Give me some guidance…

509’s, custom 235/241 hyd roller cams, single plane Merlins, 850 Demon carbs, MPI (Voyager) distributors.

Half the time, engines act like timing is way advanced, won’t start because cannot turn over. Five minutes later, no problem. Timing at idle is 22-28 degrees. Revs good. Put in gear, and stalls. Will not restart. Acts like advanced to the moon. Retard distributor, starts and sounds like a fueler with 16 degrees, won’t advance either. I’m about done with this mother f’r.

Anyone want a Formula 311 cheap??

Seriously, what’s a good, not too totally stupid expensive ignition to throw on this thing?

Excuse tone… I’m a few beers and rum punch in. ****ing boat.

What ignition do you have ?
You sure not some reversion causing startibg issues ?

Sorry. I have a dim bulb. I didn’t read half of what you wrote. Lol.

what kind (style) starters do you have ?

I’ll give you $1800.00

Shoul be a reversion issue. TRS with exit just at the transom. In the water the tilt was enough to have to adjust floats.

Really strange. Idle AFR will go from 13 and change into the 11s. This is reving then going back to idle.

Maybe carbs are junk.

Idle kicked to 1000 and they both die going into gear just trying to get back on the trailer.

Starters are brand new gear reduction.

Did this run good before and not now ?

Joking aside, why not Marine MSD? Seems they all have their problems.

I had same starting problem on a 502 after a starter it turned out to be a hidden battery cable end ,looked good outside but poor c objection inside ,also had a battery switch mess me up ,it was new!!! Good luck
