Chainsaw Repair

I have used the POR15, it works GREAT, and does everything it says it does but $$$$$$$!

Cost is why I haven't even tried it.  Always heard positive review on the products.  Would like to try it tho.

I have been doing some muffler experiments and thought I would also test some different paints. As said earlier I tried DEI high temp from an auto parts store, then went to Home Despot to get tire rust reformer and grill paint Shep uses, whilst there I noticed Rustoleum HT automotive paint so got a can of that. So far on the five mufflers I am working with I have this to report.

DEI as applied it provides a slightly burnished appearance. More than one light coat is necessary to get good coverage. Must be baked on @400° for 30 minutes to fully cure. If you aren't meticulous in your prep it will flake off.

Rust Reformer works great

Rustoleum HT automotive flat black when cured for 30 minutes @250°. Two light coats for good coverage.

Grill paint, have not tried it yet.

cut down willow memorial day.  turned into a project involving a jeep, chains and cables.  brought the temp guage outside but forgot about it.

used it for chicken and turkey on the grill, however.  birds ran about 185.

will get some when bucking it up.

Heck I like the readings you took.   Gives me more of a real world idea of what exhaust temps are.

from what was told, don't believe it has a typical cat muffler.

an interesting find that showed up during the temp readings, was the amount of temperature drop in the muffler as the saw was idled down.  went down almost 50 degrees almost immediately. 

the above temp readings had to be taken very quickly, to be accurate.

another interesting thing was how quickly the temps went up from cold.  it was like an large initial spike, as the saw was loaded as time went on, the temperature dropped.  hard to tell by what i wrote down, but that was the case.

to get an idea of how much load on the saw there was during the 22 minutes of runtime the saw had, it burned almost 3/4 of a tank of fuel.  60cc saw.
