Hard starting model A

[manitobafarmer12]

Got a 1948 model a with electric start seems to be very hard starting and takes alot of cranking to even get a fire. Put in new ngk plugs and gapped them at .30 has spark but very interment what's a good place to set points?

If you have a mag .015, distributor is .021

When I start my 1950 A, I start with full choke and open it as I am cranking.
It normally starts within a revolution or two.

If you need help with a magneto, I do them as a hobby. Let me know. Thanks.

This one I can pretty much kill the battery before it'll fire and if it fires its gotta hit more than 3 times otherwise it doesn't stay running

if the mag is hot, it should fire up & stay running on the 2nd or third compression.

Which does it have a distributor or a Mag?? interment spark if a mag can be an impulse problem. If a distributor it can be caused by dirty points. If it where me I'd check the points and if they look bad replace if still in good shape I'd clean them

Mag

Mag

A mag also has points that at times need to be cleaned. My 1935 JD B sit for a long time with out me firing it up and I have to clean the points when I do try to fire it up

I'll give them a file and gap them and see if that makes a difference

It seems like each 2 cylinder JD has it's own formula to start right. On my old G I put choke to full, throttle 1/2. Generally it will pop when I roll it over (hand start) with second turn. If I catch choke in time it might stay running. Otherwise I go to 1/2 choke and it will start.

Sound like my D. Put the choke on and the second round of compression on the second hump you better have the choke off in one second.
