QuestionQUESTION: Eric I have a hs624k1ta snowblower from Honda, there is oil leak under gas tank coming from governor aperture, the oil is coming up through top where governor connects to arm, I looked at schematic of engine, yet there is no bushing, o ring ect ect in any diagram, what would cause the pressure to force oil from the top of that unit, I'm baffled, thank you in advance bill
ANSWER: What weight of oil are you using? SAE10-30?
Is there a crankcase vaccum leak? Sometimes the dipstick o-ring does not seal causing a loss of engine vaccum.
Do you have a vaccum gauge to check the vacuum?

QUESTION: Eric I am using 5w-30, I do not have a vacuum gauge, but the dipstick threads was stripped a bit, could it be a clogged breather tube from ohv cover, or bad ohv cover. thanks again in advance
AnswerI have read many responses about clogged breathers but have not had too many issues with breathers. However, I always clean them and make sure they are functioning so this may be a preventative measure that is actually working.
I would clean the breather and make sure it is functioning just to be safe. Several years ago Briggs had and issue with dipsticks leaking preventing the engine from maintaining a vaccum.
Goolge "small engine vaccum" for You Tube videos and you will find a few videos on checking vacuum.
Let me know if you find a vaccum problem.
FYI, you should not have any issues using SAE5-30W oil...this is the most common recommend oil weight for 4 cycle snowblowers.
