It runs very well. I'm usually only using about half throttle when it seizes. And I'm usually in the air about 15 min. The plug looks good. I don't have any guages on it so I can't measure exhaust or cylinder head temp.

I have checked the pulse line and replaced it....I've looked at others and the fuel line is supposed to run with that loop there so I don't really want to change that. When I used the gas tank on the ground to see if it was a fuel line problem I had to use the electric start and carb to get the gas all the way up to the carb and it did it just fine..So I assume the pump is okay. I think I'm going to bight the bullet and buy another carb. With my luck with working on engines lately it probably won't fix the problem though.

Sorry to not get back with you guys. I'm almost positive the engine itself is fine....my fuel line goes to the top of the carb and then makes a loop ino the carb.....I have a 3-4 in. spot with no fuel in it all the time when it starts to make the loop...then about 2 in. of fuel sitting in the line before it goes into the carb....Now when I run the motor and hit the throttle that 2 inch of fuel goes to about nothing until i back off the throttle...I even ran a different fuel line into a gas can. Its not getting any air from the fuel line...So where is this air coming from?Back from the carb?..Why won't the line fill totally with gas? I've tried getting rid of the loop in the fuel line and still the same thing. Could the fuel pump not be pulling enough and always causing it to be lean?..The is boggling my mind. I wish i had another carb to see if that is the problem. I've had another person go through the carb as well though.

Have not done the pop off pressure. I remember reading about it somewhere but you had to have a certain guage if i remember right? The color of the plug always looked good. Have not changed the prop. I changed out the piston and cylinder twice . I put pressure to the case and it held air so I'm pretty sure its none of the seals there anyways. I gave up and gave it to somebody else to rebuild He changed all of the fuel lines and rebuilt the carb...I'm just worried that it will happen again cost even more money. I just taught myself to fly and each time ended with an engine out so its getting frustrating. Thanks for the tips just wanted to see if there was just something weird out there that I am missing.

My solo 210 has seized 3 times now and I can't figure out why...Walbro carb that has been rebuilt, all new fuel lines, have done a leak down test, ....My main question is that i have a group of small bubbles that sit at the top of the fuel line before it goes into the carb while it is running. Sometimes the bubbles are there and sometimes they are not.Sometimes they move into the carb. But I don't see where it would be getting the air from? I've stuck a fuel line in another tank to try that and they are still there. Any ideas? Thanks
