Medium Flo Jet Emulsion Tube

Mek-a-nik,

You might file this away for later. It is what I found while researching the same problem over a year ago.

There are three coils used on aluminum, single cylinder Briggs to convert from breaker point condenser to electronic as follows:

398593/395489/793281 are used on 2hp to 4hp engines, such as 60000, 80000, 90100, Quattro, and Classic

397358/697037/395490/395491 are used on 5hp engines such as 130000 series flat heads

398811/395492/398265 are used on 7hp to 16hp single cylinder engines, such as 170000, 190000, 280000, and 310000.

Also on most point style engines you can use the universal ignitors with their current coils ( 2 cycle and 4 cycle). They can setup for either polarity.

Thanks KE4AVB.

I'll keep that in my computer and print it out to keep in my truck.

I'm finding sometimes, that when there is a problem that is not making sense on a points engine, it is usually related to the points somehow. I just don't see enough engines with points to be readily familiar with their problems.

I tried a new plug today. No help, but always worth a try. I should've thought of that myself. Could've been a real

Put the 398811 mag on it. It didn't want to go at first, it was 32*f outside.

It agreed to run after a couple pulls. Speed was just a little high at 3900 rpm's. I slowed it down to 3500. I let it warm up and adjusted the high and low mixture screws.

Grabbed some logs and started splitting! It runs very smooth, owner was very happy.
I explained to him that I was past worrying about profit, I wanted to learn why it didn't run. My intuition was correct. A bad mag, or points, condenser.

I posted more information than was necessary, in the hope of helping someone doing a search in the future. I have time for that this time of year. I want to try to add to the info here and build up the site.

Thanks, as usual, for the help I received here. Couldn't have done it without you all.

That a good way to look at it. Sometimes it takes a little self training along with help from others to fix a perplexing problem. There is always a residual effect from this that you can apply later when comes time to do it again. I still make notes on especially hard to resolve problems for later references.

When I first started working on 2 cycles it could easily the better part of day for me to just to find the problem; now it usually takes less 1 hr at the most to complete repairs. Of course there are exceptions that can still drive me batty.

Yes AVB, I figure that I will make a profit in the future on a similiar job because of my experience on this one. Ya gotta learn sometime, right? I'm just glad it was during the slow season. "Problem" jobs are even more of a problem when I get them during the busy season.

I work on 2 cycles on a "I'll see what I can do" basis. (Most of my experience is w/ 4 stroke.) If they're newer box store junk, I only go as far as gas and carb problems. In the fall, I had a low-end leaf blower with a broken throttle cable. The cable was one about $5, but the machine had to be disassembled to install it! Not worth the time. The customer was good with me just wire-tieing the throttle open wide.
I have a chain saw to look at this week. Voicemail says it won't idle down. I'm gonna give it a go. Maybe an air leak somewhere.

I will admit that is a lot work time wise in doing 2C work as the more compact it is the harder is to get things done.

It is the same way when a string trimmer needs a new pull rope. You need to disassemble them near all the way just to get to it. When you do enough of them you get faster at doing as it is almost instinct on what to do and what tools to get out first. I working on getting one those 4 or 5 drawer roll about tool carts that HF has just to keep my 2C tools in. When not in use it tuck would neatly under my wall shelves out the way.

Just replace flywheel on Poulan BVM210 blower. I had to completely remove the engine's housing just to do it. I know my labor is low but it only took me 30 minutes and I charge the one minimum. He got it back for a little under $60 and is very happy as he uses it semi-commercial. The other blower he brought in was back over by his daughter but only had a broken carburetor adapter. When it was all done I made $67 in profit for less than an hour's work.

I do have a low end cutoff point of if it is cost less $100 for them to purchase I recommend just replacing it but sometimes the customer insists on repairs.
