Specs: 460BBF, Weiand T/R, 2x600CFM Holley, Accell Dual-Points Dizzy, MSD-6ALN, MSD High Vibration Coil, Points Triggered

having a weird issue after i pulled the top plenum off to test fit a msd dizzy (should have known right there it wasnt gonna fit..)

anyways, boat starts right up - but idles @ 2000 rpm's. i taped the rotor so it wouldnt move, and marked the dizzy position before i pulled it out. stuck it right back where it was..
replaced the gaskets between the base and the T/R when i pulled it, also applied some RTV for safety.

probabaly first bet is to check my base timing, but i don't have a pointer on the damn thing - anyone know of any easy way to mount a pointer to a harman marine timing cover?

Find any bolt and use a bent up coat hanger. Find TDC on #1 then bend the hanger to indicate 0. Doesn't have to be fancy.

I wouldn't leave it on there when you're done, lol.

Lol.
Ray - you ever make it down to the Gilbert - Higley / Riggs area? I'd like to have someone else check over my setup and make sure im not missing anything.

First things first tho Nathan. Finding TDC on a 460 ford, and actually finding 10* BTDC is pretty easy, and more important. Rotate the engine so you KNOW you're coming up on compression stroke on #1. When #1 is at TDC, mark the dampner, start watching #6, a coat hanger works for this as well. As soon as #6 starts to go down, mark your dampner again, that is 10* BTDC within a degree or two. Put the dizzy in pointing the rotor right at #1 and you can't go wrong.

Boat will fire and idle every time using that. (I've never had a timing light on the Moo, just a seat of the pants adjustment from those settings.)

Your boat sounds like it fired again and ran OK, so sounds to me like you may have aquired a throttle linkage bind or your throttle cable isn't installed as it originally was. Just thinking.

Edit, shoulda noted, rotate the engine backwards from running, so it's tighteneing the crank bolt!  All this relates tio that!

I'll check the timing when i get home

regarding carb/throttle linkage, there is none, the throttle cable was shot so i removed it, and this was happening before i installed my linkage for the carbs..

vac leak was my idea, but im certain theres not one now.

Thanks Dave for bumping this, kinda. Had it in my lil brain to add to the advice, but forgot.

I too am running a Weiand tunnel, and honestly, the only digital dizzy I'm aware of that'll work and fit is a Unilite. (Not a comp 9000 tho, lol). I just picked up a dual point Mallory unit that will need the conversion put in it, but it'll clear the tunnel. (Speaking of which, I still owe Chromey for that thing, just remembered).

My stuff is all Mallory, not MSD, so maybe I'm ahead of the game?

Ray

Also reminds me to call Marc about getting the conversion kit for it! Gawd it's been hectic this week!

Well, I'm working all this weekend, off Monday afternoon though going to look at a Biesemeyer mini day in Tucson.  Wednesday afternoon I got nothing going on though.

Ray

its probabaly something dumb

It quite often is! lol

Kinda reminds me of last night! My motor has given me hell lately! Took it to hdriders again and got to the bottom of some it! We decided to launch yesterday afternoon and I still was having an issue at 3500 rpm I could hear popping and what not couldn't for the life of me figure it out...my buddy asked are all the vacuum ports pluged on the carb...I said I think so...hopped back there and had a look see...sure as shit one of the ports didn't have a plug on it! Luckily I had an extra put it on and it ran great! So I guess the moral of this is vacuum leak? Maybe put a guage on it and see what it reads hell idk...
