Thanks, Rusty. Is there a thread here on adjusting the multifuel IP externally?

I ordered a set of 6 injectors from TaylorTradingCo, as reported upthread. They arrived promptly, in good condition, and properly packed for shipment in their original boxes. I installed them in my 1969 M756A2 and found they did not solve the cold starting problem of my multifuel engine. So...

Ordered. By the way, silicon bronze, or brass washers will not work, because they are too hard. Only copper washers should be used for sealing the injectors.

Brass washers will not work properly as crush washers. Crush washers need to be made of copper, preferably annealed copper washers. Also, Swagelock fittings are not rated for 3000 PSI. However, "autoclave" fittings are. Another tip is stainless steel ferrules do not deform well, so it is...

This is a good question. I happen to have 2 sets of 1-hole injectors for my M756A2. I will try to locate a set of 2-hole injectors for testing with alternative diesel fuels. I did notice that my old 1-hole set was badly coked after running them on alternative diesel fuel for only about 40...

Yes, I ordered a set and installed them this weekend, and fired up the deuce yesterday. It now runs with about 2x power, and half the smoke. I still plan to get the old set functional for backup.

No. It is lacquer, which comes from burning waste vegetable oil (WVO) as fuel.

I found the local hardware store normally carries it, but was out, so I bought a gallon of lacquer thinner. Ultrasonically cleaning the injectors for a weekend in the lacquer thinner certainly removed more lacquer from the injectors, but the nozzle is still stuck in the nozzle holder. I like...

I have tried Acetone, but it won't touch the injector coke or lacquer. ATF sounds good. I will give it a try. Thanks.

Last weekend I tried ultra-sonically cleaning the 2 stuck injectors in a gallon of fresh lacquer thinner. It got more crud off, but did not get the injectors unstuck. I also tried heating 1 injector that is glued with lacquer from burning vegetable oil as fuel. I heated it to 550F with a...

I ultra-sonically cleaned the 2 injectors, and 2 hydraulic heads from the injector pumps from my 6.2L Chevy van. While I definitely saw progress in sediment loads on the bottom of the ultra-sonic, they are still stuck together. Next weekend I plan to try MEK as a solvent.

Thanks, yes I probed both holes with the .015 wire, and got 4 of the injectors cleaned. This weekend I plan to try gasoline as a cleaning solvent to see if it helps get the last 2 injectors cleaned up.

Thanks, pjwest03, for the suggestions. Yes, I find an ultra-sonic cleaner is essential equipment for cleaning my injectors. I used a 1qt one to clean my 6.2L injectors for years. I now have a 2qt one for the large injectors for the deuce. The 2 stuborn injectors have been ultra-sonically...

Thanks, folks for your recommendations. I noticed MEK has made a come-back, and it is my understanding that it was removed because people who illegally made crystal meth were using MEK as a precursor to their brew. Mineral spirits, on the other hand, works fine as a general solvent, but I was...

I believe it will be possible to purchase an adapter, so I am looking into that. This weekend I dismantled and serviced 4 of the 6 injectors for my deuce. It would be useful if there was a carbon solvent available. The manual suggests using "P-D-680, DRY CLEANING AND DEGREASING SOLVENT as a...

Since filter cups are not coming my way, it occurred to me that the corroded filter cups could be made serviceable by installing a flat seal with a washer under each of the filter cups. I will try it and see how it works, before reporting back.

I forgot to mention that the adapter needed for testing the deuce injectors is 1/2" fine thread rh, with the threads on the outside of the nut. The guy who provides a very nice adapter kit for the stock Bosh injector pop tester on eBay said, I plan to order it ASAP, and will let you all know...

Last weekend I found my pop tester above did not work. I expect that either they need to be used regularly, or these cheap pop testers from India do not last long, because I only used in about 5 times in 5 years. This kit, above, has adapters for just about every diesel engine in use since...

Another thing we need to track down for servicing our injectors is a shim kit to adjust their pop pressure. Perhaps someone here knows where we can get a shim kit?

Making your own might work out well, but a pop tester can be bought on eBay for $110, http://www.ebay.com/itm/Diesel-Injector-Nozzle-Pop-Tester-with-0-600-BAR-0-8000-PSI-Dual-Scale-Gauge-/302352587887?epid=1756604091&hash=item46659e5c6f:g:EwUAAOSwiQ9ZRPs1. The adapter kit that will work for the...
