Re: What Throtle bracket to use 2bl to 4bl upgrade
Thanks for the link. It looks like I can oder secondary jets from Eddlebrock. A mercruiser service bulletine I found (http://www.boatfix.com/merc/bullet/93/93_15.pdf) shows the non vortec V6 came with secondary jets "ED" stamped on them? What I can't figure out is why the rods used in the 5.0L engine using "CL" have a larger power tip (.0667) then the ED (.0567). If I am understanding this correctly the larger power tip = less fuel because it restricts the total metering area b/t the jets and the rod? What secondary rods do you recomend assuming I have the "ED" ones in there now?
If I am bogging on transition into the secondaries It's either the secondaries are opening prematurly (possibly wind up spring adjustment) or not enough fuel at the higher RPM (secondary metering rods)? It seems like changing or bending the hanger can also effect the mixture, which is probably why Carlos had me bend my hanger. Nothing I read mentioned anything about inspecting the spark plugs at diffent RPM ranges to determine tuning. I would think that this would be a good method in a boat? My thought was to put in a brand new plug, run the engine at cruise for a couple of miles then inspect? That would tell me the primary side, then I could do the same for WOT. What do you think, would this work?
I wish I would have just saved my money and purchased an Eddlebrock 1409 with the metering rod kit designed for a 4.3L vortec, oh well live and learn.
