Hey all Im in a pickle this time. I have a G-1 Yamaha single two stroke. I have been looking for specs for this machine. Comp.? Im getting NO fuel in engine. Carb full. Barely runs with some Starting fluid shot in Cyl. All been taken off cleaned and reinstalled or replaced.. Has 110 # comp.Plenty of spark.I can pull fuel line to carb and fuel comes out as I crank it over. Give me a hint. I am very mechcnican but Im on the stump this time.

110 compression aint great, but should still run. Stop running it on starting fluid, its washing the oil out, not gonna help your compression. Sounds like the carb needs fully cleaned.

CG : As I stated that has been done. Sonic clean. Just looked at reed and they are all closed against the rubber seal.Now my fuel pump is only pumping about 1/2" out of hose when cranking.I read somewhere here that this other members is pumping 2/3"? What is about right? Even if I do shoot some fluid in her just barely a rumble. Yes I Oil in cyl. before and after. Ive been a mechanic for over 50+ yrs. But this is STUMPING myself.Ive been looking for manual for this Box and Find nothing listed.Help there? Need help as grand kids are coming this weekend.. Ya get the idea?
Thanks for any help or options,

Have you changed your crank seals? You need crankcase pressure to drive the fuel pump and help suck the gas oil mixture thru the reeds/cylinder and piston ports.

If fuel in bowl/coming out of fuel line. Plus, runs when a external fuel source is added, i am still looking in carb area. It does run off ether? and fuel does come out of fuel line (just a little is normal)?
