It'e cast iron, but the module replaces the points and condensor. The module is on a bracket and looks like it can be moved left to right. Also, the depth gauge can go from about 9 one-thousandth to 12 one-thousandth. The spark is very faint, yellow and weak, and the engine kicks back, so he thinks the timing is too far advanced. We were hoping for some specs on how to set it. He thinks the old set up was ok, but the push-pin is worn and is now obsolete, so now he's trying to make this new set-up work, as that is what Briggs is selling to replace the old. This does away with the points and condensor system.

The magnetron conversion doesn't work with all briggs eng,briggs admits that on a small percentage of it's mod# eng it won't work due to flywheel issues(reverse magnet polarity,number of magnets on flywheel or weak magnets)in addition depending on type/code# of eng the 320000 series used point type ign or solid state according to my lookup & lists 2 different pn coils,1 for point type ign & the other solid state,the early solid state system had an ext trigger module mounted on coil,later versions had trigger internal in coil,you must have correct pn flywheel for solid state system to work/work correctly on this style system.

As has been said you're probably better off sticking with point type ign system.The 320000 series eng had adjustable flywheel timing,first thing to do is take orig coil to one/more local mower shops & have coil checked in a coil tester,same may be bad/weak,if coil checks ok then I would suspect problem is dirty/burned point contacts,worn push pin,bad condenser,wire to coil shorting to block,incorrect flywheel/coil air gap or weak flywheel magnets,goto link below & read text,will tell you how to set point/flywheel timing.

The fiber push pin for points is still avail(probably pn 298125)to confirm correct pn for pin goto & lookup eng mod/type numbers in briggs eng parts listings,after you have correct part# for push pin(plunger)do a goggle search for briggs+pn,same still listed on ebay & online dealers.

I also get AOL with the FIOS and I really like it better. You can receive and send emails on both, but I usually use AOL. Pictures can be attached to the emails. Hal

Hi Joe, I have FIOS and they're having a sale now. You can get the internet, free local phone calls and about 300 channels of TV. Cost is about $89.00 for one TV set. They installed all new fiber optic cables in my area in 2009. I even helped to pull some cables. We had Comcast for years, but gave it up when they took off channels and put the price up. Hal

If you can't get link to work,just keep trying,in the past 3-4 wks my dialup dsl service has slowed to 14k-28k or just stopped working,I don't know if this is being caused by verizon,earthlink or aol,I haven't been able to get a straight answer out of any of them.

Verizon wants me to change over to their fios system & I won't so I don't if the're slowing me down,earthlink has connection issues that they won't admit to as I haven't been able to download my emails for two days & it sometimes takes 30 sec-2 min to connect to their ip site which transfers to aol which is slow connecting after leaving home pg,I don't know if its one or all three working against me,all I can say is keep trying link to see if you can connect.

I'm ready to dump the whole thing & goto satellite or cable.

Hi Hal,you're correct somehow the S slipped in there this morning(must have been thinking of toro manual/parts lookup).

Rosemary if you're still following goto link below,that's correct address.

Hal-as far as verizon,I only want their service for internet/phone,they can't even come close to my dish network plan as far as number of movie & other channels and price,I also have optium & comcast in may area offering cable internet/phone service and have to check out prices from them.Right now I have dialup with copper wire,its my understanding verizon dosen't want to be bothered maintaining this type of system,also they have a new policy as far as service on copper lines,if you have 2 service calls in 6 months they switch you over to fiber optic weather you want to or not.If you want to spend an unpleasent evening or two of reading goggle verizon fios+complaints,there's some real horror stories posted,the last thing I would ever do is give verizon my email address,bank account# or cc# not to mention their almost non-existant customer service/tech support.

If it is a cast iron engine, the magnetron ignition will not work unless you reverse the polarity of the flywheel magnets, that is why the fire is weak and out of time, Get a set of points, put old coil back on it set new points at .020, coil gap at .010 and you should be good to go. That ignition system is pretty simple and reliable as it was manufactured. Jim

Its been my experience that those modules don't work on the old cast iron Briggs, for one thing the cast iron engine's magnets are reverse polarity to the newer engines you can try reversing the + / - leads on the module. Those engine with the external points are very good engines but the points and condemner needs to be in good working order, it could also be the coil that is weak. I'd go back to the points but that's me.

Ok I see you replied as I was posting so please tell me when you say electronic module are you talking about the Nova type points eliminator, or the B&S magnetron electronic system?

Magnetron. In fact, he picked up 2 parts. One is from NAPA and was just supposed to be a new coil. The other is from a hardware/Briggs dealer and is the module. They both look the same, except one has a nodule that would bring it closer to the magnet on the flywheel. Another guy he knows installed one of these on his old Speedex and seems to have the same problem. Sometimes it will start, or not, or if he has it running and shuts it off, it may not start again. Very frustrating!
