Inconsistancy. If you could depend on them to be good or bad... then at least you could depend on them.

I've seen a couple of LA's that worked fine. The first LA series engine I saw at the field... I was wondering why people were complaining about them on the net... it had good power... it started right up straight from the box and was able to be adjusted for stable idle within 2 tanks of fuel. It produced the power you expected from the size engine too.

I've now seen more that had problems than ones that worked.

The one I have been fighting with the last month simply refuses to give as much power as an engine half its size. A .46 that struggles when turning a 10X4.[:'(] forget putting a 11X7 on it (which it SHOULD be able to turn...at least 11,500) I have SEEN LA.46's turn 11X7's... and do fine.

Its not lack of adjusting skills... I have been tuining model engines for 30 years. I'm very familiar with the air bleed carbs. I have cured the problems other people were having with LA engines!
