Default RE: Quadra 52 won't run under 3500 HELP

Some where between the carb and the engine. I'd look right under the carb to make sure there's no leak there. I don't remember what a Q35 looks like, I got 75s and 100s the carb sits on the side and inducts into the crankcase with reed valves under the carb. If the Q35 is like that that's where I'd check first.

Also check that the crankcase seals are good, if they leak or the bearing seals leak it'll give you the same problem.
