Hello. I have a 1986 gxl that I just rebuilt the motor and converted it to carbureted. I have all my msd hooked up. I have fuel and spark to all plugs. The problem is that the motor cranks and it doesn't fire up. I need help

 

are you getting any hints that it's "trying" to fire at all?

if you have confirmed fuel, spark and all coil and plug wires are correctly placed, then move along to checking the timing.

 

It sounds like it wants to fire. So far I'm thinking its a timing issue but I have everything set up like my first gen because it has the same set um but still no luck

 

well, you may be a tooth off. put a light on it and see where you are.

 

Thanks. I'll try it out. Is there also a chance that the engine is flooding?

 

possible? yes.

you can pull the plugs and check them. you can also disable the fuel pump and try starting it. what carburetor and fuel pump?

 

I have a weber 48 Ida on as we'll as a Holley red fuel pump with 1-4 psi fuel pressure regulator

 

was your Gen I a 12A or an SE?

 

12a

 

well, I would kind of doubt a flooding condition now. obviously I cannot confirm this, but i'll put it out there for a future time just in case. your jetting may be off. when I had my Dell'Orto, the jetting made a night and day difference in how the car started, idled and performed.

put the light on it and confirm your timing. if it's off, get it sorted. then try seeing if you can get it to fire on some starting fluid or carb cleaner. if it does fire, then start the re-jetting process.

 

I have the distributor set to the leading mark and to leading number 1. When cranking, the timing light shows up on trailing

 

have you checked and double checked the coil and plug wires?

 

Yes I did

 

The car backfired though the exhaust while I was cranking it

 

are you moving the distributor between cranking? may be retarded a bit???

also, are you pumping the accelerator before (or during) cranking?

 

I wasn't moving the distributor but I was opening the throttle a little bit
