Small Engine Problems? Ask an Engine Mechanic for Answers ASAP
Greetings, My name isXXXXX and I am here to help the best I can. My goal is 100% satisfaction. Let's get started.
if you take the spark plugs out, will it spin up fast as normal?
with plugs removed it does
the briggs adjustment is different than the kohler
do you have the model number of the kohler engine?
I can get you a complete service manual
the correct adjustment procedures are nbotmally in chapter 10
i did get that one
but sometimes in chap 9 or 11
valve clearance is the issue?
If it spins with the plugs out
and not with the plugs in
i had adjusted with the flywheel key at top
then the compression release is not activating at all
and then withe flywheel key aligned with pistons
easier than that, you probably did it wrong
with the plugs out
just spin the engine back anbd forth until the valves are at their widest gap
i had turned engine to where both valved are completely closed
on either side
and then adjusted to .005
adjust one, then make sure that yu spin it so the other one is at its widest gap
the .004 or .005
not that critcal
book may even say .004 and .007 depending on whether intake our exhaust
that had been done
but if the gap is too wide, the valve will never open prematurely at low rpm
and you WANT it to
after you get it adjusted
so that had been done
everything adjusted to .004
at it widest point
so if it still spins with the pllugs out
and wont spin with them in
there might be an obstruction that stop it form spinning
such as a large piece of carbon
or a loose screw from the carburetor
so engine will spin with plugs out past that obstruction
ONLY if the problem is too long of new spark plugs
I have seen that
Or if the screw had embedded itself in the top of the piston and was hitting the plug
but I will bet you a dollar that if you RECHECK the valves
pressure is built up inside engine while turning by hand
difficult to at two points
difficult to turn at two points
that al least ONE of them will be open wider than the .004 at its widest point
I would be worried only if the problem was the same with the plugs IN
I am saying You have this problem nailed, and don't kniow it...
Unless the muffler is 100% clogged
and there is no place for the exhaust to go
engine is difficult to turn by hand with plugs in all valved adjusted to .004
If one of my mechanics were telling me this.. I would listen, then if they argued with me
I would bark at them to CHECK IT AGAIN...
I will buonce this off my brother who has a bit more experience than I and get back to you...
two adjustment methods are there
center nut on the rocker arm
did you say you already had the SERVICE manual for the engine?
and end style adjustment
service manual is there
I want to make sure you do not have hydraulic lifters
If you had hydraukic lifters, all bets are off
There is STILL a possibility that you have a problem with the cam shaft or the ACR (automatic compression release system).
i can check acr/
model number is XXXXX
i was mentioning two menthods valve adjustment
center style adjustment and end style adjustmnet
they can be combined?
to reach .004?
Does not matter how you get there..
as long as when you are done and you spin the engine round and round that the widest gap on any valve is .004
just test after all the work is done
i can check something else?
Let me convert to Q&A
then I will contact my brother
and see what he has to say, then get back to you
