having to
hold the trigger down to start this one too .

A bit confused here; does the missing ball check valve vent to air?
FWIW there's a Youtube channel called "Mustie1" with at least a few
pressure washer salvage videos, along with many more.

Replace the spring and ball with a manual valve - open to start,

I haven't watched any videos , but I did download the repair manual
and the parts diagram . The diagram shows a ball and spring under the
vent nipple , it's missing on this unit . Inspecting the nipple shows a >bright ring where that ball has seated on a machined shoulder . I can
think of no reason to have this feature but to relieve pressure at
startup . The nipple will be going to town with me this morning to see
if I can find suitable replacements . If I can't , I'll plug the hole
and see what happens . And if I can't get this thing to run , I'm only
out about 25 bucks for parts and I'll have a 6.5 Hp B&S OHV motor that
can be used for other things .

Well 10.5:1 ain't all that high and it's not a big inch motor so ...
but I did install some compression releases for a big inch S&S motor for Buttplug Smith one time .

I think my Cow is 10.5:1 and the darn thing requires high octane fuel in order to eliminate ping.
