Old gas?
Try a new glow plug?

needs a new piston and sleeve....once it heats up you have no compression

 

[Ballen]

brand new gas , brand new plug, engine doesn't have 1 1/2 gallons through it . and does have good compression . even after it starts to bog If it stalls it still has good compression on the restart.(doesn't stall unless i give to much gas starting from slow roll or stop ) if i ease it it goes fine and has great top end

is the engine sealed?

 

[Ballen]

no , was sitting for around 1-2 yrs ,not gummed up or burnt piston top is nice and clean .
was thinking maybe tune lsn maybe just didn't adjust enough,now i live about 60 miles from the ocean befor was probably about 400 - 600 ft above sea level.i know it needs to be adjusted because of that but don't know which way.

 

[bgbdwlf2500]

seal it first, go back to factory settings all the way around.

2nd post in this thread should help..it works well.
