The Viper Engine is a Honda clone. Try a new carb for $15 0n ebay. http://www.ebay.com/itm/NEW-GX160-5-5HP-HONDA-ADJUSTABLE-CARBURETOR-WITH-FREE-GASKETS/121225345625?_trksid=p2047675.c100011.m1850&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D30002%26meid%3Df495007fc18649159ceb1009031e4fad%26pid%3D100011%26rk%3D2%26rkt%3D10%26mehot%3Dpp%26sd%3D261393057447
The problems you describe are usually indicative of a blockage in the fuel system somewhere in the carburator or a damaged gasket that's letting in too much air. With the choke on, the vacuum in the carb goes way up and forces more gas through. Remove the carb and check the gaskets and insulator if it has one. Then check the float bowl for debris and blow out all the passages in the carb.
This truck is fuel injected, the problem sounds like a weak fuelpump, it runs when you pour gas into it until that gas runs out, the first thing is to test the fuel preasure, if the pump is weak it may run with gas poured into it but wont idle, also a common problem is the coolant temp sensor and the ground wires to thermostat housing bolt but i wont bet its the pump inside the fuel tank, if you put a fuel gauge on it there should be at least 55-61 psi if its a few pounds lower it can cause problems, you have everything else and it runs with gas poured so its a fuel problem check the preasure, theres a valve up top on the fuel line to connect a fuel gauge to it, start there hope this is helpful.
If it's been sitting for 3 years most likely the carb is gummed up. If it's getting spark, you could try a small shot of starting fluid into the carb. If it runs on this you know it's a fuel problem. Best bet would get all the MOTOR data, and buy a carb kit from you local lawn and garden equipment parts supplier. . Remove carburator and clean and install kit. Use sta-bil when you put it away next time, but even that only works about a year or so.
Sounds like fuel starvation. there is a small filter insde the tank. if you take the tank off you will see that where the fuel hose attaches to the tank. this spigot unscrews from the take to reveil the filter.
Hope This helps
Two things here, Pull the line on the fuel tank off replace the in line fuel filter and replace the gas pump bulb if it is bad it will not allow the gas to stay in the carburetor. Also pull plug and see if it has good compression by putting you finger on top of it and move the flywheel till you get compression. Also the governor may be sticking it's connected to the carburetor and the arm that goes inside the engine. But the filter first.
If you have a primer bulb and the motor "recovers" after a near stall with a pump of the bulb, then you have to replace your fuel pump. Johnsons do have this problem often. Otherwise it could be the high speed jets although it sounds like you checked the carb good. Also if you have a primer bulb, Replace everything from the tank to the engine. Costs about $14 at Wal Mart, $55 at a boat place.
Try starting the washer up without a nozzle clicked in and purging water through the pump, shut it down and install the nozzle and restart, if the motor lugs then it is making pressure, if the pump squirts water out of the by-pass immediately and or constantly it may be a stuck bypass and not a bad pump.
