anyone have any good tips on repairing a intake manifold? or should i just trash it an get a new one? the one i have has almost came apart right by the carb, looks like the rubber is seperating from the metal body (unvulcanizing i think it what it's called lol). just looking for a temp fix to try to be able to ride it this weekend, or if theres a perm fix?

ok thanks,, also been reading about just removing the oil pump an premixing the gas instead. i might go that way, i like the idea of not damaging motor cause oil pump quit working.

i picked up a 2011 ningbo rhon scooter, or thats what the tag says it is, kinda looks like a tao tao but they all do lol. it is missing the throttle grip an housing on the handlebar for the cable. down by motor there are 2 cables, 1 coming from carb, other coming from oil pump. think i am missing the splitter box, if thats what it's called? somehow the carb an oil pump cables hook together but i dont know how. anyone have a pic of they'rs or know whats its called an where i can get one? thanks

well i fixed it,, i took carb apart again an blasted it all with cleaner an compressed air, double checked float height. checked the 2 vacum hoses which had no leaks, checked valve clearance an found exhaust was tight (bingo problem right there i am sure), got both valves adjusted. put it all back together an it fired up an runs now. now to sell it before it acts up again lol... thanks for everyones help on figuring this thing out.

ok i'll take intake manifold off an check the o-ring an surface. an yea the motor has gotten warmed up a little from all the short running it has done. but in between the running i have let the electric enrichener move back to "on" position an it'll still run the same, starts then idles an rev fine for about a minute then slowly revs down till it dies, just like the enrichener shuts off the extra fuel. also through all this the stock air box an filter have been on an hooked up just like normal, have read these are very sensitive to that. gonna try starting it again an when it starts dieing i'm gonna try covering the inlet for air box to choke off the air an see what happens, guessing it will be the same as the enrichener being "on".

yep, vent tube clear an pointed downward. there is a tube that connects to bottom of float bowl an has spring wire wrapped around it, it goes down to some metal cap thing that is attached to tranny case. i know thats the float bowl drain line but there is no screw to open to drain it on the bowl like all other carbs i have seen.

took exhaust off an still same results. took gas cap off an still same results. also took fuel line off carb an ran it into a container an turned on manual shutoff valve an it flows gas nice an smooth with cap on or off so 100% sure cap is venting an no vacum lock. motor bogs out an slowly dies either at idle or reved up, does not rev up high then die an does not just instantly shut off like turning off ignition switch. seems like once the enrichener turns off (or like it does is extend the needle into the hole to shut off excess fuel), then the motor dies. i know the jets are spotless an so are the passageways. not sure how to test if float bowl is venting so maybe thats causing the problem an once the fuel runs out or low the float dont open to let more in. i know the float an needle are not hanging up cause i checked those when i had bowl off an float an needle move freely no matter what angle i hold the carb.

ok update, got carb cleaned spotless, jets an all passages clear. fresh gas in tank, new filter an lines. still doing the same thing as before, will start an run great for about a minute then dies. unplugged the electric enrichener an it bogs out at idle but will rev up an run good but still about a minute an it dies. just like it runs the fuel out of float bowl an no more goes in, but i know float bowl is full.

oh guess i forgot to say there is a filter an a manual inline shutoff valve. new to these electric choke carbs so yea i guess after about a minute that would shut off an if jets are plugged then it would die. but i did try running it with the electric choke unplugged an it did run a little longer before dieing but it still bogged out an died. i'll take carb apart tomorrow an give it good cleaning an see if that helps any.
