1988 5.0L LX tune up parts needed

[keviwe]

I have a 1988 5.0L LX serial 0C394369. I have it stored out of state so I can't check to see.
Does it have ignition points?
It's hard starting when hot so replacing:
- Distributor Cap and rotor - Is Sierra good or is genuine Mercruiser cap & rotor best?
- spark plugs (AC Delco MR44T ok?) or recommendation?

What other ignition parts do you recommend? coil? condenser (if there is one)?

I might check my carb accellerator pump because I have to open the trottle a bit to get it to start when hot

Thank you for your expert advice!!!

No, its TB4

- Distributor Cap and rotor - Is Sierra good or is genuine Mercruiser cap & rotor best?

I don't use Sierra but many others do

Correct MR43T

My guess is your carb needs a rebuild, the other ignition parts don't cause it to be hard to start unless there is other issues.

Yeah, it doesn't misfire and runs strong so I guess I'll not replace ignition parts and re-focus on carb kit. Would you know the carb brand and model so I can buy a carb kit before I head out to boat storage (which is 1200 miles away, I now live in CO, boat is in Somerset KY). Want to have all the parts before I get there so I don't burn vacation time chasing/waiting for parts. 1988 5.0L LX serial 0C394369 (4 BBL GM carb - Rochester??)
Thank YOU for your input!

Somerset, not that far away from me

If the carb is original it should use kit 823426A1 item 12

I’d be looking at the choke function.
plugs I’d use on that engine would be NGK BR6FS
