Won't start when warm

[DonziDan16]

My dad's Donzi 18 Classic won't start back up again once it's at operating temp. Starts fine when cold. Has a brand new Edelbrock 600 carb....had the same problem with the old carb too (holley 750). Don't think flooding is an issue....doesn't seem to be dripping fue or anythingl. Ideas?

vapor lock?

Do you mean it won't turn over or that it cranks fine, but just won't fire after it is warm?

Cranks fine, no fire :frown:

Don't really think it'd be vapor lock...engine temp stays in check and the fuel line is decently far from heat sources

Check the spark from a plug-wire to ground.... (Be careful)...coil wire to ground (be careful)...

How close is your fuel filter from your manifold? I put too long of a filter on mine(warning label right in front of me) and had wicked vapor lock.

Thanks for the replies guys. Turns out the timing just needed a slight adjustment!

Dan, Glad you got it figured out. Sometimes that happens with weak coils as well.
