G1 won't always climb a hill

Tjsg1 · 07-25-2016, 04:51 AM

1983 G1 that I rebuilt over the winter. New crank seals, fuel pump, cylinder and piston. Ran good for 2 months. Still runs strong except it sometimes acts like it runs out of gas at the top of a particular hill at camp. I can sometimes rescue it with choke, and I might climb the hill 5 times before it does it. I changed all of the rubber fuel lines and blew out the metal line. New pulse line. Switched the fuel pump. If it stops, I just let it back down a couple of feet and turn it sideways and it will start and run again. Like 20 seconds. Fuel tank looks ok inside from what I can see, the pickup tube is open. Changed plug. Fuel filter etc. Cleaned carb. I'm at a loss and out of ideas. It pulls the hill strong 95% of the time.

Float level a hair to low?

I'm thinking that too except it is at camp and not a great place to field strip the carb. I'm debating a 20.00 carb from Amazon to see if it changes it. If I bring the cart home I don't have the hill to test it.

I bought one of those once because my throttle shaft was worn out it ran alright but had to adjust float level and ended up just using plastic bushing to replace old brass one on original carb really all you need is Phillips screw driver pliers and 12 or 14 mm wrench to get the carb and bowl off to adjust your float

You have a point. Might be worth a shot. I'm just puzzled why it suddenly started this after a couple of months. What would change the float adjustment?

One way to figure out if it's fuel or ignition related is get a spark plug tester and next time it does it throw the tester on and make sure it has spark if you want to test some things before pulling carb

the cheapo carb is a almost-perfect copy, look closely at the maker name on the carb, it will likely be slightly mis-spelled on the knock-off carb. im not a fan of the china copy carbs, but hey, if it solves a problem......

I didn't inspect the name that close. If I can see it now that it is installed I will check that out. Thanks for the information.
