hf blue engine

[rockstomper]

Hey everyone been while any way wondering if any one can tell me what the valve adjustment is cold on the hf blue engine???

My son (12) did some work on the cart before we moved and had lost the 1 of the screws that hold plastic part on the air cleaner to the carb...Well I found out were it went.........Down into the engine did not run when we got to the new house.

It was a mystery it just would not start,Asked my son what he did and he said don't know so I check it and no compression so I pulled the rocker cover and the intake was a little short of a full close pulled the head and found it.No bent push rod or valve so were good to go just need the adjustment specs!!

Cold
intake 0.15 ± 0.02 mm.
exhaust 0.20 ± 0.02 mm.

Cold
intake 0.15 ± 0.02 mm.
exhaust 0.20 ± 0.02 mm.

Are you sure about that? Seems kinda wide.

Ho-hum...

Are you sure about that? Seems kinda wide.

Swear by the hair on my chinny chin chin. As usual, I can back it up if needed.
Right Mr. Kibble?

I request backup, not saying your lieing but my research shows that .002in and .003 ex is what the modded clones run, cant find the Honda specs(but im not looking hard at all). It appears honda wants me to buy a manual and wont give me a torque and clearance spec chart like briggs will.

The 17hp OHV briggs I just put a had gasket on calls for something like 3-5 thou on the intake and 5-7 on the exhaust.

I don't even bother to argue on this one. I have no idea what it's supposed to be.

Okay so Honda calls for wide lash. But why?

I am with Kenny too .002 on intake and .003 exaust is what I hear of too. But I trust russ as well.

 

[Russ2251]

All 3 genuine GX Honda blocks have same specs.

 

[rockstomper]

Thanks Russ, It runs great!!No other damage done! Got lucky on this one.
The spec you gave me worked fine.

Thanks Rockstomper

Article in question specifies inch, not mm.

 

[Kenny_McCormic]

SMACKS HEAD ON KEYBOARD!!!
I though first # was inch, I suck at paying attention.

That roughly translates to
in 0.006"-0.001"
ex 0.008"-0.001"

 

[Russ2251]

Your welcome. Sarcasm NOT intended!!! Well...maybe it was.

I was wondering why you guys were arguing.... I was like: "I hope they're not confusing the measurement units..."

 

[Kenny_McCormic]

Why do we have to be different?
