Is this bad news? Picture

[Chuckthizzle]

SO I am checkin my newly purchased blaster out and I removed the carb cleaned it and reinstalled it, I noticed black oil caked up on the exhaust manifold so I unscrewed it and yucck! There is NOO gasket here? wtf , Im pretty sure one is suppose to be here, I just ordered a engine gasket set wtf? Do people just drive this around with no gasket, and is the black oil a bad sign f things to come?

There is nothing wrong with that. Clean it up, put the gasket (metal ring) in there. Always do a the three tests. Compression test, leak test, and plug chop.

no biggie, black splooge is common
seems to be running rich ?
could just be a dirty air filter ?

that flange to cylinder does not get a "gasket" per say.
it takes a doughnut crush gasket, which may be in there ?
it sits into a groove in the cylinder.
they're relatively cheap and easily replaced.
no need for a complete gasket set

Got ya I just ordered the air filter off ebay.Uni filter. Hey do I need to remove the engine to do the leak down test? And once i get the new filter do I need to add oil to it?

 

[Chuckthizzle]

I bought a new spark plug also Do these these need to be gapped

yes oil the new filter, and remove the carb and exhaust pipe to do the leakdown test, makesure the sparkplug is in when you do it, not that I have ever done that and make sure the piston is at bdc and you only pump it to 7psi

Haha I see dont feel bad I just posted on facebook"Make sure you wear goggles to protect your eyes when cleaning your carb with carb cleaner" I was cleaning that little sucker with carb cleaner when it ricochet off a corner on the carb and hit me dead in the eye!! AHHHHH FAWK that burned!

 

[Chuckthizzle]

how do I make sure the piston is at bdc? Do you mean top dead center?

I don't think the piston has to be a top dead center. Not 100% though.

 

[89blaster89]

it has to be at bottom deadcenter! use a long stick or something down the plug hole and turn the motor over until its at bdc

 

[Chuckthizzle]

rodger, remove spark plug put long stick down tube move quad till the stck is at its lowest point

yep I:I you got it

Or you could just look through your exhaust port and ensure the piston is as far down as it can go. You never want to put anything like that inside the cylinder.

hahahahhahahaha No twigs,sticks in your cylinder!!!bad idea 89 lol Much better idea to look through exhaust port.

idk lol I have always just got a long screw driver to push the piston down to bottom dead center never thought to look up exhaust lol

 

[Blaaster]

No real drama if the piston is not at BDC or anywhere come to that.

The pressurised air will easily work its way up past the piston and rings.

The first pressurisation may drop a little but you can top it up to 7 psi.

The NGK plugs are usually pretty damn close to the correct gap. It's always a good idea to take the 10 seconds and check the gap, should be right around .8 mm !

 

[Blaaster]

0.7 - 0.8mm, 0.028 - 0.032 in.

lol u guys are too much lol BTW im looking for homemade leak testers. What size plug and where do i get them from to close exhaust and intake ports?
