Motorcycles, Snowmobiles, Go-Carts, ATV's and Golf Carts - Hey engine kinda problem

Hey ok im building a 1 seat go-kart whit a lawn mower motor im not sure what brand its but everything is working good the spark is there the motor turns well, oil is good, but there is no gas going into the combustion chamber i found that well i was working on it, i shoved my small finger in the exaust hole and its was dry and in the spark plug hole too, when the engine turns i can here it, no gas is geting in whats the problem? do you think its the carburater or the lines, the trotle or some thing like that i what to boost the motor too so give me advise or if you have an idea of why in hell there is no gas going into te chamber let me know. Cya dudes! tnx !

Start by giving the carb. a good cleaning.

yep i did that this evening it was verry dirty now its shiny clean i put it on back and hooked up every thing and tryed it again but da hell still nothing the carb leeked i think there is a hole in it is that suposed to be like that? when i choke it it leeks and in the pipe going into the combustion chamber there is no sing of gas that whent into it it DRY but sooooo DRY lol do you think i need a new carb?

The carb can leak if dirty or assembled wrong. Did you disassemble the carb and clean the internal parts or did you just wash the outside?

i washed the inside,but theres a hole in the botom of the kinda cap can i just weld the hole?

Make sure that gas is getting to the carb. The hole you describe in the bottom of what I think is the float bowl should have gas in it. Is there gas flowing from the hole you descibe? An engine has to have compression to "pull" the fuel from the carb into the engine. Can yuo do a compression check with a compression guage? Another "cheap" way to check compression is if you put your finger over the spark plug hole while you turn the engine over. You should hear air escaping, trying to blow your finger off the hole if the compression is good. Let us know what you find.

yep there is pressure ... but the carb leeks wen i chok it and wen i try to crank the moter...

Sounds like the fuel is getting to the carb. Is the fuel coming out of the float bowl screw hole as you mentioned? Now we need to find out why it's not getting into the cylinder. You would need to check each fuel jet in the carb and make sure ther are no restrictions. Make sure the carb float is not sticking allowing the carb to overflow into the engine or air box. Do we have spark at the spark plug? (do not place the spark plug near the plug hole while checking for spark :eek: )

haha that would be something i got to see some time, well the kinda ring is floting and the pin atach to it is good i arenged everything but now all i got to do is get a new screw that srews in the midle of the carb because i twist or some thing like that now all i know is that it just wont go back in so #1 get new srew #2 atach every ting #3 crank #4 post news on this site :D

A few years ago this entry level tech placed the spark plug right by the hole and hit the starter...........1) I never seen a grown man soil himself so fast.2) the sound when that spark ignited left ringing in my ears and 3) the light show was very quick and fantastic. -Sean

you need to get the carburstor to stop leaking before it is going to work. its running by compression and it needs to be a sealed unit in order for it to work, weld it or you can just go ahead and replace it
