Just me I would do a compression test which would confirm the long block (including t chain cam timing/head gasket sealing etc) is Ok if you get good numbers. I'll assume that the dampener ain't slipped (for now) but wouldn't hurt to confirm it with the $10 plug hole 14MM screw in tool. My 1406 600 eddy needed richer jetting from a strip kit on a DD & the elec choke came off way too fast but first what I would do on yours is block the rods up on your carb & see what being on the power circuit full time does for the driveability which might help confirm a vac leak and or lean jetting and or lean choke (easy to do/free/takes little time). EDIT & yes bump the initial up (I have 19 on a bone stock 318)
