Just to follow up on this, I filled my tank with non-ethanol 91 and drove @ 270 miles. I then filled up again. it reduced the spark knock at WOT by a little, but did not eliminate it. I then checked the plugs, they were Autolite 85's. After doing some research on colder plugs, I said the heck...

In the four stroke turbo snowmobile world, this is considered the best.

Valvoline has a new oil called "restore and protect" Lake Speed JR. does a dive into it on his you tube channel. Unfortunate, I don't see any 10-30,10-40 available.

I took the number on the FBO plate to mean total mechanical advance, 16 meaning limited to 16 degrees of advance. I measured the 16 degree slot and it was slightly over .390 I thought the number printed on the stock advance plate was half of what was measured with a timing light, i.e. my plate...

After installing a "new" NOS switch, my compressor won't shut off in any position. After some diag, I found the new switch to be faulty. The "off" position dose not cut power to the compressor. It only works if I press the "off" button, then pull that button back out manually, then the power is...

plate at 16, initial at 18 and light springs-----spark knock at accel in 40-50mph range. I backed off the timing to 15 degrees and only have slight knock at heavy loads, high end acceleration. I filled it with 91 non-ethenol last night and will see if it changes. I will keep tweaking it. The...

Do you think my decision to run the plate at 16, initial at 18 and light springs is a wise one? That theoretically will give me full @34 mech at @1800 and full vacuum advance @49-50 degrees

I did go to @2600 and did not see the advance move but did not go further, maybe a mistake on my part.

Fuel cost is not an issue, my wife owns a gas station!!!! Is it possible that although I think it is stopping advancing at 2000 rpm it is actually coming against the heavy spring, and then going higher later in the rpm range? I need to try it at 3000 rpm I guess. My FBO plate arrives today. I am...

Does 14 degrees mech. advance seem low?

I had been running 91 non-ethanol but the last fill went with 87. Forgot to mention new vacuum advance can also.

bone stock. Previous owner installed a new timing chain. @77k

I recently did a distributor rebuild on my 68 Chrysler 440 TNT. New bushings, new/used shaft and a Pertronix ignitor and Pertronix coil. Ballast resistor bypassed. The car seemed to run "ok" but seemed to be lacking to me. It felt like there was more on the table. The timing was set to the...

I was working on a 1982 Toyota truck with a webber carb 2 weeks ago. Extended crank when hot. After a test drive and a 5 minute soak, I observed fuel being pushed into the carb, flooding the engine and causing extended crank on hot start. Luckily, these trucks have a clear factory fuel filter...

I have yet to get into diagnosing my a/c clutch power situation BUT now the clutch runs all the time! The only way to shut it off is in the "off" position on the heater switch. I am leaning towards a switch assembly if I cant clean it up.
