Fuel problem

[Wreckingball]

Hey guys ,

I need some advice, my Terra jet has clean carb new plug new gas line but won't stay primed or continue to run , not sure what else I need to check . Any and all help wanted

Need more info, ie engine, fuel pump, etc..

It has a tecumseh oh160, no fuel pump , carbureted and about a 8 foot gas line from tank to carb

Well I believe it needs a fuel pump as the carb is probably tank level with an oh160 maybe higher. Some oh160s had a pump on the carb about the size of a small stick match box (nla), if not I'd get a mikuni style pump which will need a pulse line, the pulse line was generally located about halfway up the block where a plug may be.
OH160s also had 2 types of main jets, a bolt style plug holding the bowl on or an adjustable jet holding the bowl on, if adjustable try it at about 1-1/2 turns first and the you can go out if need be. The adjustable needle controlled how much fuel was allowed to flow through the jet with too much resulting an the black/rich mixture. The other higher mounted needle is the idle jet.

Try jacking up the front of the machine about 1-2' and IN Nuetral or with the belt off, if the machine will stay running at throttle I'd say needs a fuel pump as 8 feet of fuel line is a ways which would need a good gravity feed. Or if you have a mower or sled with a fuel pump try borrowing it, remember to hook up a pulse line which I believe is a 1/8npt hose barb.

I don't seem to have that on the motor so i ordered one I'll try jacking up the front to see if anything changes

You can also try using a baby bottle with gas in it, that will allow you to prime the carb. Once primed, these things tend to run. I added an old boat sqeeze type pump off a marine fuel tank to an Attex I had a few years back and that set up never failed me.
