Avenger 85- Low Power

[NeedSpeed]

The head torque on mine is set to 144 inch pounds.

I also have had bad experiences with acorn nuts, those were replaced with hex nuts a while back.

Do you have methods for testing for air leaks?

Yours is running at least. I haven't been able to get mine to run at all. When I'm checking an engine that doesn't run or is not installed, I use a "Mighty Vac" or a HF brake bleed pump connected with hose to the intake. You will need to make a plate or similar way to block exhaust off. This will show how much vacuum it holds (if any). To test pressure, I adjust the output on my air compressor to where its barely pushing any air, usually 3-5 psi, then I place the hose to the intake with the exhaust still blocked off. I then spray soapy water mix EVERYWHERE. Your leak should be quite easy to spot. I plan to make a slip on intake adaptor with a schrader valve so I can better control flow and pressure. Did you find your problem?

Had a similar issue on a 2 stroke chinese scooter i had to fix. It hardly started and sometimes ran rich, sometimes it would rev on its own and after it would warm up, die like it ran out of gas. Issue was bad reeds. Changed the complete intake system except the carb and it was fixed.

Nope. I never found the problem. I ended up selling the kit and went back to a much more reliable DIY e-bike setup and couldn't be happier. So that "fixed" my problem.

What setup did you go with?

Once you mix oil to fuel that has ethanol in it, it goes stale within a month.

Do you guys not typically premix the oil and gas in the gas can? I thought that was the better route last night when I did that, but maybe not? Doubt it'll be an issue with this first fill of the can but could see not going through it in a month when it becomes less of a novelty.

ALWAYS mix the oil and gas in a gas can and then shake vigorously to mix it evetrytime before pouring into tank.

What he was talking about was when ethanol is in the gasoline your using, it degrades the gas and oil mixture faster then if it was ETHANOL-FREE gas you will be using...Many of us here use only ethanol free gasoline, (myself included), to avoid the ethanol eating out the crank seals as well as the aluminum in the carbies and fuel system.

Great info to know! Thanks for the link too.

it's probably the crank seals
