Still have not got my HAPI engine with a POSA throttle body and Slick 4216 magneto started.
These are the facts as I have them right now. 1. Compression of the cylinders indicates that the engine is good. a. FL 125 b. RL 110 c. FR 125 d. RR 115 2. Spark is interesting. a. When hand propping I have a strong Spark in the front cylinders (FL & FR). However the rear cylinders (RL & RR) do not produce spark. When spark plugs are swapped no change, the spark plugs do work. b. When I crank the engine, the spark in the front is strong (FL & FR). But the rear cylinders in this case (RL & RR) do produce a weak spark. c. My question is should I be concerned with the harness or Magneto? 3. Fuel: I've changed my fuel plunger and can now pump fuel into the intake manifold. So, I should be getting fuel. Only concern is that I may be flooding it. a. I also bypassed the fuel check valve right now. So, the POSA should be getting fuel. 4. POSA – checked the POSA needle orientation. It is in the correct direction with the round side facing front. Any insights. Dee
