4 stroke choke problems

[HeadSmess]

i cant see any nits being picked. $70, and its still a coughin? pffft.

over here we have something about consumer rights. you require either the service to be worth the price charged or at least a refund if the service is in some way faulty...


oh. i see its a gx35. diaphgram carb.

once again, you tear em down and blow em out em and they run fine again. dont touch the needles in the barrel unless you know exactly what your doing! really you should only need to undo the four screws at the base, carefully split all the sections, very carefully... watch the diaphgrams dont stick and tear, take note of any springs and which way is up! and give it a good wash in methylated spirits to soak away any water, then petrol/kero. check diaphgrams against a light for holes.

but for this lil issue, im inclined to suspect pump issues. anything thing from the primer bulb deteriated, to a bit of gunk in the filter, to a drop of water.

it really should take you ten minutes once you have the carb off!


octane boosters dont do anything unless the motors worked enough to require them

fuel cleaner may work on multi cylinder car engines with a few shellac deposits due to age, but wont do much if you got a lump of bark stuck in the needle valve!

Have the same prob on this new build today, checking easy stuff first and it's out for a test run but if it's not perfect I pull the carb and use air to clean the jets.

Thanks for the tip as despite 7 or so HS 49 builds this is the first one with this problem.

Found the prob on HS carb, just blew out the idle jet and she ran great up until it started leaking fuel. I've build half a dozen or HS/4G kits and never had a single problem but this one has a time consuming nightmare.

The carbs are only $28 at gasbike so I figured I'd just expedite a replacement so I can deliver this new build and they are out of stock!
I e-mailed them but I know how that goes, anyone know where I can score a replacement carb ASAP?

Just a note on gasbike and the HS 49cc carb problem, they are shipping me a free replacement before this bad one even gets back, that was friendly of them.

And the hits just keep on coming. Rode to work and back yesterday (because I have no other way of getting there) bike started sparaticly then about 200 yards into my ride started running perfectly, still a bit of spluttering, but plenty of power almost got up to 30 going down a slight grade. are all my problems solved or have a caused more? Thanks for all the advice, just wondering if you guys are talking about a can of compressed air to blow out the carb or if I need a compressor?

If your like me and don't have a compressor a can of air for dusting computers works well. KC I've been jacking with a HS carb on my Honda with an idle issue, found that its important to have both O-rings on the black plastic idle jet sealing properly and the jet clean. The top o-ring was letting air suck in and it wouldn't purr at all. Changed that o-ring and it idled/purred right away.

Yep, it don't matter what carb it is, all the parts in it need to fit right and play nice together or ya feel it.
