Need help with my skidloader , Onan engine

I have a small skidloader { 4130 IH ] it has a Onan engine in it { was told it's a 18 hp , not sure on that }
my problem is I can't find points or condenser ... Have to get them from the tractor
IH store and they haven't found any yet { been order before Christmas } was giving it a tune up { it's been 5 years } got new plugs and wiring ..
it's banging and poping when it gets warm up ... I'm thinking points ..

condenser - N9630 , points - N9631 these are the numbers I need ..

Anyone has any idea , I'm listening ..
THANKS for any HELP you can give me ............ mark

A year ago I got tune up parts for an Onan in a Case pipe puller at the Cummins dealer here in Saginaw, Michigan.

Do those look like what you need?

When I have that problem I take the old point to the auto parts store and most of the time they can find a set to match

I would go to a small engine lawnmower repair pair shop. They should be able to cross reference you numbers. I just went through this with the 18 horse Onan in the Case we are working on. Local shop was able to get them. Case, IH, John Deere all used Onan engines of some type. If it still has the engine tag on to of it that would help a shop find them.

I didn't take cover off , was in a big hurry tonite .. if I remember right
that is what they look right .. will look at them tomorrow nite after I get
off work ...
THANKS ... mark

I've gotten them from both Napa and jd

IH ONLY used Onan engines in that 4130 skid steer and the 982 Cub Cadet. B48G was the model number. If your CIH dealer can't get the parts they are lazy. I had to replace points & condenser at least once a year in my 982, which is why I bought a Cub Cadet 27 hp Zero turn with a Kawasaki engine, it gets an oil & filter change once a year, about every 25 hours. Deere used lots more Onan engines than IH did. Very distinct design errors in the Onan engines, some will cause sudden catastrophic engine failure, others just poor running.
Do a search for a local CUMMINS engine parts & service shop, they should have the points & condenser or can get them. They will need the model number, spec number, and serial number of your engine. LAST points & Condensor I bought 6-7 years ago was around $140 with shipping. SEE why I parked my 982? The last 3 sets of points/condensors had only lasted 40-50 hours each. And hope and pray your fuel pump never goes bad, I bought one around 2005, was over $110 back then.
I always had the feeling when I started that 982 that something terribly expensive was going to fail in that ONAN engine. And most times something did.

I bet one of the talented people we have on here could put an electronic ignition system on an Onan!

He will have whatever you need and can offer expert advice if needed.

Take the points out and clean them, put them back in and adjust to specs. will probably run like new.
