I have five DLE engines and always use the spring. I've flown thousands of flights and never had a problem with them. When the 120 degree caps first came out they were hard for people to get on and I...

Al is correct about the ignition having problems on the compression stroke.

Back in the old, old days, when we fixed everything instead of throwing it away, we used to have a spark plug tester. It...

I'm not talking about using the choke at all, just squirting a few drops of fuel directly into the air inlet on the carb. It should run for a few seconds at least. If it will run that way, that...

I know you say it won't run, but that can mean a couple of things, like not at all, or for only a few seconds.

Will it run for a few seconds if you squirt a couple of drops directly into the carb...

Everything left is outside the engine, muffler, fuel tank, fuel, prop, prop nut, etc. I can't wait to see what the root cause is.

It seems like if you've replaced the carb, cylinder head, piston, ring, crankcase, spark plug, ignition, hall sensor, and reed valve, that you are not even working on the same engine that you started...

I don't think that is the problem. He's had the engine a long time and it was working okay, then it quit. He replaced the carb. It would be a rare event if both carbs had a bad pivot arm.

There are two things you may try.

Red Rider was doing some repairs, but I haven't heard from him for quite a while. I don't think he could get parts either.
