View attachment 27658OK new rave valves ,housing s ,pistons gaskets orings. Big difference!Pulls really strong .first day would pull good and hard right up to 7200 rpm and stay there. Now on day three still pulls strong but I only see 6500rpm. Gradually rpm started to taper off. Drained oil and am running full syn xps. So I took apart raves everything looks good. Did a hispeed spark plug run maybe a little lean on PTO so I'll back out hs adjuster. Next week I'll verify compression. Was 150+ at start of season. Too bad it ran better then ever after rave housing swap. But we still had a great weekend. Does any body now of a good method to verify flow of fuel pump .
