I was running today around 4100-4150 rpms and the engine made a pop noise but didn't lose any power. I stopped to see and in neutral it seemed like it had a different kind of vibration. Any ideas?

Well according to Robin, if it would be a GoDevil you could rule out the clutch and the transmission. ;)

I don't think it was a clutch or transmission. Nothing's slipped

^^^ I was thinking push rods also

You would lose power if you threw a pushrod though. Right?

^^^FAIL!!!^^^ Talkin push rods, not connecting rods :roll:

Yeah, Owen, it would run like shit if he threw a push rod. I missed where he said he didn't lose power, was focused on the vibration.

Could it have been a backfire and you just noticed more vibration because you were paying closer attention to it?

Is the motor stock?

Plugs may be in the beginning stage of fouling, pull them and check em. Last time mine popped i had to limp on one cylinder to a hunting hole, come to find out i blew a head gasket. Not your problem cause you would have noticed that.

Post subject:  Re: 35hp problem

You mean helpful like suggesting push rods without any power loss? Or maybe a blown head gasket that obviously isn't the problem either?

I'll keep that in mind.

Just carb and exhaust

Does it idle smooth still? If the idle is rough now, check your intake gasket. It could have ripped and now causing an air leak.

Might be the baffled in your muffler came loose better check fast them fuckirs will be on top your piston in no time

Post subject:  Re: 35hp problem

Do you have a rev box on it? Could've just been a hiccup in the box, causing a backfire like was mentioned earlier.

Author:  jakecologne [ Sun Jun 10, 2012 9:34 am ]
Post subject:  35hp problem

No rev limiter. And it does idle smooth. I think im gonna pull the valve covers off and take a look at the rocker arms

Author:  jakecologne [ Sun Jun 10, 2012 9:48 am ]
Post subject:  35hp problem

I have one roller rocker loose on each side...is that normal?

Post subject:  Re: 35hp problem

It depends where the pistons are at. Do you know how to set your valves?

Author:  Will [ Sun Jun 10, 2012 9:52 am ]
Post subject:  Re: 35hp problem

Yes they will be loose when that particular valve is in its seat.

Author:  jakecologne [ Sun Jun 10, 2012 9:54 am ]
Post subject:  35hp problem

No I don't know how to set them..

No better time to learn! Take your time, make sure you get it right.

Think I found my problem

Post subject:  Re: 35hp problem

yup

If you took those three long bolt couplings out and left them out, would it hurt anything?

Author:  jakecologne [ Wed Jun 13, 2012 1:48 pm ]
Post subject:  35hp problem

How does that happen? Lol. Should I stress about finding the rod that broke off. Could this possibly be the reason I saw sparks as well?

That metal screen was takin off when I had work done to the engine. Could this have possibly been the reason I saw the sparks out of the side?

Yeah and it sparked for a little while then made a noise like it threw something around in there then it never sparked again. I have the fan cover with my oil cooler on it I just don't have that other little cover inside the fan cover
